a62982ffb6 ui/crumbs/tasklistmodel: fix saving recipes
After switching to dynamically finding the relative path for the recipe
file it's no longer to append .bb when inserting the require line into the
saved recipe.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:

OE-Core aims to be able to provide basic LSB compatible images. There
are some challenges for OE as LSB isn't always 100% relevant to its
target embedded and IoT audiences.
One challenge is that the LSB spec is no longer being actively
developed [https://github.com/LinuxStandardBase/lsb] and has
components which are end of life or significantly dated. OE
therefore provides compatibility with the following caveats:
* Qt4 is provided by the separate meta-qt4 layer. Its noted that Qt4
is end of life and this isn't something the core project regularly
tests any longer. Users are recommended to group together to support
maintenance of that layer. [http://git.yoctoproject.org/cgit/cgit.cgi/meta-qt4/]
* mailx has been dropped since its no longer being developed upstream
and there are better, more modern replacements such as s-nail
(http://sdaoden.eu/code.html) or mailutils (http://mailutils.org/).
* A few perl modules that were required by LSB 4.x aren't provided:
libclass-isa, libenv, libdumpvalue, libfile-checktree,
libi18n-collate, libpod-plainer.
* libpng 1.2 isn't provided; oe-core includes the latest release of libpng
instead.
* pax (POSIX standard archive) tool is not provided.

OpenEmbedded-Core
=================
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "nodistro") and contains only emulated machine support.

Poky Hardware README
====================
This file gives details about using Poky with different hardware reference
boards and consumer devices. A full list of target machines can be found by
looking in the meta/conf/machine/ directory. If in doubt about using Poky with
your hardware, consult the documentation for your board/device.
Support for additional devices is normally added by creating BSP layers - for
more information please see the Yocto Board Support Package (BSP) Developer's
Guide - documentation source is in documentation/bspguide or download the PDF
from:
http://yoctoproject.org/community/documentation
Support for machines other than QEMU may be moved out to separate BSP layers in
future versions.
QEMU Emulation Targets
======================
To simplify development Poky supports building images to work with the QEMU
emulator in system emulation mode. Several architectures are currently
supported:
* ARM (qemuarm)
* x86 (qemux86)
* x86-64 (qemux86-64)
* PowerPC (qemuppc)
* MIPS (qemumips)
Use of the QEMU images is covered in the Poky Reference Manual. The Poky
MACHINE setting corresponding to the target is given in brackets.
Hardware Reference Boards
=========================
The following boards are supported by Poky's core layer:
* Texas Instruments Beagleboard (beagleboard)
* Freescale MPC8315E-RDB (mpc8315e-rdb)
* Ubiquiti Networks RouterStation Pro (routerstationpro)
For more information see the board's section below. The Poky MACHINE setting
corresponding to the board is given in brackets.
Consumer Devices
================
The following consumer devices are supported by Poky's core layer:
* Intel Atom based PCs and devices (atom-pc)
For more information see the device's section below. The Poky MACHINE setting
corresponding to the device is given in brackets.
Specific Hardware Documentation
===============================
Intel Atom based PCs and devices (atom-pc)
==========================================
The atom-pc MACHINE is tested on the following platforms:
o Asus eee901
o Acer Aspire One
o Toshiba NB305
o Intel Embedded Development Board 1-N450 (Black Sand)
and is likely to work on many unlisted atom based devices. The MACHINE type
supports ethernet, wifi, sound, and i915 graphics by default in addition to
common PC input devices, busses, and so on.
Depending on the device, it can boot from a traditional hard-disk, a USB device,
or over the network. Writing poky generated images to physical media is
straightforward with a caveat for USB devices. The following examples assume the
target boot device is /dev/sdb, be sure to verify this and use the correct
device as the following commands are run as root and are not reversable.
Hard Disk:
1. Build a directdisk image format. This will generate proper partition tables
that will in turn be written to the physical media. For example:
$ bitbake core-image-minimal-directdisk
2. Use the "dd" utility to write the image to the raw block device. For example:
# dd if=core-image-minimal-directdisk-atom-pc.hdddirect of=/dev/sdb
USB Device:
1. Build an hddimg image format. This is a simple filesystem without partition
tables and is suitable for USB keys. For example:
$ bitbake core-image-minimal-live
2. Use the "dd" utility to write the image to the raw block device. For
example:
# dd if=core-image-minimal-live-atom-pc.hddimg of=/dev/sdb
If the device fails to boot with "Boot error" displayed, it is likely the BIOS
cannot understand the physical layout of the disk (or rather it expects a
particular layout and cannot handle anything else). There are two possible
solutions to this problem:
1. Change the BIOS USB Device setting to HDD mode. The label will vary by
device, but the idea is to force BIOS to read the Cylinder/Head/Sector
geometry from the device.
2. Without such an option, the BIOS generally boots the device in USB-ZIP
mode.
a. Configure the USB device for USB-ZIP mode:
# mkdiskimage -4 /dev/sdb 0 63 62
Where 63 and 62 are the head and sector count as reported by fdisk.
Remove and reinsert the device to allow the kernel to detect the new
partition layout.
b. Copy the contents of the poky image to the USB-ZIP mode device:
# mount -o loop core-image-minimal-live-atom-pc.hddimg /tmp/image
# mount /dev/sdb4 /tmp/usbkey
# cp -rf /tmp/image/* /tmp/usbkey
c. Install the syslinux boot loader:
# syslinux /dev/sdb4
Install the boot device in the target board and configure the BIOS to boot
from it.
For more details on the USB-ZIP scenario, see the syslinux documentation:
http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=blob_plain;f=doc/usbkey.txt;hb=HEAD
Texas Instruments Beagleboard (beagleboard)
===========================================
The Beagleboard is an ARM Cortex-A8 development board with USB, DVI-D, S-Video,
2D/3D accelerated graphics, audio, serial, JTAG, and SD/MMC. The xM adds a
faster CPU, more RAM, an ethernet port, more USB ports, microSD, and removes
the NAND flash. The beagleboard MACHINE is tested on the following platforms:
o Beagleboard C4
o Beagleboard xM Rev A
The Beagleboard C4 has NAND, while the xM does not. For the sake of simplicity,
these instructions assume you have erased the NAND on the C4 so its boot
behavior matches that of the xM. To do this, issue the following commands from
the u-boot prompt (note that the unlock may be unecessary depending on the
version of u-boot installed on your board and only one of the erase commands
will succeed):
# nand unlock
# nand erase
# nand erase.chip
To further tailor these instructions for your board, please refer to the
documentation at http://www.beagleboard.org.
From a Linux system with access to the image files perform the following steps
as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
if used via a usb card reader):
1. Partition and format an SD card:
# fdisk -lu /dev/mmcblk0
Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 63 144584 72261 c Win95 FAT32 (LBA)
/dev/mmcblk0p2 144585 465884 160650 83 Linux
# mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
# mke2fs -j -L "root" /dev/mmcblk0p2
The following assumes the SD card partition 1 and 2 are mounted at
/media/boot and /media/root respectively. Removing the card and reinserting
it will do just that on most modern Linux desktop environments.
The files referenced below are made available after the build in
build/tmp/deploy/images.
2. Install the boot loaders
# cp MLO-beagleboard /media/boot/MLO
# cp u-boot-beagleboard.bin /media/boot/u-boot.bin
3. Install the root filesystem
# tar x -C /media/root -f core-image-$IMAGE_TYPE-beagleboard.tar.bz2
# tar x -C /media/root -f modules-$KERNEL_VERSION-beagleboard.tgz
4. Install the kernel uImage
# cp uImage-beagleboard.bin /media/boot/uImage
5. Prepare a u-boot script to simplify the boot process
The Beagleboard can be made to boot at this point from the u-boot command
shell. To automate this process, generate a user.scr script as follows.
Install uboot-mkimage (from uboot-mkimage on Ubuntu or uboot-tools on Fedora).
Prepare a script config:
# (cat << EOF
setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
setenv bootargs 'console=tty0 console=ttyO2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro'
boot
EOF
) > serial-boot.cmd
# mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Core Minimal" -d ./serial-boot.cmd ./boot.scr
# cp boot.scr /media/boot
6. Unmount the SD partitions, insert the SD card into the Beagleboard, and
boot the Beagleboard
Note: As of the 2.6.37 linux-yocto kernel recipe, the Beagleboard uses the
OMAP_SERIAL device (ttyO2). If you are using an older kernel, such as the
2.6.34 linux-yocto-stable, be sure to replace ttyO2 with ttyS2 above. You
should also override the machine SERIAL_CONSOLE in your local.conf in
order to setup the getty on the serial line:
SERIAL_CONSOLE_beagleboard = "115200 ttyS2"
Freescale MPC8315E-RDB (mpc8315e-rdb)
=====================================
The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
software development of network attached storage (NAS) and digital media server
applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
includes a built-in security accelerator.
Setup instructions
------------------
You will need the following:
* nfs root setup on your workstation
* tftp server installed on your workstation
Load the kernel and boot it as follows:
1. Get the kernel (uImage.mpc8315erdb) and dtb (mpc8315erdb.dtb) files from
the Poky build tmp/deploy directory, and make them available on your tftp
server.
2. Set up the environment in U-Boot:
=>setenv ipaddr <board ip>
=>setenv serverip <tftp server ip>
=>setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
3. Download kernel and dtb to boot kernel.
=>tftp 800000 uImage.mpc8315erdb
=>tftp 780000 mpc8315erdb.dtb
=>bootm 800000 - 780000
Ubiquiti Networks RouterStation Pro (routerstationpro)
======================================================
The RouterStation Pro is an Atheros AR7161 MIPS-based board. Geared towards
networking applications, it has all of the usual features as well as three
type IIIA mini-PCI slots and an on-board 3-port 10/100/1000 Ethernet switch,
in addition to the 10/100/1000 Ethernet WAN port which supports
Power-over-Ethernet.
Setup instructions
------------------
You will need the following:
* A serial cable - female to female (or female to male + gender changer)
NOTE: cable must be straight through, *not* a null modem cable.
* USB flash drive or hard disk that is able to be powered from the
board's USB port.
* tftp server installed on your workstation
NOTE: in the following instructions it is assumed that /dev/sdb corresponds
to the USB disk when it is plugged into your workstation. If this is not the
case in your setup then please be careful to substitute the correct device
name in all commands where appropriate.
--- Preparation ---
1) Build an image (e.g. core-image-minimal) using "routerstationpro" as the
MACHINE
2) Partition the USB drive so that primary partition 1 is type Linux (83).
Minimum size depends on your root image size - core-image-minimal probably
only needs 8-16MB, other images will need more.
# fdisk /dev/sdb
Command (m for help): p
Disk /dev/sdb: 4011 MB, 4011491328 bytes
124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0009e87d
Device Boot Start End Blocks Id System
/dev/sdb1 62 1952751 976345 83 Linux
3) Format partition 1 on the USB as ext3
# mke2fs -j /dev/sdb1
4) Mount partition 1 and then extract the contents of
tmp/deploy/images/core-image-XXXX.tar.bz2 into it (preserving permissions).
# mount /dev/sdb1 /media/sdb1
# cd /media/sdb1
# tar -xvjpf tmp/deploy/images/core-image-XXXX.tar.bz2
5) Unmount the USB drive and then plug it into the board's USB port
6) Connect the board's serial port to your workstation and then start up
your favourite serial terminal so that you will be able to interact with
the serial console. If you don't have a favourite, picocom is suggested:
$ picocom /dev/ttyUSB0 -b 115200
7) Connect the network into eth0 (the one that is NOT the 3 port switch). If
you are using power-over-ethernet then the board will power up at this point.
8) Start up the board, watch the serial console. Hit Ctrl+C to abort the
autostart if the board is configured that way (it is by default). The
bootloader's fconfig command can be used to disable autostart and configure
the IP settings if you need to change them (default IP is 192.168.1.20).
9) Make the kernel (tmp/deploy/images/vmlinux-routerstationpro.bin) available
on the tftp server.
10) If you are going to write the kernel to flash (optional - see "Booting a
kernel directly" below for the alternative), remove the current kernel and
rootfs flash partitions. You can list the partitions using the following
bootloader command:
RedBoot> fis list
You can delete the existing kernel and rootfs with these commands:
RedBoot> fis delete kernel
RedBoot> fis delete rootfs
--- Booting a kernel directly ---
1) Load the kernel using the following bootloader command:
RedBoot> load -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin
You should see a message on it being successfully loaded.
2) Execute the kernel:
RedBoot> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
Note that specifying the command line with -c is important as linux-yocto does
not provide a default command line.
--- Writing a kernel to flash ---
1) Go to your tftp server and gzip the kernel you want in flash. It should
halve the size.
2) Load the kernel using the following bootloader command:
RedBoot> load -r -b 0x80600000 -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin.gz
This should output something similar to the following:
Raw file loaded 0x80600000-0x8087c537, assumed entry at 0x80600000
Calculate the length by subtracting the first number from the second number
and then rounding the result up to the nearest 0x1000.
3) Using the length calculated above, create a flash partition for the kernel:
RedBoot> fis create -b 0x80600000 -l 0x240000 kernel
(change 0x240000 to your rounded length -- change "kernel" to whatever
you want to name your kernel)
--- Booting a kernel from flash ---
To boot the flashed kernel perform the following steps.
1) At the bootloader prompt, load the kernel:
RedBoot> fis load -d -e kernel
(Change the name "kernel" above if you chose something different earlier)
(-e means 'elf', -d 'decompress')
2) Execute the kernel using the exec command as above.
--- Automating the boot process ---
After writing the kernel to flash and testing the load and exec commands
manually, you can automate the boot process with a boot script.
1) RedBoot> fconfig
(Answer the questions not specified here as they pertain to your environment)
2) Run script at boot: true
Boot script:
.. fis load -d -e kernel
.. exec
Enter script, terminate with empty line
>> fis load -d -e kernel
>> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
>>
3) Answer the remaining questions and write the changes to flash:
Update RedBoot non-volatile configuration - continue (y/n)? y
... Erase from 0xbfff0000-0xc0000000: .
... Program from 0x87ff0000-0x88000000 at 0xbfff0000: .
4) Power cycle the board.

QEMU Emulation Targets
======================
To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:
* ARM (qemuarm + qemuarm64)
* x86 (qemux86 + qemux86-64)
* PowerPC (qemuppc only)
* MIPS (qemumips + qemumips64)
Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

Bitbake
=======
BitBake is a generic task execution engine that allows shell and Python tasks to be run
efficiently and in parallel while working within complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website:
http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated
html version at the Yocto Project website:
http://yoctoproject.org/documentation
Contributing
------------
Please refer to
http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
for guidelines on how to submit patches, just note that the latter documentation is intended
for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org)
but in general main guidelines apply. Once the commit(s) have been created, the way to send
the patch is through git-send-email. For example, to send the last commit (HEAD) on current
branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org

Documentation
=============
This is the directory that contains the BitBake documentation.
Manual Organization
===================
Folders exist for individual manuals as follows:
* bitbake-user-manual - The BitBake User Manual
Each folder is self-contained regarding content and figures.
If you want to find HTML versions of the BitBake manuals on the web,
go to http://www.openembedded.org/wiki/Documentation.
Makefile
========
The Makefile processes manual directories to create HTML, PDF,
tarballs, etc. Details on how the Makefile work are documented
inside the Makefile. See that file for more information.
To build a manual, you run the make command and pass it the name
of the folder containing the manual's contents.
For example, the following command run from the documentation directory
creates an HTML and a PDF version of the BitBake User Manual.
The DOC variable specifies the manual you are making:
$ make DOC=bitbake-user-manual
template
========
Contains various templates, fonts, and some old PNG files.
tools
=====
Contains a tool to convert the DocBook files to PDF format.

<!DOCTYPE chapter PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">
<chapter id="bitbake-user-manual-execution">
<title>Execution</title>
<para>
The primary purpose for running BitBake is to produce some kind
of output such as a single installable package, a kernel, a software
development kit, or even a full, board-specific bootable Linux image,
complete with bootloader, kernel, and root filesystem.
Of course, you can execute the <filename>bitbake</filename>
command with options that cause it to execute single tasks,
compile single recipe files, capture or clear data, or simply
return information about the execution environment.
</para>
<para>
This chapter describes BitBake's execution process from start
to finish when you use it to create an image.
The execution process is launched using the following command
form:
<literallayout class='monospaced'>
$ bitbake <replaceable>target</replaceable>
</literallayout>
For information on the BitBake command and its options,
see
"<link linkend='bitbake-user-manual-command'>The BitBake Command</link>"
section.
<note>
<para>
Prior to executing BitBake, you should take advantage of available
parallel thread execution on your build host by setting the
<link linkend='var-bb-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
variable in your project's <filename>local.conf</filename>
configuration file.
</para>
<para>
A common method to determine this value for your build host is to run
the following:
<literallayout class='monospaced'>
$ grep processor /proc/cpuinfo
</literallayout>
This command returns the number of processors, which takes into
account hyper-threading.
Thus, a quad-core build host with hyper-threading most likely
shows eight processors, which is the value you would then assign to
<filename>BB_NUMBER_THREADS</filename>.
</para>
<para>
A possibly simpler solution is that some Linux distributions
(e.g. Debian and Ubuntu) provide the <filename>ncpus</filename> command.
</para>
</note>
</para>
<section id='parsing-the-base-configuration-metadata'>
<title>Parsing the Base Configuration Metadata</title>
<para>
The first thing BitBake does is parse base configuration
metadata.
Base configuration metadata consists of your project's
<filename>bblayers.conf</filename> file to determine what
layers BitBake needs to recognize, all necessary
<filename>layer.conf</filename> files (one from each layer),
and <filename>bitbake.conf</filename>.
The data itself is of various types:
<itemizedlist>
<listitem><para><emphasis>Recipes:</emphasis>
Details about particular pieces of software.
</para></listitem>
<listitem><para><emphasis>Class Data:</emphasis>
An abstraction of common build information
(e.g. how to build a Linux kernel).
</para></listitem>
<listitem><para><emphasis>Configuration Data:</emphasis>
Machine-specific settings, policy decisions,
and so forth.
Configuration data acts as the glue to bind everything
together.</para></listitem>
</itemizedlist>
</para>
<para>
The <filename>layer.conf</filename> files are used to
construct key variables such as
<link linkend='var-bb-BBPATH'><filename>BBPATH</filename></link>
and
<link linkend='var-bb-BBFILES'><filename>BBFILES</filename></link>.
<filename>BBPATH</filename> is used to search for
configuration and class files under the
<filename>conf</filename> and <filename>classes</filename>
directories, respectively.
<filename>BBFILES</filename> is used to locate both recipe
and recipe append files
(<filename>.bb</filename> and <filename>.bbappend</filename>).
If there is no <filename>bblayers.conf</filename> file,
it is assumed the user has set the <filename>BBPATH</filename>
and <filename>BBFILES</filename> directly in the environment.
</para>
<para>
Next, the <filename>bitbake.conf</filename> file is located
using the <filename>BBPATH</filename> variable that was
just constructed.
The <filename>bitbake.conf</filename> file may also include other
configuration files using the
<filename>include</filename> or
<filename>require</filename> directives.
</para>
<para>
Prior to parsing configuration files, Bitbake looks
at certain variables, including:
<itemizedlist>
<listitem><para>
<link linkend='var-bb-BB_ENV_WHITELIST'><filename>BB_ENV_WHITELIST</filename></link>
</para></listitem>
<listitem><para>
<link linkend='var-bb-BB_ENV_EXTRAWHITE'><filename>BB_ENV_EXTRAWHITE</filename></link>
</para></listitem>
<listitem><para>
<link linkend='var-bb-BB_PRESERVE_ENV'><filename>BB_PRESERVE_ENV</filename></link>
</para></listitem>
<listitem><para>
<link linkend='var-bb-BB_ORIGENV'><filename>BB_ORIGENV</filename></link>
</para></listitem>
<listitem><para>
<link linkend='var-bb-BITBAKE_UI'><filename>BITBAKE_UI</filename></link>
</para></listitem>
</itemizedlist>
The first four variables in this list relate to how BitBake treats shell
environment variables during task execution.
By default, BitBake cleans the environment variables and provides tight
control over the shell execution environment.
However, through the use of these first four variables, you can
apply your control regarding the
environment variables allowed to be used by BitBake in the shell
during execution of tasks.
See the
"<link linkend='passing-information-into-the-build-task-environment'>Passing Information Into the Build Task Environment</link>"
section and the information about these variables in the
variable glossary for more information on how they work and
on how to use them.
</para>
<para>
The base configuration metadata is global
and therefore affects all recipes and tasks that are executed.
</para>
<para>
BitBake first searches the current working directory for an
optional <filename>conf/bblayers.conf</filename> configuration file.
This file is expected to contain a
<link linkend='var-bb-BBLAYERS'><filename>BBLAYERS</filename></link>
variable that is a space-delimited list of 'layer' directories.
Recall that if BitBake cannot find a <filename>bblayers.conf</filename>
file, then it is assumed the user has set the <filename>BBPATH</filename>
and <filename>BBFILES</filename> variables directly in the environment.
</para>
<para>
For each directory (layer) in this list, a <filename>conf/layer.conf</filename>
file is located and parsed with the
<link linkend='var-bb-LAYERDIR'><filename>LAYERDIR</filename></link>
variable being set to the directory where the layer was found.
The idea is these files automatically set up
<link linkend='var-bb-BBPATH'><filename>BBPATH</filename></link>
and other variables correctly for a given build directory.
</para>
<para>
BitBake then expects to find the <filename>conf/bitbake.conf</filename>
file somewhere in the user-specified <filename>BBPATH</filename>.
That configuration file generally has include directives to pull
in any other metadata such as files specific to the architecture,
the machine, the local environment, and so forth.
</para>
<para>
Only variable definitions and include directives are allowed
in BitBake <filename>.conf</filename> files.
Some variables directly influence BitBake's behavior.
These variables might have been set from the environment
depending on the environment variables previously
mentioned or set in the configuration files.
The
"<link linkend='ref-bb-variables-glos'>Variables Glossary</link>"
chapter presents a full list of variables.
</para>
<para>
After parsing configuration files, BitBake uses its rudimentary
inheritance mechanism, which is through class files, to inherit
some standard classes.
BitBake parses a class when the inherit directive responsible
for getting that class is encountered.
</para>
<para>
The <filename>base.bbclass</filename> file is always included.
Other classes that are specified in the configuration using the
<link linkend='var-bb-INHERIT'><filename>INHERIT</filename></link>
variable are also included.
BitBake searches for class files in a
<filename>classes</filename> subdirectory under
the paths in <filename>BBPATH</filename> in the same way as
configuration files.
</para>
<para>
A good way to get an idea of the configuration files and
the class files used in your execution environment is to
run the following BitBake command:
<literallayout class='monospaced'>
$ bitbake -e > mybb.log
</literallayout>
Examining the top of the <filename>mybb.log</filename>
shows you the many configuration files and class files
used in your execution environment.
</para>
<note>
<para>
You need to be aware of how BitBake parses curly braces.
If a recipe uses a closing curly brace within the function and
the character has no leading spaces, BitBake produces a parsing
error.
If you use a pair of curly braces in a shell function, the
closing curly brace must not be located at the start of the line
without leading spaces.
</para>
<para>
Here is an example that causes BitBake to produce a parsing
error:
<literallayout class='monospaced'>
fakeroot create_shar() {
cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
usage()
{
echo "test"
###### The following "}" at the start of the line causes a parsing error ######
}
EOF
}
</literallayout>
Writing the recipe this way avoids the error:
<literallayout class='monospaced'>
fakeroot create_shar() {
cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
usage()
{
echo "test"
######The following "}" with a leading space at the start of the line avoids the error ######
}
EOF
}
</literallayout>
</para>

<title>Locating and Parsing Recipes</title>
<para>
During the configuration phase, BitBake will have set
<link linkend='var-bb-BBFILES'><filename>BBFILES</filename></link>.
BitBake now uses it to construct a list of recipes to parse,
along with any append files (<filename>.bbappend</filename>)
to apply.
<filename>BBFILES</filename> is a space-separated list of
available files and supports wildcards.
An example would be:
<literallayout class='monospaced'>
BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
</literallayout>
BitBake parses each recipe and append file located
with <filename>BBFILES</filename> and stores the values of
various variables into the datastore.
<note>
Append files are applied in the order they are encountered in
<filename>BBFILES</filename>.
</note>
For each file, a fresh copy of the base configuration is
made, then the recipe is parsed line by line.
Any inherit statements cause BitBake to find and
then parse class files (<filename>.bbclass</filename>)
using
<link linkend='var-bb-BBPATH'><filename>BBPATH</filename></link>
as the search path.
Finally, BitBake parses in order any append files found in
<filename>BBFILES</filename>.
</para>
<para>
One common convention is to use the recipe filename to define
pieces of metadata.
For example, in <filename>bitbake.conf</filename> the recipe
name and version are used to set the variables
<link linkend='var-bb-PN'><filename>PN</filename></link> and
<link linkend='var-bb-PV'><filename>PV</filename></link>:
<literallayout class='monospaced'>
PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}"
</literallayout>
In this example, a recipe called "something_1.2.3.bb" would set
<filename>PN</filename> to "something" and
<filename>PV</filename> to "1.2.3".
</para>
<para>
By the time parsing is complete for a recipe, BitBake
has a list of tasks that the recipe defines and a set of
data consisting of keys and values as well as
dependency information about the tasks.
</para>
<para>
BitBake does not need all of this information.
It only needs a small subset of the information to make
decisions about the recipe.
Consequently, BitBake caches the values in which it is
interested and does not store the rest of the information.
Experience has shown it is faster to re-parse the metadata than to
try and write it out to the disk and then reload it.
</para>
<para>
Where possible, subsequent BitBake commands reuse this cache of
recipe information.
The validity of this cache is determined by first computing a
checksum of the base configuration data (see
<link linkend='var-bb-BB_HASHCONFIG_WHITELIST'><filename>BB_HASHCONFIG_WHITELIST</filename></link>)
and then checking if the checksum matches.
If that checksum matches what is in the cache and the recipe
and class files have not changed, Bitbake is able to use
the cache.
BitBake then reloads the cached information about the recipe
instead of reparsing it from scratch.
</para>
<para>
Recipe file collections exist to allow the user to
have multiple repositories of
<filename>.bb</filename> files that contain the same
exact package.
For example, one could easily use them to make one's
own local copy of an upstream repository, but with
custom modifications that one does not want upstream.
Here is an example:
<literallayout class='monospaced'>
BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
BBFILE_COLLECTIONS = "upstream local"
BBFILE_PATTERN_upstream = "^/stuff/openembedded/"
BBFILE_PATTERN_local = "^/stuff/openembedded.modified/"
BBFILE_PRIORITY_upstream = "5"
BBFILE_PRIORITY_local = "10"
</literallayout>
<note>
The layers mechanism is now the preferred method of collecting
code.
While the collections code remains, its main use is to set layer
priorities and to deal with overlap (conflicts) between layers.
</note>
</para>
</section>
<section id='bb-bitbake-providers'>
<title>Providers</title>
<para>
Assuming BitBake has been instructed to execute a target
and that all the recipe files have been parsed, BitBake
starts to figure out how to build the target.
BitBake looks through the <filename>PROVIDES</filename> list
for each of the recipes.
A <filename>PROVIDES</filename> list is the list of names by which
the recipe can be known.
Each recipe's <filename>PROVIDES</filename> list is created
implicitly through the recipe's
<link linkend='var-bb-PN'><filename>PN</filename></link> variable
and explicitly through the recipe's
<link linkend='var-bb-PROVIDES'><filename>PROVIDES</filename></link>
variable, which is optional.
</para>
<para>
When a recipe uses <filename>PROVIDES</filename>, that recipe's
functionality can be found under an alternative name or names other
than the implicit <filename>PN</filename> name.
As an example, suppose a recipe named <filename>keyboard_1.0.bb</filename>
contained the following:
<literallayout class='monospaced'>
PROVIDES += "fullkeyboard"
</literallayout>
The <filename>PROVIDES</filename> list for this recipe becomes
"keyboard", which is implicit, and "fullkeyboard", which is explicit.
Consequently, the functionality found in
<filename>keyboard_1.0.bb</filename> can be found under two
different names.
</para>
</section>
<section id='bb-bitbake-preferences'>
<title>Preferences</title>
<para>
The <filename>PROVIDES</filename> list is only part of the solution
for figuring out a target's recipes.
Because targets might have multiple providers, BitBake needs
to prioritize providers by determining provider preferences.
</para>
<para>
A common example in which a target has multiple providers
is "virtual/kernel", which is on the
<filename>PROVIDES</filename> list for each kernel recipe.
Each machine often selects the best kernel provider by using a
line similar to the following in the machine configuration file:
<literallayout class='monospaced'>
PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"
</literallayout>
The default
<link linkend='var-bb-PREFERRED_PROVIDER'><filename>PREFERRED_PROVIDER</filename></link>
is the provider with the same name as the target.
Bitbake iterates through each target it needs to build and
resolves them and their dependencies using this process.
</para>
<para>
Understanding how providers are chosen is made complicated by the fact
that multiple versions might exist for a given provider.
BitBake defaults to the highest version of a provider.
Version comparisons are made using the same method as Debian.
You can use the
<link linkend='var-bb-PREFERRED_VERSION'><filename>PREFERRED_VERSION</filename></link>
variable to specify a particular version.
You can influence the order by using the
<link linkend='var-bb-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
variable.
</para>
<para>
By default, files have a preference of "0".
Setting <filename>DEFAULT_PREFERENCE</filename> to "-1" makes the
recipe unlikely to be used unless it is explicitly referenced.
Setting <filename>DEFAULT_PREFERENCE</filename> to "1" makes it
likely the recipe is used.
<filename>PREFERRED_VERSION</filename> overrides any
<filename>DEFAULT_PREFERENCE</filename> setting.
<filename>DEFAULT_PREFERENCE</filename> is often used to mark newer
and more experimental recipe versions until they have undergone
sufficient testing to be considered stable.
</para>
<para>
When there are multiple “versions” of a given recipe,
BitBake defaults to selecting the most recent
version, unless otherwise specified.
If the recipe in question has a
<link linkend='var-bb-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
set lower than the other recipes (default is 0), then
it will not be selected.
This allows the person or persons maintaining
the repository of recipe files to specify
their preference for the default selected version.
Additionally, the user can specify their preferred version.
</para>
<para>
If the first recipe is named <filename>a_1.1.bb</filename>, then the
<link linkend='var-bb-PN'><filename>PN</filename></link> variable
will be set to “a”, and the
<link linkend='var-bb-PV'><filename>PV</filename></link>
variable will be set to 1.1.
</para>
<para>
Thus, if a recipe named <filename>a_1.2.bb</filename> exists, BitBake
will choose 1.2 by default.
However, if you define the following variable in a
<filename>.conf</filename> file that BitBake parses, you
can change that preference:
<literallayout class='monospaced'>
PREFERRED_VERSION_a = "1.1"
</literallayout>
</para>
<note>
<para>
It is common for a recipe to provide two versions -- a stable,
numbered (and preferred) version, and a version that is
automatically checked out from a source code repository that
is considered more "bleeding edge" but can be selected only
explicitly.
</para>
<para>
For example, in the OpenEmbedded codebase, there is a standard,
versioned recipe file for BusyBox,
<filename>busybox_1.22.1.bb</filename>,
but there is also a Git-based version,
<filename>busybox_git.bb</filename>, which explicitly contains the line
<literallayout class='monospaced'>
DEFAULT_PREFERENCE = "-1"
</literallayout>
to ensure that the numbered, stable version is always preferred
unless the developer selects otherwise.
</para>
</note>
</section>
<section id='bb-bitbake-dependencies'>
<title>Dependencies</title>
<para>
Each target BitBake builds consists of multiple tasks such as
<filename>fetch</filename>, <filename>unpack</filename>,
<filename>patch</filename>, <filename>configure</filename>,
and <filename>compile</filename>.
For best performance on multi-core systems, BitBake considers each
task as an independent
entity with its own set of dependencies.
</para>
<para>
Dependencies are defined through several variables.
You can find information about variables BitBake uses in
the <link linkend='ref-bb-variables-glos'>Variables Glossary</link>
near the end of this manual.
At a basic level, it is sufficient to know that BitBake uses the
<link linkend='var-bb-DEPENDS'><filename>DEPENDS</filename></link> and
<link linkend='var-bb-RDEPENDS'><filename>RDEPENDS</filename></link> variables when
calculating dependencies.
</para>
<para>
For more information on how BitBake handles dependencies, see the
"<link linkend='dependencies'>Dependencies</link>" section.
</para>
</section>
<section id='ref-bitbake-tasklist'>
<title>The Task List</title>
<para>
Based on the generated list of providers and the dependency information,
BitBake can now calculate exactly what tasks it needs to run and in what
order it needs to run them.
The
"<link linkend='executing-tasks'>Executing Tasks</link>" section has more
information on how BitBake chooses which task to execute next.
</para>
<para>
The build now starts with BitBake forking off threads up to the limit set in the
<link linkend='var-bb-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
variable.
BitBake continues to fork threads as long as there are tasks ready to run,
those tasks have all their dependencies met, and the thread threshold has not been
exceeded.
</para>
<para>
It is worth noting that you can greatly speed up the build time by properly setting
the <filename>BB_NUMBER_THREADS</filename> variable.
</para>
<para>
As each task completes, a timestamp is written to the directory specified by the
<link linkend='var-bb-STAMP'><filename>STAMP</filename></link> variable.
On subsequent runs, BitBake looks in the build directory within
<filename>tmp/stamps</filename> and does not rerun
tasks that are already completed unless a timestamp is found to be invalid.
Currently, invalid timestamps are only considered on a per
recipe file basis.
So, for example, if the configure stamp has a timestamp greater than the
compile timestamp for a given target, then the compile task would rerun.
Running the compile task again, however, has no effect on other providers
that depend on that target.
</para>
<para>
The exact format of the stamps is partly configurable.
In modern versions of BitBake, a hash is appended to the
stamp so that if the configuration changes, the stamp becomes
invalid and the task is automatically rerun.
This hash, or signature used, is governed by the signature policy
that is configured (see the
"<link linkend='checksums'>Checksums (Signatures)</link>"
section for information).
It is also possible to append extra metadata to the stamp using
the <filename>[stamp-extra-info]</filename> task flag.
For example, OpenEmbedded uses this flag to make some tasks machine-specific.
</para>
<note>
Some tasks are marked as "nostamp" tasks.
No timestamp file is created when these tasks are run.
Consequently, "nostamp" tasks are always rerun.
</note>
<para>
For more information on tasks, see the
"<link linkend='tasks'>Tasks</link>" section.
</para>
</section>
<section id='executing-tasks'>
<title>Executing Tasks</title>
<para>
Tasks can be either a shell task or a Python task.
For shell tasks, BitBake writes a shell script to
<filename>${</filename><link linkend='var-bb-T'><filename>T</filename></link><filename>}/run.do_taskname.pid</filename>
and then executes the script.
The generated shell script contains all the exported variables,
and the shell functions with all variables expanded.
Output from the shell script goes to the file
<filename>${T}/log.do_taskname.pid</filename>.
Looking at the expanded shell functions in the run file and
the output in the log files is a useful debugging technique.
</para>
<para>
For Python tasks, BitBake executes the task internally and logs
information to the controlling terminal.
Future versions of BitBake will write the functions to files
similar to the way shell tasks are handled.
Logging will be handled in a way similar to shell tasks as well.
</para>
<para>
The order in which BitBake runs the tasks is controlled by its
task scheduler.
It is possible to configure the scheduler and define custom
implementations for specific use cases.
For more information, see these variables that control the
behavior:
<itemizedlist>
<listitem><para>
<link linkend='var-bb-BB_SCHEDULER'><filename>BB_SCHEDULER</filename></link>
</para></listitem>
<listitem><para>
<link linkend='var-bb-BB_SCHEDULERS'><filename>BB_SCHEDULERS</filename></link>
</para></listitem>
</itemizedlist>
It is possible to have functions run before and after a task's main
function.
This is done using the <filename>[prefuncs]</filename>
and <filename>[postfuncs]</filename> flags of the task
that lists the functions to run.
</para>
</section>
<section id='checksums'>
<title>Checksums (Signatures)</title>
<para>
A checksum is a unique signature of a task's inputs.
The signature of a task can be used to determine if a task
needs to be run.
Because it is a change in a task's inputs that triggers running
the task, BitBake needs to detect all the inputs to a given task.
For shell tasks, this turns out to be fairly easy because
BitBake generates a "run" shell script for each task and
it is possible to create a checksum that gives you a good idea of when
the task's data changes.
</para>
<para>
To complicate the problem, some things should not be included in
the checksum.
First, there is the actual specific build path of a given task -
the working directory.
It does not matter if the working directory changes because it should not
affect the output for target packages.
The simplistic approach for excluding the working directory is to set
it to some fixed value and create the checksum for the "run" script.
BitBake goes one step better and uses the
<link linkend='var-bb-BB_HASHBASE_WHITELIST'><filename>BB_HASHBASE_WHITELIST</filename></link>
variable to define a list of variables that should never be included
when generating the signatures.
</para>
<para>
Another problem results from the "run" scripts containing functions that
might or might not get called.
The incremental build solution contains code that figures out dependencies
between shell functions.
This code is used to prune the "run" scripts down to the minimum set,
thereby alleviating this problem and making the "run" scripts much more
readable as a bonus.
</para>
<para>
So far we have solutions for shell scripts.
What about Python tasks?
The same approach applies even though these tasks are more difficult.
The process needs to figure out what variables a Python function accesses
and what functions it calls.
Again, the incremental build solution contains code that first figures out
the variable and function dependencies, and then creates a checksum for the data
used as the input to the task.
</para>
<para>
Like the working directory case, situations exist where dependencies
should be ignored.
For these cases, you can instruct the build process to ignore a dependency
by using a line like the following:
<literallayout class='monospaced'>
PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
</literallayout>
This example ensures that the <filename>PACKAGE_ARCHS</filename> variable does not
depend on the value of <filename>MACHINE</filename>, even if it does reference it.
</para>
<para>
Equally, there are cases where we need to add dependencies BitBake
is not able to find.
You can accomplish this by using a line like the following:
<literallayout class='monospaced'>
PACKAGE_ARCHS[vardeps] = "MACHINE"
</literallayout>
This example explicitly adds the <filename>MACHINE</filename> variable as a
dependency for <filename>PACKAGE_ARCHS</filename>.
</para>
<para>
Consider a case with in-line Python, for example, where BitBake is not
able to figure out dependencies.
When running in debug mode (i.e. using <filename>-DDD</filename>), BitBake
produces output when it discovers something for which it cannot figure out
dependencies.
</para>
<para>
Thus far, this section has limited discussion to the direct inputs into a task.
Information based on direct inputs is referred to as the "basehash" in the
code.
However, there is still the question of a task's indirect inputs - the
things that were already built and present in the build directory.
The checksum (or signature) for a particular task needs to add the hashes
of all the tasks on which the particular task depends.
Choosing which dependencies to add is a policy decision.
However, the effect is to generate a master checksum that combines the basehash
and the hashes of the task's dependencies.
</para>
<para>
At the code level, there are a variety of ways both the basehash and the
dependent task hashes can be influenced.
Within the BitBake configuration file, we can give BitBake some extra information
to help it construct the basehash.
The following statement effectively results in a list of global variable
dependency excludes - variables never included in any checksum.
This example uses variables from OpenEmbedded to help illustrate
the concept:
<literallayout class='monospaced'>
BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \
SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL TERM \
USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \
PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \
CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX"
</literallayout>
The previous example excludes the work directory, which is part of
<filename>TMPDIR</filename>.
</para>
<para>
The rules for deciding which hashes of dependent tasks to include through
dependency chains are more complex and are generally accomplished with a
Python function.
The code in <filename>meta/lib/oe/sstatesig.py</filename> shows two examples
of this and also illustrates how you can insert your own policy into the system
if so desired.
This file defines the two basic signature generators OpenEmbedded-Core
uses: "OEBasic" and "OEBasicHash".
By default, there is a dummy "noop" signature handler enabled in BitBake.
This means that behavior is unchanged from previous versions.
<filename>OE-Core</filename> uses the "OEBasicHash" signature handler by default
through this setting in the <filename>bitbake.conf</filename> file:
<literallayout class='monospaced'>
BB_SIGNATURE_HANDLER ?= "OEBasicHash"
</literallayout>
The "OEBasicHash" <filename>BB_SIGNATURE_HANDLER</filename> is the same as the
"OEBasic" version but adds the task hash to the stamp files.
This results in any metadata change that changes the task hash, automatically
causing the task to be run again.
This removes the need to bump
<link linkend='var-bb-PR'><filename>PR</filename></link>
values, and changes to metadata automatically ripple across the build.
</para>
<para>
It is also worth noting that the end result of these signature generators is to
make some dependency and hash information available to the build.
This information includes:
<itemizedlist>
<listitem><para><filename>BB_BASEHASH_task-</filename><replaceable>taskname</replaceable>:
The base hashes for each task in the recipe.
</para></listitem>
<listitem><para><filename>BB_BASEHASH_</filename><replaceable>filename</replaceable><filename>:</filename><replaceable>taskname</replaceable>:
The base hashes for each dependent task.
</para></listitem>
<listitem><para><filename>BBHASHDEPS_</filename><replaceable>filename</replaceable><filename>:</filename><replaceable>taskname</replaceable>:
The task dependencies for each task.
</para></listitem>
<listitem><para><filename>BB_TASKHASH</filename>:
The hash of the currently running task.
</para></listitem>
</itemizedlist>
</para>
<para>
It is worth noting that BitBake's "-S" option lets you
debug Bitbake's processing of signatures.
The options passed to -S allow different debugging modes
to be used, either using BitBake's own debug functions
or possibly those defined in the metadata/signature handler
itself.
The simplest parameter to pass is "none", which causes a
set of signature information to be written out into
<filename>STAMPS_DIR</filename>
corresponding to the targets specified.
The other currently available parameter is "printdiff",
which causes BitBake to try to establish the closest
signature match it can (e.g. in the sstate cache) and then
run <filename>bitbake-diffsigs</filename> over the matches
to determine the stamps and delta where these two
stamp trees diverge.
<note>
It is likely that future versions of BitBake will
provide other signature handlers triggered through
additional "-S" parameters.
</note>
</para>
<para>
You can find more information on checksum metadata in the
"<link linkend='task-checksums-and-setscene'>Task Checksums and Setscene</link>"
section.
</para>
</section>
<section id='setscene'>
<title>Setscene</title>
<para>
The setscene process enables BitBake to handle "pre-built" artifacts.
The ability to handle and reuse these artifacts allows BitBake
the luxury of not having to build something from scratch every time.
Instead, BitBake can use, when possible, existing build artifacts.
</para>
<para>
BitBake needs to have reliable data indicating whether or not an
artifact is compatible.
Signatures, described in the previous section, provide an ideal
way of representing whether an artifact is compatible.
If a signature is the same, an object can be reused.
</para>
<para>
If an object can be reused, the problem then becomes how to
replace a given task or set of tasks with the pre-built artifact.
BitBake solves the problem with the "setscene" process.
</para>
<para>
When BitBake is asked to build a given target, before building anything,
it first asks whether cached information is available for any of the
targets it's building, or any of the intermediate targets.
If cached information is available, BitBake uses this information instead of
running the main tasks.
</para>
<para>
BitBake first calls the function defined by the
<link linkend='var-bb-BB_HASHCHECK_FUNCTION'><filename>BB_HASHCHECK_FUNCTION</filename></link>
variable with a list of tasks and corresponding
hashes it wants to build.
This function is designed to be fast and returns a list
of the tasks for which it believes in can obtain artifacts.
</para>
<para>
Next, for each of the tasks that were returned as possibilities,
BitBake executes a setscene version of the task that the possible
artifact covers.
Setscene versions of a task have the string "_setscene" appended to the
task name.
So, for example, the task with the name <filename>xxx</filename> has
a setscene task named <filename>xxx_setscene</filename>.
The setscene version of the task executes and provides the necessary
artifacts returning either success or failure.
</para>
<para>
As previously mentioned, an artifact can cover more than one task.
For example, it is pointless to obtain a compiler if you
already have the compiled binary.
To handle this, BitBake calls the
<link linkend='var-bb-BB_SETSCENE_DEPVALID'><filename>BB_SETSCENE_DEPVALID</filename></link>
function for each successful setscene task to know whether or not it needs
to obtain the dependencies of that task.
</para>
<para>
Finally, after all the setscene tasks have executed, BitBake calls the
function listed in
<link linkend='var-bb-BB_SETSCENE_VERIFY_FUNCTION2'><filename>BB_SETSCENE_VERIFY_FUNCTION2</filename></link>
with the list of tasks BitBake thinks has been "covered".
The metadata can then ensure that this list is correct and can
inform BitBake that it wants specific tasks to be run regardless
of the setscene result.
</para>
<para>
You can find more information on setscene metadata in the
"<link linkend='task-checksums-and-setscene'>Task Checksums and Setscene</link>"

<para>
BitBake's fetch module is a standalone piece of library code
that deals with the intricacies of downloading source code
and files from remote systems.
Fetching source code is one of the cornerstones of building software.
As such, this module forms an important part of BitBake.
</para>
<para>
The current fetch module is called "fetch2" and refers to the
fact that it is the second major version of the API.
The original version is obsolete and has been removed from the codebase.
Thus, in all cases, "fetch" refers to "fetch2" in this
manual.
</para>
<section id='the-download-fetch'>
<title>The Download (Fetch)</title>
<para>
BitBake takes several steps when fetching source code or files.
The fetcher codebase deals with two distinct processes in order:
obtaining the files from somewhere (cached or otherwise)
and then unpacking those files into a specific location and
perhaps in a specific way.
Getting and unpacking the files is often optionally followed
by patching.
Patching, however, is not covered by this module.
</para>
<para>
The code to execute the first part of this process, a fetch,
looks something like the following:
<literallayout class='monospaced'>
src_uri = (d.getVar('SRC_URI') or "").split()
fetcher = bb.fetch2.Fetch(src_uri, d)
fetcher.download()
</literallayout>
This code sets up an instance of the fetch class.
The instance uses a space-separated list of URLs from the
<link linkend='var-bb-SRC_URI'><filename>SRC_URI</filename></link>
variable and then calls the <filename>download</filename>
method to download the files.
</para>
<para>
The instantiation of the fetch class is usually followed by:
<literallayout class='monospaced'>
rootdir = l.getVar('WORKDIR')
fetcher.unpack(rootdir)
</literallayout>
This code unpacks the downloaded files to the
specified by <filename>WORKDIR</filename>.
<note>
For convenience, the naming in these examples matches
the variables used by OpenEmbedded.
If you want to see the above code in action, examine
the OpenEmbedded class file <filename>base.bbclass</filename>.
</note>
The <filename>SRC_URI</filename> and <filename>WORKDIR</filename>
variables are not hardcoded into the fetcher, since those fetcher
methods can be (and are) called with different variable names.
In OpenEmbedded for example, the shared state (sstate) code uses
the fetch module to fetch the sstate files.
</para>
<para>
When the <filename>download()</filename> method is called,
BitBake tries to resolve the URLs by looking for source files
in a specific search order:
<itemizedlist>
<listitem><para><emphasis>Pre-mirror Sites:</emphasis>
BitBake first uses pre-mirrors to try and find source files.
These locations are defined using the
<link linkend='var-bb-PREMIRRORS'><filename>PREMIRRORS</filename></link>
variable.
</para></listitem>
<listitem><para><emphasis>Source URI:</emphasis>
If pre-mirrors fail, BitBake uses the original URL (e.g from
<filename>SRC_URI</filename>).
</para></listitem>
<listitem><para><emphasis>Mirror Sites:</emphasis>
If fetch failures occur, BitBake next uses mirror locations as
defined by the
<link linkend='var-bb-MIRRORS'><filename>MIRRORS</filename></link>
variable.
</para></listitem>
</itemizedlist>
</para>
<para>
For each URL passed to the fetcher, the fetcher
calls the submodule that handles that particular URL type.
This behavior can be the source of some confusion when you
are providing URLs for the <filename>SRC_URI</filename>
variable.
Consider the following two URLs:
<literallayout class='monospaced'>
http://git.yoctoproject.org/git/poky;protocol=git
git://git.yoctoproject.org/git/poky;protocol=http
</literallayout>
In the former case, the URL is passed to the
<filename>wget</filename> fetcher, which does not
understand "git".
Therefore, the latter case is the correct form since the
Git fetcher does know how to use HTTP as a transport.
</para>
<para>
Here are some examples that show commonly used mirror
definitions:
<literallayout class='monospaced'>
PREMIRRORS ?= "\
bzr://.*/.* http://somemirror.org/sources/ \n \
cvs://.*/.* http://somemirror.org/sources/ \n \
git://.*/.* http://somemirror.org/sources/ \n \
hg://.*/.* http://somemirror.org/sources/ \n \
osc://.*/.* http://somemirror.org/sources/ \n \
p4://.*/.* http://somemirror.org/sources/ \n \
svn://.*/.* http://somemirror.org/sources/ \n"
MIRRORS =+ "\
ftp://.*/.* http://somemirror.org/sources/ \n \
http://.*/.* http://somemirror.org/sources/ \n \
https://.*/.* http://somemirror.org/sources/ \n"
</literallayout>
It is useful to note that BitBake supports
cross-URLs.
It is possible to mirror a Git repository on an HTTP
server as a tarball.
This is what the <filename>git://</filename> mapping in
the previous example does.
</para>
<para>
Since network accesses are slow, Bitbake maintains a
cache of files downloaded from the network.
Any source files that are not local (i.e.
downloaded from the Internet) are placed into the download
directory, which is specified by the
<link linkend='var-bb-DL_DIR'><filename>DL_DIR</filename></link>
variable.
</para>
<para>
File integrity is of key importance for reproducing builds.
For non-local archive downloads, the fetcher code can verify
SHA-256 and MD5 checksums to ensure the archives have been
downloaded correctly.
You can specify these checksums by using the
<filename>SRC_URI</filename> variable with the appropriate
varflags as follows:
<literallayout class='monospaced'>
SRC_URI[md5sum] = "<replaceable>value</replaceable>"
SRC_URI[sha256sum] = "<replaceable>value</replaceable>"
</literallayout>
You can also specify the checksums as parameters on the
<filename>SRC_URI</filename> as shown below:
<literallayout class='monospaced'>
SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
</literallayout>
If multiple URIs exist, you can specify the checksums either
directly as in the previous example, or you can name the URLs.
The following syntax shows how you name the URIs:
<literallayout class='monospaced'>
SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
</literallayout>
After a file has been downloaded and has had its checksum checked,
a ".done" stamp is placed in <filename>DL_DIR</filename>.
BitBake uses this stamp during subsequent builds to avoid
downloading or comparing a checksum for the file again.
<note>
It is assumed that local storage is safe from data corruption.
If this were not the case, there would be bigger issues to worry about.
</note>
</para>
<para>
If
<link linkend='var-bb-BB_STRICT_CHECKSUM'><filename>BB_STRICT_CHECKSUM</filename></link>
is set, any download without a checksum triggers an
error message.
The
<link linkend='var-bb-BB_NO_NETWORK'><filename>BB_NO_NETWORK</filename></link>
variable can be used to make any attempted network access a fatal
error, which is useful for checking that mirrors are complete
as well as other things.
</para>
</section>
<section id='bb-the-unpack'>
<title>The Unpack</title>
<para>
The unpack process usually immediately follows the download.
For all URLs except Git URLs, BitBake uses the common
<filename>unpack</filename> method.
</para>
<para>
A number of parameters exist that you can specify within the
URL to govern the behavior of the unpack stage:
<itemizedlist>
<listitem><para><emphasis>unpack:</emphasis>
Controls whether the URL components are unpacked.
If set to "1", which is the default, the components
are unpacked.
If set to "0", the unpack stage leaves the file alone.
This parameter is useful when you want an archive to be
copied in and not be unpacked.
</para></listitem>
<listitem><para><emphasis>dos:</emphasis>
Applies to <filename>.zip</filename> and
<filename>.jar</filename> files and specifies whether to
use DOS line ending conversion on text files.
</para></listitem>
<listitem><para><emphasis>basepath:</emphasis>
Instructs the unpack stage to strip the specified
directories from the source path when unpacking.
</para></listitem>
<listitem><para><emphasis>subdir:</emphasis>
Unpacks the specific URL to the specified subdirectory
within the root directory.
</para></listitem>
</itemizedlist>
The unpack call automatically decompresses and extracts files
with ".Z", ".z", ".gz", ".xz", ".zip", ".jar", ".ipk", ".rpm".
".srpm", ".deb" and ".bz2" extensions as well as various combinations
of tarball extensions.
</para>
<para>
As mentioned, the Git fetcher has its own unpack method that
is optimized to work with Git trees.
Basically, this method works by cloning the tree into the final
directory.
The process is completed using references so that there is
only one central copy of the Git metadata needed.
</para>
</section>
<section id='bb-fetchers'>
<title>Fetchers</title>
<para>
As mentioned earlier, the URL prefix determines which
fetcher submodule BitBake uses.
Each submodule can support different URL parameters,
which are described in the following sections.
</para>
<section id='local-file-fetcher'>
<title>Local file fetcher (<filename>file://</filename>)</title>
<para>
This submodule handles URLs that begin with
<filename>file://</filename>.
The filename you specify within the URL can be
either an absolute or relative path to a file.
If the filename is relative, the contents of the
<link linkend='var-bb-FILESPATH'><filename>FILESPATH</filename></link>
variable is used in the same way
<filename>PATH</filename> is used to find executables.
If the file cannot be found, it is assumed that it is available in
<link linkend='var-bb-DL_DIR'><filename>DL_DIR</filename></link>
by the time the <filename>download()</filename> method is called.
</para>
<para>
If you specify a directory, the entire directory is
unpacked.
</para>
<para>
Here are a couple of example URLs, the first relative and
the second absolute:
<literallayout class='monospaced'>
SRC_URI = "file://relativefile.patch"
SRC_URI = "file:///Users/ich/very_important_software"
</literallayout>
</para>
</section>
<section id='http-ftp-fetcher'>
<title>HTTP/FTP wget fetcher (<filename>http://</filename>, <filename>ftp://</filename>, <filename>https://</filename>)</title>
<para>
This fetcher obtains files from web and FTP servers.
Internally, the fetcher uses the wget utility.
</para>
<para>
The executable and parameters used are specified by the
<filename>FETCHCMD_wget</filename> variable, which defaults
to sensible values.
The fetcher supports a parameter "downloadfilename" that
allows the name of the downloaded file to be specified.
Specifying the name of the downloaded file is useful
for avoiding collisions in
<link linkend='var-bb-DL_DIR'><filename>DL_DIR</filename></link>
when dealing with multiple files that have the same name.
</para>
<para>
Some example URLs are as follows:
<literallayout class='monospaced'>
SRC_URI = "http://oe.handhelds.org/not_there.aac"
SRC_URI = "ftp://oe.handhelds.org/not_there_as_well.aac"
SRC_URI = "ftp://you@oe.handhelds.org/home/you/secret.plan"
</literallayout>
</para>
<note>
Because URL parameters are delimited by semi-colons, this can
introduce ambiguity when parsing URLs that also contain semi-colons,
for example:
<literallayout class='monospaced'>
SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47"
</literallayout>
Such URLs should should be modified by replacing semi-colons with '&amp;' characters:
<literallayout class='monospaced'>
SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47"
</literallayout>
In most cases this should work. Treating semi-colons and '&amp;' in queries
identically is recommended by the World Wide Web Consortium (W3C).
Note that due to the nature of the URL, you may have to specify the name
of the downloaded file as well:
<literallayout class='monospaced'>
SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47;downloadfilename=myfile.bz2"
</literallayout>

</para>
<para>
The supported parameters are as follows:
<itemizedlist>
<listitem><para><emphasis>"method":</emphasis>
The protocol over which to communicate with the CVS
server.
By default, this protocol is "pserver".
If "method" is set to "ext", BitBake examines the
"rsh" parameter and sets <filename>CVS_RSH</filename>.
You can use "dir" for local directories.
</para></listitem>
<listitem><para><emphasis>"module":</emphasis>
Specifies the module to check out.
You must supply this parameter.

<section id='git-fetcher'>
<title>Git Fetcher (<filename>git://</filename>)</title>
<para>
This fetcher submodule fetches code from the Git
source control system.
The fetcher works by creating a bare clone of the
remote into
<link linkend='var-bb-GITDIR'><filename>GITDIR</filename></link>,
which is usually <filename>DL_DIR/git2</filename>.
This bare clone is then cloned into the work directory during the
unpack stage when a specific tree is checked out.
This is done using alternates and by reference to
minimize the amount of duplicate data on the disk and
make the unpack process fast.
The executable used can be set with
<filename>FETCHCMD_git</filename>.
</para>
<para>
This fetcher supports the following parameters:
<itemizedlist>
<listitem><para><emphasis>"protocol":</emphasis>
The protocol used to fetch the files.
The default is "git" when a hostname is set.
If a hostname is not set, the Git protocol is "file".
You can also use "http", "https", "ssh" and "rsync".
</para></listitem>
<listitem><para><emphasis>"nocheckout":</emphasis>
Tells the fetcher to not checkout source code when
unpacking when set to "1".
Set this option for the URL where there is a custom
routine to checkout code.
The default is "0".
</para></listitem>
<listitem><para><emphasis>"rebaseable":</emphasis>
Indicates that the upstream Git repository can be rebased.
You should set this parameter to "1" if
revisions can become detached from branches.
In this case, the source mirror tarball is done per
revision, which has a loss of efficiency.
Rebasing the upstream Git repository could cause the
current revision to disappear from the upstream repository.
This option reminds the fetcher to preserve the local cache
carefully for future use.
The default value for this parameter is "0".
</para></listitem>
<listitem><para><emphasis>"nobranch":</emphasis>
Tells the fetcher to not check the SHA validation
for the branch when set to "1".
The default is "0".
Set this option for the recipe that refers to
the commit that is valid for a tag instead of
the branch.
</para></listitem>
<listitem><para><emphasis>"bareclone":</emphasis>
Tells the fetcher to clone a bare clone into the
destination directory without checking out a working tree.
Only the raw Git metadata is provided.
This parameter implies the "nocheckout" parameter as well.
</para></listitem>
<listitem><para><emphasis>"branch":</emphasis>
The branch(es) of the Git tree to clone.
If unset, this is assumed to be "master".
The number of branch parameters much match the number of

<listitem><para><emphasis>"tag":</emphasis>
Specifies a tag to use for the checkout.
To correctly resolve tags, BitBake must access the

For that reason, tags are often not used.
As far as Git is concerned, the "tag" parameter behaves
effectively the same as the "rev" parameter.

repository.
</para>
<para>
To use this fetcher, make sure your recipe has proper
<link linkend='var-bb-SRC_URI'><filename>SRC_URI</filename></link>,
<link linkend='var-bb-SRCREV'><filename>SRCREV</filename></link>, and
<link linkend='var-bb-PV'><filename>PV</filename></link> settings.
Here is an example:
<literallayout class='monospaced'>

SRCREV = "EXAMPLE_CLEARCASE_TAG"
PV = "${@d.getVar("SRCREV", False).replace("/", "+")}"
</literallayout>
The fetcher uses the <filename>rcleartool</filename> or
<filename>cleartool</filename> remote client, depending on
which one is available.
</para>
<para>
Following are options for the <filename>SRC_URI</filename>
statement:
<itemizedlist>
<listitem><para><emphasis><filename>vob</filename></emphasis>:
The name, which must include the
prepending "/" character, of the ClearCase VOB.

prepending "/" character, in the selected VOB.
<note>
The <filename>module</filename> and <filename>vob</filename>
options are combined to create the <filename>load</filename> rule in
the view config spec.
As an example, consider the <filename>vob</filename> and
<filename>module</filename> values from the
<filename>SRC_URI</filename> statement at the start of this section.
Combining those values results in the following:
<literallayout class='monospaced'>

<para>
By default, the fetcher creates a configuration specification.
If you want this specification written to an area other than the default,
use the <filename>CCASE_CUSTOM_CONFIG_SPEC</filename> variable
in your recipe to define where the specification is written.
<note>
the <filename>SRCREV</filename> loses its functionality if you
specify this variable.
However, <filename>SRCREV</filename> is still used to label the
archive after a fetch even though it does not define what is
fetched.

order to define the Perforce server URL and port, username, and
password if you do not wish to keep those values in a recipe
itself.
If you choose not to use <filename>P4CONFIG</filename>,

<title>BitBake Hello World</title>
<para>
The simplest example commonly used to demonstrate any new
programming language or tool is the
"<ulink url="http://en.wikipedia.org/wiki/Hello_world_program">Hello World</ulink>"

This appendix demonstrates, in tutorial form, Hello
World within the context of BitBake.
The tutorial describes how to create a new project
and the applicable metadata files necessary to allow
BitBake to build it.

<title>Setting Up the BitBake Environment</title>
<para>
First, you need to be sure that you can run BitBake.
Set your working directory to where your local BitBake
files are and run the following command:
<literallayout class='monospaced'>
$ ./bin/bitbake --version
BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0
</literallayout>
The console output tells you what version you are running.
</para>
<para>
The recommended method to run BitBake is from a directory of your
choice.
To be able to run BitBake from any directory, you need to add the
executable binary to your binary to your shell's environment
<filename>PATH</filename> variable.
First, look at your current <filename>PATH</filename> variable
by entering the following:
<literallayout class='monospaced'>
$ echo $PATH
</literallayout>
Next, add the directory location for the BitBake binary to the
<filename>PATH</filename>.
Here is an example that adds the
<filename>/home/scott-lenovo/bitbake/bin</filename> directory
to the front of the <filename>PATH</filename> variable:
<literallayout class='monospaced'>
$ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
</literallayout>
You should now be able to enter the <filename>bitbake</filename>
command from the command line while working from any directory.

<section id='the-hello-world-example'>
<title>The Hello World Example</title>
<para>
The overall goal of this exercise is to build a
complete "Hello World" example utilizing task and layer
concepts.
Because this is how modern projects such as OpenEmbedded and
the Yocto Project utilize BitBake, the example
provides an excellent starting point for understanding
BitBake.
</para>
<para>
To help you understand how to use BitBake to build targets,
the example starts with nothing but the <filename>bitbake</filename>
command, which causes BitBake to fail and report problems.
The example progresses by adding pieces to the build to
eventually conclude with a working, minimal "Hello World"
example.
</para>
<para>
While every attempt is made to explain what is happening during
the example, the descriptions cannot cover everything.
You can find further information throughout this manual.
Also, you can actively participate in the
<ulink url='http://lists.openembedded.org/mailman/listinfo/bitbake-devel'></ulink>
discussion mailing list about the BitBake build tool.
</para>
<note>
This example was inspired by and drew heavily from
<ulink url="http://www.mail-archive.com/yocto@yoctoproject.org/msg09379.html">Mailing List post - The BitBake equivalent of "Hello, World!"</ulink>.
</note>
<para>
As stated earlier, the goal of this example
is to eventually compile "Hello World".
However, it is unknown what BitBake needs and what you have
to provide in order to achieve that goal.
Recall that BitBake utilizes three types of metadata files:
<link linkend='configuration-files'>Configuration Files</link>,
<link linkend='classes'>Classes</link>, and
<link linkend='recipes'>Recipes</link>.
But where do they go?
How does BitBake find them?
BitBake's error messaging helps you answer these types of questions
and helps you better understand exactly what is going on.
</para>
<para>
Following is the complete "Hello World" example.
</para>
<orderedlist>
<listitem><para><emphasis>Create a Project Directory:</emphasis>
First, set up a directory for the "Hello World" project.
Here is how you can do so in your home directory:
<literallayout class='monospaced'>
$ mkdir ~/hello
$ cd ~/hello
</literallayout>
This is the directory that BitBake will use to do all of
its work.
You can use this directory to keep all the metafiles needed
by BitBake.
Having a project directory is a good way to isolate your
project.
</para></listitem>
<listitem><para><emphasis>Run Bitbake:</emphasis>
At this point, you have nothing but a project directory.
Run the <filename>bitbake</filename> command and see what
it does:
<literallayout class='monospaced'>
$ bitbake
The BBPATH variable is not set and bitbake did not
find a conf/bblayers.conf file in the expected location.
Maybe you accidentally invoked bitbake from the wrong directory?
DEBUG: Removed the following variables from the environment:
GNOME_DESKTOP_SESSION_ID, XDG_CURRENT_DESKTOP,
GNOME_KEYRING_CONTROL, DISPLAY, SSH_AGENT_PID, LANG, no_proxy,
XDG_SESSION_PATH, XAUTHORITY, SESSION_MANAGER, SHLVL,
MANDATORY_PATH, COMPIZ_CONFIG_PROFILE, WINDOWID, EDITOR,
GPG_AGENT_INFO, SSH_AUTH_SOCK, GDMSESSION, GNOME_KEYRING_PID,
XDG_SEAT_PATH, XDG_CONFIG_DIRS, LESSOPEN, DBUS_SESSION_BUS_ADDRESS,
_, XDG_SESSION_COOKIE, DESKTOP_SESSION, LESSCLOSE, DEFAULTS_PATH,
UBUNTU_MENUPROXY, OLDPWD, XDG_DATA_DIRS, COLORTERM, LS_COLORS
</literallayout>
The majority of this output is specific to environment variables
that are not directly relevant to BitBake.
However, the very first message regarding the
<filename>BBPATH</filename> variable and the
<filename>conf/bblayers.conf</filename> file
is relevant.</para>
<para>
When you run BitBake, it begins looking for metadata files.
The
<link linkend='var-bb-BBPATH'><filename>BBPATH</filename></link>
variable is what tells BitBake where to look for those files.
<filename>BBPATH</filename> is not set and you need to set it.
Without <filename>BBPATH</filename>, Bitbake cannot
find any configuration files (<filename>.conf</filename>)
or recipe files (<filename>.bb</filename>) at all.
BitBake also cannot find the <filename>bitbake.conf</filename>
file.
</para></listitem>
<listitem><para><emphasis>Setting <filename>BBPATH</filename>:</emphasis>
For this example, you can set <filename>BBPATH</filename>
in the same manner that you set <filename>PATH</filename>
earlier in the appendix.
You should realize, though, that it is much more flexible to set the
<filename>BBPATH</filename> variable up in a configuration
file for each project.</para>
<para>From your shell, enter the following commands to set and
export the <filename>BBPATH</filename> variable:
<literallayout class='monospaced'>
$ BBPATH="<replaceable>projectdirectory</replaceable>"
$ export BBPATH
</literallayout>
Use your actual project directory in the command.
BitBake uses that directory to find the metadata it needs for
your project.
<note>
When specifying your project directory, do not use the
tilde ("~") character as BitBake does not expand that character
as the shell would.
</note>
</para></listitem>
<listitem><para><emphasis>Run Bitbake:</emphasis>
Now that you have <filename>BBPATH</filename> defined, run
the <filename>bitbake</filename> command again:
<literallayout class='monospaced'>
$ bitbake

This sample output shows that BitBake could not find the
<filename>conf/bitbake.conf</filename> file in the project
directory.
This file is the first thing BitBake must find in order
to build a target.
And, since the project directory for this example is
empty, you need to provide a <filename>conf/bitbake.conf</filename>
file.
</para></listitem>
<listitem><para><emphasis>Creating <filename>conf/bitbake.conf</filename>:</emphasis>
The <filename>conf/bitbake.conf</filename> includes a number of
configuration variables BitBake uses for metadata and recipe
files.
For this example, you need to create the file in your project directory
and define some key BitBake variables.
For more information on the <filename>bitbake.conf</filename> file,
see
<ulink url='http://git.openembedded.org/bitbake/tree/conf/bitbake.conf'></ulink>.
</para>
<para>Use the following commands to create the <filename>conf</filename>
directory in the project directory:
<literallayout class='monospaced'>
$ mkdir conf
</literallayout>
From within the <filename>conf</filename> directory, use
some editor to create the <filename>bitbake.conf</filename>
so that it contains the following:
<literallayout class='monospaced'>
<link linkend='var-bb-PN'>PN</link> = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"

<link linkend='var-bb-T'>T</link> = "${TMPDIR}/${PN}/work"
<link linkend='var-bb-B'>B</link> = "${TMPDIR}/${PN}"
</literallayout>
<note>
Without a value for <filename>PN</filename>, the
variables <filename>STAMP</filename>,
<filename>T</filename>, and <filename>B</filename>,
prevent more than one recipe from working. You can fix
this by either setting <filename>PN</filename> to have
a value similar to what OpenEmbedded and BitBake use
in the default <filename>bitbake.conf</filename> file
(see previous example). Or, by manually updating each
recipe to set <filename>PN</filename>. You will also
need to include <filename>PN</filename> as part of the
<filename>STAMP</filename>, <filename>T</filename>, and
<filename>B</filename> variable definitions in the
<filename>local.conf</filename> file.
</note>
The <filename>TMPDIR</filename> variable establishes a directory
that BitBake uses for build output and intermediate files other
than the cached information used by the
<link linkend='setscene'>Setscene</link> process.
Here, the <filename>TMPDIR</filename> directory is set to
<filename>hello/tmp</filename>.
<note><title>Tip</title>
You can always safely delete the <filename>tmp</filename>
directory in order to rebuild a BitBake target.
The build process creates the directory for you
when you run BitBake.

</para></listitem>
<listitem><para><emphasis>Creating <filename>classes/base.bbclass</filename>:</emphasis>
BitBake uses class files to provide common code and functionality.
The minimally required class for BitBake is the
<filename>classes/base.bbclass</filename> file.
The <filename>base</filename> class is implicitly inherited by
every recipe.
BitBake looks for the class in the <filename>classes</filename>
directory of the project (i.e <filename>hello/classes</filename>
in this example).
</para>
<para>Create the <filename>classes</filename> directory as follows:
<literallayout class='monospaced'>

Move to the <filename>classes</filename> directory and then
create the <filename>base.bbclass</filename> file by inserting
this single line:
<literallayout class='monospaced'>
addtask build
</literallayout>
The minimal task that BitBake runs is the
<filename>do_build</filename> task.
This is all the example needs in order to build the project.
Of course, the <filename>base.bbclass</filename> can have much
more depending on which build environments BitBake is
supporting.
</para></listitem>
<listitem><para><emphasis>Run Bitbake:</emphasis>

Nothing to do. Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information.
</literallayout>
BitBake is finally reporting no errors.
However, you can see that it really does not have anything
to do.
You need to create a recipe that gives BitBake something to do.
</para></listitem>
<listitem><para><emphasis>Creating a Layer:</emphasis>
While it is not really necessary for such a small example,
it is good practice to create a layer in which to keep your
code separate from the general metadata used by BitBake.
Thus, this example creates and uses a layer called "mylayer".
<note>
You can find additional information on layers in the
"<link linkend='layers'>Layers</link>" section.
</note></para>
<para>Minimally, you need a recipe file and a layer configuration
file in your layer.
The configuration file needs to be in the <filename>conf</filename>
directory inside the layer.
Use these commands to set up the layer and the <filename>conf</filename>
directory:
<literallayout class='monospaced'>
$ cd $HOME
$ mkdir mylayer
$ cd mylayer
$ mkdir conf
</literallayout>
Move to the <filename>conf</filename> directory and create a
<filename>layer.conf</filename> file that has the following:
<literallayout class='monospaced'>
BBPATH .= ":${<link linkend='var-bb-LAYERDIR'>LAYERDIR</link>}"
<link linkend='var-bb-BBFILES'>BBFILES</link> += "${LAYERDIR}/*.bb"
<link linkend='var-bb-BBFILE_COLLECTIONS'>BBFILE_COLLECTIONS</link> += "mylayer"
<link linkend='var-bb-BBFILE_PATTERN'>BBFILE_PATTERN_mylayer</link> := "^${LAYERDIR_RE}/"
</literallayout>
For information on these variables, click the links
to go to the definitions in the glossary.</para>
<para>You need to create the recipe file next.
Inside your layer at the top-level, use an editor and create
a recipe file named <filename>printhello.bb</filename> that
has the following:
<literallayout class='monospaced'>
<link linkend='var-bb-DESCRIPTION'>DESCRIPTION</link> = "Prints Hello World"
<link linkend='var-bb-PN'>PN</link> = 'printhello'
<link linkend='var-bb-PV'>PV</link> = '1'
python do_build() {
bb.plain("********************");
bb.plain("* *");
bb.plain("* Hello, World! *");
bb.plain("* *");
bb.plain("********************");
}
</literallayout>
The recipe file simply provides a description of the
recipe, the name, version, and the <filename>do_build</filename>
task, which prints out "Hello World" to the console.

BitBake finds the <filename>printhello</filename> recipe and
successfully runs the task.
<note>
After the first execution, re-running
<filename>bitbake printhello</filename> again will not
result in a BitBake run that prints the same console
output.
The reason for this is that the first time the
<filename>printhello.bb</filename> recipe's
<filename>do_build</filename> task executes
successfully, BitBake writes a stamp file for the task.
Thus, the next time you attempt to run the task
using that same <filename>bitbake</filename> command,
BitBake notices the stamp and therefore determines
that the task does not need to be re-run.
If you delete the <filename>tmp</filename> directory
or run <filename>bitbake -c clean printhello</filename>
and then re-run the build, the "Hello, World!" message will
be printed again.

<title>Overview</title>
<para>
Welcome to the BitBake User Manual.
This manual provides information on the BitBake tool.
The information attempts to be as independent as possible regarding
systems that use BitBake, such as OpenEmbedded and the
Yocto Project.
In some cases, scenarios or examples within the context of
a build system are used in the manual to help with understanding.
For these cases, the manual clearly states the context.

<section id="intro">
<title>Introduction</title>
<para>
Fundamentally, BitBake is a generic task execution
engine that allows shell and Python tasks to be run
efficiently and in parallel while working within
complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core
and builds embedded Linux software stacks using
a task-oriented approach.
</para>
<para>
Conceptually, BitBake is similar to GNU Make in
some regards but has significant differences:
<itemizedlist>
<listitem><para>
BitBake executes tasks according to provided
metadata that builds up the tasks.
Metadata is stored in recipe (<filename>.bb</filename>)
and related recipe "append" (<filename>.bbappend</filename>)
files, configuration (<filename>.conf</filename>) and
underlying include (<filename>.inc</filename>) files, and
in class (<filename>.bbclass</filename>) files.
The metadata provides
BitBake with instructions on what tasks to run and
the dependencies between those tasks.
</para></listitem>
<listitem><para>
BitBake includes a fetcher library for obtaining source
code from various places such as local files, source control
systems, or websites.
</para></listitem>
<listitem><para>
The instructions for each unit to be built (e.g. a piece
of software) are known as "recipe" files and
contain all the information about the unit
(dependencies, source file locations, checksums, description
and so on).
</para></listitem>
<listitem><para>
BitBake includes a client/server abstraction and can
be used from a command line or used as a service over
XML-RPC and has several different user interfaces.

<title>History and Goals</title>

BitBake was originally a part of the OpenEmbedded project.
It was inspired by the Portage package management system
used by the Gentoo Linux distribution.
On December 7, 2004, OpenEmbedded project team member
Chris Larson split the project into two distinct pieces:

</itemizedlist>
Today, BitBake is the primary basis of the
<ulink url="http://www.openembedded.org/">OpenEmbedded</ulink>
project, which is being used to build and maintain Linux
distributions such as the
<ulink url='http://www.angstrom-distribution.org/'>Angstrom Distribution</ulink>,
and which is also being used as the build tool for Linux projects
such as the
<ulink url='http://www.yoctoproject.org'>Yocto Project</ulink>.
</para>
<para>
Prior to BitBake, no other build tool adequately met the needs of
an aspiring embedded Linux distribution.
All of the build systems used by traditional desktop Linux
distributions lacked important functionality, and none of the
ad hoc Buildroot-based systems, prevalent in the
embedded space, were scalable or maintainable.
</para>
<para>
Some important original goals for BitBake were:
<itemizedlist>
<listitem><para>
Handle cross-compilation.
</para></listitem>
<listitem><para>
Handle inter-package dependencies (build time on
target architecture, build time on native
architecture, and runtime).
</para></listitem>
<listitem><para>
Support running any number of tasks within a given
package, including, but not limited to, fetching
upstream sources, unpacking them, patching them,
configuring them, and so forth.
</para></listitem>
<listitem><para>
Be Linux distribution agnostic for both build and
target systems.
</para></listitem>
<listitem><para>
Be architecture agnostic.
</para></listitem>

Support multiple build and target operating systems
(e.g. Cygwin, the BSDs, and so forth).

<listitem><para>
Be self contained, rather than tightly

projects for their builds.
</para></listitem>
<listitem><para>
Provide an inheritance mechanism to share
common metadata between many packages.
</para></listitem>
</itemizedlist>
Over time it became apparent that some further requirements
were necessary:
<itemizedlist>
<listitem><para>
Handle variants of a base recipe (e.g. native, sdk,
and multilib).
</para></listitem>
<listitem><para>
Split metadata into layers and allow layers
to enhance or override other layers.
</para></listitem>
<listitem><para>
Allow representation of a given set of input variables
to a task as a checksum.
Based on that checksum, allow acceleration of builds
with prebuilt components.
</para></listitem>
</itemizedlist>
BitBake satisfies all the original requirements and many more
with extensions being made to the basic functionality to
reflect the additional requirements.
Flexibility and power have always been the priorities.
BitBake is highly extensible and supports embedded Python code and
execution of any arbitrary tasks.
</para>
</section>
<section id="Concepts">
<title>Concepts</title>
<para>
BitBake is a program written in the Python language.
At the highest level, BitBake interprets metadata, decides
what tasks are required to run, and executes those tasks.
Similar to GNU Make, BitBake controls how software is
built.
GNU Make achieves its control through "makefiles", while
BitBake uses "recipes".
</para>
<para>
BitBake extends the capabilities of a simple
tool like GNU Make by allowing for the definition of much more
complex tasks, such as assembling entire embedded Linux
distributions.
</para>
<para>
The remainder of this section introduces several concepts
that should be understood in order to better leverage
the power of BitBake.
</para>
<section id='recipes'>
<title>Recipes</title>
<para>
BitBake Recipes, which are denoted by the file extension
<filename>.bb</filename>, are the most basic metadata files.
These recipe files provide BitBake with the following:
<itemizedlist>
<listitem><para>Descriptive information about the
package (author, homepage, license, and so on)</para></listitem>
<listitem><para>The version of the recipe</para></listitem>
<listitem><para>Existing dependencies (both build
and runtime dependencies)</para></listitem>
<listitem><para>Where the source code resides and
how to fetch it</para></listitem>
<listitem><para>Whether the source code requires
any patches, where to find them, and how to apply
them</para></listitem>
<listitem><para>How to configure and compile the
source code</para></listitem>
<listitem><para>Where on the target machine to install the
package or packages created</para></listitem>
</itemizedlist>
</para>
<para>
Within the context of BitBake, or any project utilizing BitBake
as its build system, files with the <filename>.bb</filename>
extension are referred to as recipes.
<note>
The term "package" is also commonly used to describe recipes.
However, since the same word is used to describe packaged
output from a project, it is best to maintain a single
descriptive term - "recipes".
Put another way, a single "recipe" file is quite capable
of generating a number of related but separately installable
"packages".
In fact, that ability is fairly common.
</note>
</para>
</section>
<section id='configuration-files'>
<title>Configuration Files</title>
<para>
Configuration files, which are denoted by the
<filename>.conf</filename> extension, define
various configuration variables that govern the project's build
process.
These files fall into several areas that define
machine configuration options, distribution configuration
options, compiler tuning options, general common
configuration options, and user configuration options.
The main configuration file is the sample
<filename>bitbake.conf</filename> file, which is
located within the BitBake source tree
<filename>conf</filename> directory.
</para>
</section>
<section id='classes'>
<title>Classes</title>
<para>
Class files, which are denoted by the
<filename>.bbclass</filename> extension, contain
information that is useful to share between metadata files.
The BitBake source tree currently comes with one class metadata file
called <filename>base.bbclass</filename>.
You can find this file in the
<filename>classes</filename> directory.
The <filename>base.bbclass</filename> class files is special since it
is always included automatically for all recipes
and classes.
This class contains definitions for standard basic tasks such
as fetching, unpacking, configuring (empty by default),
compiling (runs any Makefile present), installing (empty by
default) and packaging (empty by default).
These tasks are often overridden or extended by other classes
added during the project development process.
</para>
</section>
<section id='layers'>
<title>Layers</title>
<para>
Layers allow you to isolate different types of
customizations from each other.
While you might find it tempting to keep everything in one layer
when working on a single project, the more modular you organize
your metadata, the easier it is to cope with future changes.
</para>
<para>
To illustrate how you can use layers to keep things modular,
consider customizations you might make to support a specific target machine.
These types of customizations typically reside in a special layer,
rather than a general layer, called a Board Support Package (BSP)
Layer.
Furthermore, the machine customizations should be isolated from
recipes and metadata that support a new GUI environment, for
example.
This situation gives you a couple of layers: one for the machine
configurations and one for the GUI environment.
It is important to understand, however, that the BSP layer can still
make machine-specific additions to recipes within
the GUI environment layer without polluting the GUI layer itself
with those machine-specific changes.
You can accomplish this through a recipe that is a BitBake append
(<filename>.bbappend</filename>) file.
</para>
</section>
<section id='append-bbappend-files'>
<title>Append Files</title>
<para>
Append files, which are files that have the
<filename>.bbappend</filename> file extension, extend or
override information in an existing recipe file.
</para>
<para>
BitBake expects every append file to have a corresponding recipe file.
Furthermore, the append file and corresponding recipe file
must use the same root filename.
The filenames can differ only in the file type suffix used
(e.g. <filename>formfactor_0.0.bb</filename> and
<filename>formfactor_0.0.bbappend</filename>).
</para>
<para>
Information in append files extends or
overrides the information in the underlying,
similarly-named recipe files.
</para>
<para>
When you name an append file, you can use the
"<filename>%</filename>" wildcard character to allow for matching
recipe names.
For example, suppose you have an append file named
as follows:
<literallayout class='monospaced'>
busybox_1.21.%.bbappend
</literallayout>
That append file would match any <filename>busybox_1.21.</filename><replaceable>x</replaceable><filename>.bb</filename>
version of the recipe.
So, the append file would match the following recipe names:
<literallayout class='monospaced'>
busybox_1.21.1.bb
busybox_1.21.2.bb
busybox_1.21.3.bb
</literallayout>
<note><title>Important</title>
The use of the "<filename>%</filename>" character
is limited in that it only works directly in front of the
<filename>.bbappend</filename> portion of the append file's
name.
You cannot use the wildcard character in any other
location of the name.
</note>
If the <filename>busybox</filename> recipe was updated to
<filename>busybox_1.3.0.bb</filename>, the append name would not
match.
However, if you named the append file
<filename>busybox_1.%.bbappend</filename>, then you would have a match.
</para>
<para>
In the most general case, you could name the append file something as
simple as <filename>busybox_%.bbappend</filename> to be entirely
version independent.
</para>

<title>Obtaining BitBake</title>
<para>
You can obtain BitBake several different ways:
<itemizedlist>
<listitem><para><emphasis>Cloning BitBake:</emphasis>
Using Git to clone the BitBake source code repository
is the recommended method for obtaining BitBake.
Cloning the repository makes it easy to get bug fixes
and have access to stable branches and the master
branch.
Once you have cloned BitBake, you should use
the latest stable
branch for development since the master branch is for
BitBake development and might contain less stable changes.
</para>
<para>You usually need a version of BitBake
that matches the metadata you are using.
The metadata is generally backwards compatible but
not forward compatible.</para>
<para>Here is an example that clones the BitBake repository:
<literallayout class='monospaced'>
$ git clone git://git.openembedded.org/bitbake
</literallayout>
This command clones the BitBake Git repository into a
directory called <filename>bitbake</filename>.
Alternatively, you can
designate a directory after the
<filename>git clone</filename> command
if you want to call the new directory something
other than <filename>bitbake</filename>.
Here is an example that names the directory
<filename>bbdev</filename>:
<literallayout class='monospaced'>
$ git clone git://git.openembedded.org/bitbake bbdev
</literallayout></para></listitem>
<listitem><para><emphasis>Installation using your Distribution
Package Management System:</emphasis>
This method is not
recommended because the BitBake version that is
provided by your distribution, in most cases,
is several
releases behind a snapshot of the BitBake repository.
</para></listitem>
<listitem><para><emphasis>Taking a snapshot of BitBake:</emphasis>
Downloading a snapshot of BitBake from the
source code repository gives you access to a known
branch or release of BitBake.
<note>
Cloning the Git repository, as described earlier,
is the preferred method for getting BitBake.
Cloning the repository makes it easier to update as
patches are added to the stable branches.
</note></para>
<para>The following example downloads a snapshot of
BitBake version 1.17.0:
<literallayout class='monospaced'>
$ wget http://git.openembedded.org/bitbake/snapshot/bitbake-1.17.0.tar.gz
$ tar zxpvf bitbake-1.17.0.tar.gz
</literallayout>
After extraction of the tarball using the tar utility,
you have a directory entitled
<filename>bitbake-1.17.0</filename>.
</para></listitem>
<listitem><para><emphasis>Using the BitBake that Comes With Your
Build Checkout:</emphasis>
A final possibility for getting a copy of BitBake is that it
already comes with your checkout of a larger Bitbake-based build
system, such as Poky.
Rather than manually checking out individual layers and
gluing them together yourself, you can check
out an entire build system.
The checkout will already include a version of BitBake that
has been thoroughly tested for compatibility with the other
components.
For information on how to check out a particular BitBake-based
build system, consult that build system's supporting documentation.

<title>The BitBake Command</title>
<para>
The <filename>bitbake</filename> command is the primary interface
to the BitBake tool.
This section presents the BitBake command syntax and provides
several execution examples.
</para>
<section id='usage-and-syntax'>
<title>Usage and syntax</title>
<para>
Following is the usage and syntax for BitBake:
<literallayout class='monospaced'>
$ bitbake -h
Usage: bitbake [options] [recipename/target recipe:do_task ...]
Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
will provide the layer, BBFILES and other configuration information.
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-b BUILDFILE, --buildfile=BUILDFILE
Execute tasks from a specific .bb recipe directly.
WARNING: Does not handle any dependencies from other
recipes.
-k, --continue Continue as much as possible after an error. While the
target that failed and anything depending on it cannot
be built, as much as possible will be built before
stopping.
-f, --force Force the specified targets/task to run (invalidating
any existing stamp file).
-c CMD, --cmd=CMD Specify the task to execute. The exact options
available depend on the metadata. Some examples might
be 'compile' or 'populate_sysroot' or 'listtasks' may
give a list of the tasks available.
-C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP
Invalidate the stamp for the specified task such as
'compile' and then run the default task for the
specified target(s).
-r PREFILE, --read=PREFILE
Read the specified file before bitbake.conf.
-R POSTFILE, --postread=POSTFILE
Read the specified file after bitbake.conf.
-v, --verbose Enable tracing of shell tasks (with 'set -x'). Also
print bb.note(...) messages to stdout (in addition to
writing them to ${T}/log.do_&lt;task&gt;).
-D, --debug Increase the debug level. You can specify this more
than once. -D sets the debug level to 1, where only
bb.debug(1, ...) messages are printed to stdout; -DD
sets the debug level to 2, where both bb.debug(1, ...)
and bb.debug(2, ...) messages are printed; etc.
Without -D, no debug messages are printed. Note that
-D only affects output to stdout. All debug messages
are written to ${T}/log.do_taskname, regardless of the
debug level.
-q, --quiet Output less log message data to the terminal. You can
specify this more than once.
-n, --dry-run Don't execute, just go through the motions.
-S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER
Dump out the signature construction information, with
no task execution. The SIGNATURE_HANDLER parameter is
passed to the handler. Two common values are none and
printdiff but the handler may define more/less. none
means only dump the signature, printdiff means compare
the dumped signature with the cached one.
-p, --parse-only Quit after parsing the BB recipes.
-s, --show-versions Show current and preferred versions of all recipes.
-e, --environment Show the global or per-recipe environment complete
with information about where variables were
set/changed.
-g, --graphviz Save dependency tree information for the specified
targets in the dot syntax.
-I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED
Assume these dependencies don't exist and are already
provided (equivalent to ASSUME_PROVIDED). Useful to
make dependency graphs more appealing
-l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
Show debug logging for the specified logging domains
-P, --profile Profile the command and save reports.
-u UI, --ui=UI The user interface to use (knotty, ncurses or taskexp
- default knotty).
--token=XMLRPCTOKEN Specify the connection token to be used when
connecting to a remote server.
--revisions-changed Set the exit code depending on whether upstream
floating revisions have changed or not.
--server-only Run bitbake without a UI, only starting a server
(cooker) process.
-B BIND, --bind=BIND The name/address for the bitbake xmlrpc server to bind
to.
-T SERVER_TIMEOUT, --idle-timeout=SERVER_TIMEOUT
Set timeout to unload bitbake server due to
inactivity, set to -1 means no unload, default:
Environment variable BB_SERVER_TIMEOUT.
--no-setscene Do not run any setscene tasks. sstate will be ignored
and everything needed, built.
--setscene-only Only run setscene tasks, don't run any real tasks.
--remote-server=REMOTE_SERVER
Connect to the specified server.
-m, --kill-server Terminate any running bitbake server.
--observe-only Connect to a server as an observing-only client.
--status-only Check the status of the remote bitbake server.
-w WRITEEVENTLOG, --write-log=WRITEEVENTLOG
Writes the event log of the build to a bitbake event
json file. Use '' (empty string) to assign the name
automatically.
--runall=RUNALL Run the specified task for any recipe in the taskgraph
of the specified target (even if it wouldn't otherwise
have run).
--runonly=RUNONLY Run only the specified task within the taskgraph of
the specified targets (and any task dependencies those
tasks may have).

<title>Examples</title>
<para>
This section presents some examples showing how to use BitBake.
</para>
<section id='example-executing-a-task-against-a-single-recipe'>
<title>Executing a Task Against a Single Recipe</title>
<para>
Executing tasks for a single recipe file is relatively simple.
You specify the file in question, and BitBake parses
it and executes the specified task.
If you do not specify a task, BitBake executes the default
task, which is "build”.
BitBake obeys inter-task dependencies when doing
so.
</para>
<para>
The following command runs the build task, which is
the default task, on the <filename>foo_1.0.bb</filename>
recipe file:
<literallayout class='monospaced'>
$ bitbake -b foo_1.0.bb
</literallayout>
The following command runs the clean task on the
<filename>foo.bb</filename> recipe file:
<literallayout class='monospaced'>
$ bitbake -b foo.bb -c clean
</literallayout>
<note>
The "-b" option explicitly does not handle recipe
dependencies.
Other than for debugging purposes, it is instead
recommended that you use the syntax presented in the
next section.
</note>
</para>
</section>
<section id='executing-tasks-against-a-set-of-recipe-files'>
<title>Executing Tasks Against a Set of Recipe Files</title>
<para>
There are a number of additional complexities introduced
when one wants to manage multiple <filename>.bb</filename>
files.
Clearly there needs to be a way to tell BitBake what
files are available and, of those, which you
want to execute.
There also needs to be a way for each recipe
to express its dependencies, both for build-time and
runtime.
There must be a way for you to express recipe preferences
when multiple recipes provide the same functionality, or when
there are multiple versions of a recipe.
</para>
<para>
The <filename>bitbake</filename> command, when not using
"--buildfile" or "-b" only accepts a "PROVIDES".
You cannot provide anything else.
By default, a recipe file generally "PROVIDES" its
"packagename" as shown in the following example:
<literallayout class='monospaced'>
$ bitbake foo
</literallayout>
This next example "PROVIDES" the package name and also uses
the "-c" option to tell BitBake to just execute the
<filename>do_clean</filename> task:
<literallayout class='monospaced'>
$ bitbake -c clean foo
</literallayout>
</para>
</section>
<section id='executing-a-list-of-task-and-recipe-combinations'>
<title>Executing a List of Task and Recipe Combinations</title>
<para>
The BitBake command line supports specifying different
tasks for individual targets when you specify multiple
targets.
For example, suppose you had two targets (or recipes)
<filename>myfirstrecipe</filename> and
<filename>mysecondrecipe</filename> and you needed
BitBake to run <filename>taskA</filename> for the first
recipe and <filename>taskB</filename> for the second
recipe:
<literallayout class='monospaced'>
$ bitbake myfirstrecipe:do_taskA mysecondrecipe:do_taskB
</literallayout>
</para>
</section>
<section id='generating-dependency-graphs'>
<title>Generating Dependency Graphs</title>
<para>
BitBake is able to generate dependency graphs using
the <filename>dot</filename> syntax.
You can convert these graphs into images using the
<filename>dot</filename> tool from
<ulink url='http://www.graphviz.org'>Graphviz</ulink>.
</para>
<para>
When you generate a dependency graph, BitBake writes three files
to the current working directory:
<itemizedlist>
<listitem><para>
<emphasis><filename>recipe-depends.dot</filename>:</emphasis>
Shows dependencies between recipes (i.e. a collapsed version of
<filename>task-depends.dot</filename>).
</para></listitem>
<listitem><para>
<emphasis><filename>task-depends.dot</filename>:</emphasis>
Shows dependencies between tasks.
These dependencies match BitBake's internal task execution list.
</para></listitem>
<listitem><para>
<emphasis><filename>pn-buildlist</filename>:</emphasis>
Shows a simple list of targets that are to be built.
</para></listitem>
</itemizedlist>
</para>
<para>
To stop depending on common depends, use the "-I" depend
option and BitBake omits them from the graph.
Leaving this information out can produce more readable graphs.
This way, you can remove from the graph
<filename>DEPENDS</filename> from inherited classes
such as <filename>base.bbclass</filename>.
</para>
<para>
Here are two examples that create dependency graphs.
The second example omits depends common in OpenEmbedded from
the graph:
<literallayout class='monospaced'>
$ bitbake -g foo
$ bitbake -g -I virtual/kernel -I eglibc foo
</literallayout>
</para>
</section>
<section id='executing-a-multiple-configuration-build'>
<title>Executing a Multiple Configuration Build</title>
<para>
BitBake is able to build multiple images or packages
using a single command where the different targets
require different configurations (multiple configuration
builds).
Each target, in this scenario, is referred to as a
"multiconfig".
</para>
<para>
To accomplish a multiple configuration build, you must
define each target's configuration separately using
a parallel configuration file in the build directory.
The location for these multiconfig configuration files
is specific.
They must reside in the current build directory in
a sub-directory of <filename>conf</filename> named
<filename>multiconfig</filename>.
Following is an example for two separate targets:
<imagedata fileref="figures/bb_multiconfig_files.png" align="center" width="4in" depth="3in" />
</para>
<para>
The reason for this required file hierarchy
is because the <filename>BBPATH</filename> variable
is not constructed until the layers are parsed.
Consequently, using the configuration file as a
pre-configuration file is not possible unless it is
located in the current working directory.
</para>
<para>
Minimally, each configuration file must define the
machine and the temporary directory BitBake uses
for the build.
Suggested practice dictates that you do not
overlap the temporary directories used during the
builds.
</para>
<para>
Aside from separate configuration files for each
target, you must also enable BitBake to perform multiple
configuration builds.
Enabling is accomplished by setting the
<link linkend='var-bb-BBMULTICONFIG'><filename>BBMULTICONFIG</filename></link>
variable in the <filename>local.conf</filename>
configuration file.
As an example, suppose you had configuration files
for <filename>target1</filename> and
<filename>target2</filename> defined in the build
directory.
The following statement in the
<filename>local.conf</filename> file both enables
BitBake to perform multiple configuration builds and
specifies the two multiconfigs:
<literallayout class='monospaced'>
BBMULTICONFIG = "target1 target2"
</literallayout>
</para>
<para>
Once the target configuration files are in place and
BitBake has been enabled to perform multiple configuration
builds, use the following command form to start the
builds:
<literallayout class='monospaced'>
$ bitbake [multiconfig:<replaceable>multiconfigname</replaceable>:]<replaceable>target</replaceable> [[[multiconfig:<replaceable>multiconfigname</replaceable>:]<replaceable>target</replaceable>] ... ]
</literallayout>
Here is an example for two multiconfigs:
<filename>target1</filename> and
<filename>target2</filename>:
<literallayout class='monospaced'>
$ bitbake multiconfig:target1:<replaceable>target</replaceable> multiconfig:target2:<replaceable>target</replaceable>
</literallayout>
</para>
</section>
<section id='bb-enabling-multiple-configuration-build-dependencies'>
<title>Enabling Multiple Configuration Build Dependencies</title>
<para>
Sometimes dependencies can exist between targets
(multiconfigs) in a multiple configuration build.
For example, suppose that in order to build an image
for a particular architecture, the root filesystem of
another build for a different architecture needs to
exist.
In other words, the image for the first multiconfig depends
on the root filesystem of the second multiconfig.
This dependency is essentially that the task in the recipe
that builds one multiconfig is dependent on the
completion of the task in the recipe that builds
another multiconfig.
</para>
<para>
To enable dependencies in a multiple configuration
build, you must declare the dependencies in the recipe
using the following statement form:
<literallayout class='monospaced'>
<replaceable>task_or_package</replaceable>[mcdepends] = "multiconfig:<replaceable>from_multiconfig</replaceable>:<replaceable>to_multiconfig</replaceable>:<replaceable>recipe_name</replaceable>:<replaceable>task_on_which_to_depend</replaceable>"
</literallayout>
To better show how to use this statement, consider an
example with two multiconfigs: <filename>target1</filename>
and <filename>target2</filename>:
<literallayout class='monospaced'>
<replaceable>image_task</replaceable>[mcdepends] = "multiconfig:target1:target2:<replaceable>image2</replaceable>:<replaceable>rootfs_task</replaceable>"
</literallayout>
In this example, the
<replaceable>from_multiconfig</replaceable> is "target1" and
the <replaceable>to_multiconfig</replaceable> is "target2".
The task on which the image whose recipe contains
<replaceable>image_task</replaceable> depends on the
completion of the <replaceable>rootfs_task</replaceable>
used to build out <replaceable>image2</replaceable>, which
is associated with the "target2" multiconfig.
</para>
<para>
Once you set up this dependency, you can build the
"target1" multiconfig using a BitBake command as follows:
<literallayout class='monospaced'>
$ bitbake multiconfig:target1:<replaceable>image1</replaceable>
</literallayout>
This command executes all the tasks needed to create
<replaceable>image1</replaceable> for the "target1"
multiconfig.
Because of the dependency, BitBake also executes through
the <replaceable>rootfs_task</replaceable> for the "target2"
multiconfig build.
</para>
<para>
Having a recipe depend on the root filesystem of another
build might not seem that useful.
Consider this change to the statement in the
<replaceable>image1</replaceable> recipe:
<literallayout class='monospaced'>
<replaceable>image_task</replaceable>[mcdepends] = "multiconfig:target1:target2:<replaceable>image2</replaceable>:<replaceable>image_task</replaceable>"
</literallayout>
In this case, BitBake must create
<replaceable>image2</replaceable> for the "target2"
build since the "target1" build depends on it.
</para>
<para>
Because "target1" and "target2" are enabled for multiple
configuration builds and have separate configuration
files, BitBake places the artifacts for each build in the
respective temporary build directories.

Browser wrangling and typographic design by
Oyvind Kolas / pippin@gimp.org
Customised for Poky by
Matthew Allum / mallum@o-hand.com
Thanks to:
Liam R. E. Quin
William Skaggs
Jakub Steiner
Structure
---------
The stylesheet is divided into the following sections:
Positioning
Margins, paddings, width, font-size, clearing.
Decorations
Borders, style
Colors
Colors
Graphics
Graphical backgrounds
Nasty IE tweaks
Workarounds needed to make it work in internet explorer,
currently makes the stylesheet non validating, but up until
this point it is validating.
Mozilla extensions
Transparency for footer
Rounded corners on boxes

<title>Introduction</title>
<section>
<title>Overview</title>
<para>BitBake is, at its simplest, a tool for executing
tasks and managing metadata. As such, its similarities to GNU make and other
build tools are readily apparent. It was inspired by Portage, the package management system used by the Gentoo Linux distribution. BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions, including OpenZaurus and Familiar.</para>
</section>
<section>
<title>Background and goals</title>
<para>Prior to BitBake, no other build tool adequately met
the needs of an aspiring embedded Linux distribution. All of the
buildsystems used by traditional desktop Linux distributions lacked
important functionality, and none of the ad-hoc
<emphasis>buildroot</emphasis> systems, prevalent in the
embedded space, were scalable or maintainable.</para>
<para>Some important goals for BitBake were:
<itemizedlist>
<listitem><para>Handle crosscompilation.</para></listitem>
<listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
<listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
<listitem><para>Must be Linux distribution agnostic (both build and target).</para></listitem>
<listitem><para>Must be architecture agnostic</para></listitem>
<listitem><para>Must support multiple build and target operating systems (including Cygwin, the BSDs, etc).</para></listitem>
<listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
<listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
<listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
<listitem><para>Must make it easy to collaborate
between multiple projects using BitBake for their
builds.</para></listitem>
<listitem><para>Should provide an inheritance mechanism to
share common metadata between many packages.</para></listitem>
<listitem><para>Et cetera...</para></listitem>
</itemizedlist>
</para>
<para>BitBake satisfies all these and many more. Flexibility and power have always been the priorities. It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>

<chapter>
<title>Metadata</title>
<section>
<title>Description</title>
<itemizedlist>
<para>BitBake metadata can be classified into 3 major areas:</para>
<listitem>
<para>Configuration Files</para>
</listitem>
<listitem>
<para>.bb Files</para>
</listitem>
<listitem>
<para>Classes</para>
</listitem>
</itemizedlist>
<para>What follows are a large number of examples of BitBake metadata. Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
<section>
<title>Basic variable setting</title>
<para><screen><varname>VARIABLE</varname> = "value"</screen></para>
<para>In this example, <varname>VARIABLE</varname> is <literal>value</literal>.</para>
</section>
<section>
<title>Variable expansion</title>
<para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>
<para><screen><varname>A</varname> = "aval"
<varname>B</varname> = "pre${A}post"</screen></para>
<para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
</section>
<section>
<title>Setting a default value (?=)</title>
<para><screen><varname>A</varname> ?= "aval"</screen></para>
<para>If <varname>A</varname> is set before the above is called, it will retain its previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>. Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
</section>
<section>
<title>Setting a default value (??=)</title>
<para><screen><varname>A</varname> ??= "somevalue"</screen></para>
<para><screen><varname>A</varname> ??= "someothervalue"</screen></para>
<para>If <varname>A</varname> is set before the above, it will retain that value. If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>. This is a lazy version of ??=, in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used.</para>
</section>
<section>
<title>Immediate variable expansion (:=)</title>
<para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>
<para><screen><varname>T</varname> = "123"
<varname>A</varname> := "${B} ${A} test ${T}"
<varname>T</varname> = "456"
<varname>B</varname> = "${T} bval"
<varname>C</varname> = "cval"
<varname>C</varname> := "${C}append"</screen></para>
<para>In that example, <varname>A</varname> would contain <literal> test 123</literal>, <varname>B</varname> would contain <literal>456 bval</literal>, and <varname>C</varname> would be <literal>cvalappend</literal>.</para>
</section>
<section>
<title>Appending (+=) and prepending (=+)</title>
<para><screen><varname>B</varname> = "bval"
<varname>B</varname> += "additionaldata"
<varname>C</varname> = "cval"
<varname>C</varname> =+ "test"</screen></para>
<para>In this example, <varname>B</varname> is now <literal>bval additionaldata</literal> and <varname>C</varname> is <literal>test cval</literal>.</para>
</section>
<section>
<title>Appending (.=) and prepending (=.) without spaces</title>
<para><screen><varname>B</varname> = "bval"
<varname>B</varname> .= "additionaldata"
<varname>C</varname> = "cval"
<varname>C</varname> =. "test"</screen></para>
<para>In this example, <varname>B</varname> is now <literal>bvaladditionaldata</literal> and <varname>C</varname> is <literal>testcval</literal>. In contrast to the above appending and prepending operators, no additional space
will be introduced.</para>
</section>
<section>
<title>Conditional metadata set</title>
<para>OVERRIDES is a <quote>:</quote> separated variable containing each item you want to satisfy conditions. So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version. Example:</para>
<para><screen><varname>OVERRIDES</varname> = "architecture:os:machine"
<varname>TEST</varname> = "defaultvalue"
<varname>TEST_os</varname> = "osspecificvalue"
<varname>TEST_condnotinoverrides</varname> = "othercondvalue"</screen></para>
<para>In this example, <varname>TEST</varname> would be <literal>osspecificvalue</literal>, due to the condition <quote>os</quote> being in <varname>OVERRIDES</varname>.</para>
</section>
<section>
<title>Conditional appending</title>
<para>BitBake also supports appending and prepending to variables based on whether something is in OVERRIDES. Example:</para>
<para><screen><varname>DEPENDS</varname> = "glibc ncurses"
<varname>OVERRIDES</varname> = "machine:local"
<varname>DEPENDS_append_machine</varname> = " libmad"</screen></para>
<para>In this example, <varname>DEPENDS</varname> is set to <literal>glibc ncurses libmad</literal>.</para>
</section>
<section>
<title>Inclusion</title>
<para>Next, there is the <literal>include</literal> directive, which causes BitBake to parse whatever file you specify, and insert it at that location, which is not unlike <command>make</command>. However, if the path specified on the <literal>include</literal> line is a relative path, BitBake will locate the first one it can find within <envar>BBPATH</envar>.</para>
</section>
<section>
<title>Requiring inclusion</title>
<para>In contrast to the <literal>include</literal> directive, <literal>require</literal> will
raise an ParseError if the file to be included cannot be found. Otherwise it will behave just like the <literal>
include</literal> directive.</para>
</section>
<section>
<title>Python variable expansion</title>
<para><screen><varname>DATE</varname> = "${@time.strftime('%Y%m%d',time.gmtime())}"</screen></para>
<para>This would result in the <varname>DATE</varname> variable containing today's date.</para>
</section>
<section>
<title>Defining executable metadata</title>
<para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
<para><screen>do_mytask () {
echo "Hello, world!"
}</screen></para>
<para>This is essentially identical to setting a variable, except that this variable happens to be executable shell code.</para>
<para><screen>python do_printdate () {
import time
print time.strftime('%Y%m%d', time.gmtime())
}</screen></para>
<para>This is the similar to the previous, but flags it as Python so that BitBake knows it is Python code.</para>
</section>
<section>
<title>Defining Python functions into the global Python namespace</title>
<para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
<para><screen>def get_depends(bb, d):
if bb.data.getVar('SOMECONDITION', d, True):
return "dependencywithcond"
else:
return "dependency"
<varname>SOMECONDITION</varname> = "1"
<varname>DEPENDS</varname> = "${@get_depends(bb, d)}"</screen></para>
<para>This would result in <varname>DEPENDS</varname> containing <literal>dependencywithcond</literal>.</para>
</section>
<section>
<title>Variable flags</title>
<para>Variables can have associated flags which provide a way of tagging extra information onto a variable. Several flags are used internally by BitBake but they can be used externally too if needed. The standard operations mentioned above also work on flags.</para>
<para><screen><varname>VARIABLE</varname>[<varname>SOMEFLAG</varname>] = "value"</screen></para>
<para>In this example, <varname>VARIABLE</varname> has a flag, <varname>SOMEFLAG</varname> which is set to <literal>value</literal>.</para>
</section>
<section>
<title>Inheritance</title>
<para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
<para>The <literal>inherit</literal> directive is a means of specifying what classes of functionality your .bb requires. It is a rudimentary form of inheritance. For example, you can easily abstract out the tasks involved in building a package that uses autoconf and automake, and put that into a bbclass for your packages to make use of. A given bbclass is located by searching for classes/filename.oeclass in <envar>BBPATH</envar>, where filename is what you inherited.</para>
</section>
<section>
<title>Tasks</title>
<para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
<para>In BitBake, each step that needs to be run for a given .bb is known as a task. There is a command <literal>addtask</literal> to add new tasks (must be a defined Python executable metadata and must start with <quote>do_</quote>) and describe intertask dependencies.</para>
<para><screen>python do_printdate () {
import time
print time.strftime('%Y%m%d', time.gmtime())
}
addtask printdate before do_build</screen></para>
<para>This defines the necessary Python function and adds it as a task which is now a dependency of do_build, the default task. If anyone executes the do_build task, that will result in do_printdate being run first.</para>
</section>
<section>
<title>Events</title>
<para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
<para>BitBake allows installation of event handlers. Events are triggered at certain points during operation, such as the beginning of operation against a given .bb, the start of a given task, task failure, task success, et cetera. The intent is to make it easy to do things like email notification on build failure.</para>
<para><screen>addhandler myclass_eventhandler
python myclass_eventhandler() {
from bb.event import getName
from bb import data
print("The name of the Event is %s" % getName(e))
print("The file we run for is %s" % data.getVar('FILE', e.data, True))
}
</screen></para><para>
This event handler gets called every time an event is triggered. A global variable <varname>e</varname> is defined. <varname>e</varname>.data contains an instance of bb.data. With the getName(<varname>e</varname>)
method one can get the name of the triggered event.</para><para>The above event handler prints the name
of the event and the content of the <varname>FILE</varname> variable.</para>
</section>
<section>
<title>Variants</title>
<para>Two BitBake features exist to facilitate the creation of multiple buildable incarnations from a single recipe file.</para>
<para>The first is <varname>BBCLASSEXTEND</varname>. This variable is a space separated list of classes used to "extend" the recipe for each variant. As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available. This second incarantion will have the "native" class inherited.</para>
<para>The second feature is <varname>BBVERSIONS</varname>. This variable allows a single recipe to build multiple versions of a project from a single recipe file, and allows you to specify conditional metadata (using the <varname>OVERRIDES</varname> mechanism) for a single version, or an optionally named range of versions:</para>
<para><screen>BBVERSIONS = "1.0 2.0 git"
SRC_URI_git = "git://someurl/somepath.git"</screen></para>
<para><screen>BBVERSIONS = "1.0.[0-6]:1.0.0+ \
1.0.[7-9]:1.0.7+"
SRC_URI_append_1.0.7+ = "file://some_patch_which_the_new_versions_need.patch;patch=1"</screen></para>
<para>Note that the name of the range will default to the original version of the recipe, so given OE, a recipe file of foo_1.0.0+.bb will default the name of its versions to 1.0.0+. This is useful, as the range name is not only placed into overrides; it's also made available for the metadata to use in the form of the <varname>BPV</varname> variable, for use in file:// search paths (<varname>FILESPATH</varname>).</para>
</section>
</section>
<section>
<title>Dependency handling</title>
<para>BitBake 1.7.x onwards works with the metadata at the task level since this is optimal when dealing with multiple threads of execution. A robust method of specifing task dependencies is therefore needed. </para>
<section>
<title>Dependencies internal to the .bb file</title>
<para>Where the dependencies are internal to a given .bb file, the dependencies are handled by the previously detailed addtask directive.</para>
</section>
<section>
<title>DEPENDS</title>
<para>DEPENDS lists build time dependencies. The 'deptask' flag for tasks is used to signify the task of each item listed in DEPENDS which must have completed before that task can be executed.</para>
<para><screen>do_configure[deptask] = "do_populate_staging"</screen></para>
<para>means the do_populate_staging task of each item in DEPENDS must have completed before do_configure can execute.</para>
</section>
<section>
<title>RDEPENDS</title>
<para>RDEPENDS lists runtime dependencies. The 'rdeptask' flag for tasks is used to signify the task of each item listed in RDEPENDS which must have completed before that task can be executed.</para>
<para><screen>do_package_write[rdeptask] = "do_package"</screen></para>
<para>means the do_package task of each item in RDEPENDS must have completed before do_package_write can execute.</para>
</section>
<section>
<title>Recursive DEPENDS</title>
<para>These are specified with the 'recdeptask' flag and is used signify the task(s) of each DEPENDS which must have completed before that task can be executed. It applies recursively so the DEPENDS of each item in the original DEPENDS must be met and so on.</para>
</section>
<section>
<title>Recursive RDEPENDS</title>
<para>These are specified with the 'recrdeptask' flag and is used signify the task(s) of each RDEPENDS which must have completed before that task can be executed. It applies recursively so the RDEPENDS of each item in the original RDEPENDS must be met and so on. It also runs all DEPENDS first.</para>
</section>
<section>
<title>Inter task</title>
<para>The 'depends' flag for tasks is a more generic form of which allows an interdependency on specific tasks rather than specifying the data in DEPENDS or RDEPENDS.</para>
<para><screen>do_patch[depends] = "quilt-native:do_populate_staging"</screen></para>
<para>means the do_populate_staging task of the target quilt-native must have completed before the do_patch can execute.</para>
</section>
</section>
<section>
<title>Parsing</title>
<section>
<title>Configuration files</title>
<para>The first kind of metadata in BitBake is configuration metadata. This metadata is global, and therefore affects <emphasis>all</emphasis> packages and tasks which are executed.</para>
<para>BitBake will first search the current working directory for an optional "conf/bblayers.conf" configuration file. This file is expected to contain a BBLAYERS variable which is a space delimited list of 'layer' directories. For each directory in this list, a "conf/layer.conf" file will be searched for and parsed with the LAYERDIR variable being set to the directory where the layer was found. The idea is these files will setup BBPATH and other variables correctly for a given build directory automatically for the user.</para>
<para>BitBake will then expect to find 'conf/bitbake.conf' somewhere in the user specified <envar>BBPATH</envar>. That configuration file generally has include directives to pull in any other metadata (generally files specific to architecture, machine, <emphasis>local</emphasis> and so on).</para>
<para>Only variable definitions and include directives are allowed in .conf files.</para>
</section>
<section>
<title>Classes</title>
<para>BitBake classes are our rudimentary inheritance mechanism. As briefly mentioned in the metadata introduction, they're parsed when an <literal>inherit</literal> directive is encountered, and they are located in classes/ relative to the directories in <envar>BBPATH</envar>.</para>
</section>
<section>
<title>.bb files</title>
<para>A BitBake (.bb) file is a logical unit of tasks to be executed. Normally this is a package to be built. Inter-.bb dependencies are obeyed. The files themselves are located via the <varname>BBFILES</varname> variable, which is set to a space separated list of .bb files, and does handle wildcards.</para>
</section>
</section>

<chapter>
<title>File download support</title>
<section>
<title>Overview</title>
<para>BitBake provides support to download files this procedure is called fetching. The SRC_URI is normally used to tell BitBake which files to fetch. The next sections will describe the available fetchers and their options. Each fetcher honors a set of variables and per URI parameters separated by a <quote>;</quote> consisting of a key and a value. The semantics of the variables and parameters are defined by the fetcher. BitBake tries to have consistent semantics between the different fetchers.
</para>
</section>
<section>
<title>Local file fetcher</title>
<para>The URN for the local file fetcher is <emphasis>file</emphasis>. The filename can be either absolute or relative. If the filename is relative, <varname>FILESPATH</varname> and <varname>FILESDIR</varname> will be used to find the appropriate relative file, depending on the <varname>OVERRIDES</varname>. Single files and complete directories can be specified.
<screen><varname>SRC_URI</varname>= "file://relativefile.patch"
<varname>SRC_URI</varname>= "file://relativefile.patch;this=ignored"
<varname>SRC_URI</varname>= "file:///Users/ich/very_important_software"
</screen>
</para>
</section>
<section>
<title>CVS file fetcher</title>
<para>The URN for the CVS fetcher is <emphasis>cvs</emphasis>. This fetcher honors the variables <varname>DL_DIR</varname>, <varname>SRCDATE</varname>, <varname>FETCHCOMMAND_cvs</varname>, <varname>UPDATECOMMAND_cvs</varname>. <varname>DL_DIR</varname> specifies where a temporary checkout is saved. <varname>SRCDATE</varname> specifies which date to use when doing the fetching (the special value of "now" will cause the checkout to be updated on every build). <varname>FETCHCOMMAND</varname> and <varname>UPDATECOMMAND</varname> specify which executables to use for the CVS checkout or update.
</para>
<para>The supported parameters are <varname>module</varname>, <varname>tag</varname>, <varname>date</varname>, <varname>method</varname>, <varname>localdir</varname>, <varname>rsh</varname> and <varname>scmdata</varname>. The <varname>module</varname> specifies which module to check out, the <varname>tag</varname> describes which CVS TAG should be used for the checkout. By default the TAG is empty. A <varname>date</varname> can be specified to override the SRCDATE of the configuration to checkout a specific date. The special value of "now" will cause the checkout to be updated on every build.<varname>method</varname> is by default <emphasis>pserver</emphasis>. If <emphasis>ext</emphasis> is used the <varname>rsh</varname> parameter will be evaluated and <varname>CVS_RSH</varname> will be set. Finally, <varname>localdir</varname> is used to checkout into a special directory relative to <varname>CVSDIR</varname>.
<screen><varname>SRC_URI</varname> = "cvs://CVSROOT;module=mymodule;tag=some-version;method=ext"
<varname>SRC_URI</varname> = "cvs://CVSROOT;module=mymodule;date=20060126;localdir=usethat"

</section>
<section>
<title>HTTP/FTP fetcher</title>
<para>The URNs for the HTTP/FTP fetcher are <emphasis>http</emphasis>, <emphasis>https</emphasis> and <emphasis>ftp</emphasis>. This fetcher honors the variables <varname>DL_DIR</varname>, <varname>FETCHCOMMAND_wget</varname>, <varname>PREMIRRORS</varname>, <varname>MIRRORS</varname>. The <varname>DL_DIR</varname> defines where to store the fetched file. <varname>FETCHCOMMAND</varname> contains the command used for fetching. <quote>${URI}</quote> and <quote>${FILES}</quote> will be replaced by the URI and basename of the file to be fetched. <varname>PREMIRRORS</varname> will be tried first when fetching a file. If that fails, the actual file will be tried and finally all <varname>MIRRORS</varname> will be tried.
</para>
<para>The only supported parameter is <varname>md5sum</varname>. After a fetch the <varname>md5sum</varname> of the file will be calculated and the two sums will be compared.
</para>
<para><screen><varname>SRC_URI</varname> = "http://oe.handhelds.org/not_there.aac;md5sum=12343"
<varname>SRC_URI</varname> = "ftp://oe.handhelds.org/not_there_as_well.aac;md5sum=1234"

<para>This fetcher honors the variables <varname>FETCHCOMMAND_svn</varname>, <varname>DL_DIR</varname>, <varname>SRCDATE</varname>. <varname>FETCHCOMMAND</varname> contains the subversion command. <varname>DL_DIR</varname> is the directory where tarballs will be saved. <varname>SRCDATE</varname> specifies which date to use when doing the fetching (the special value of "now" will cause the checkout to be updated on every build).
</para>
<para>The supported parameters are <varname>proto</varname>, <varname>rev</varname> and <varname>scmdata</varname>. <varname>proto</varname> is the Subversion protocol, <varname>rev</varname> is the Subversion revision. If <varname>scmdata</varname> is set to <quote>keep</quote>, the <quote>.svn</quote> directories will be available during compile-time.

<title>The BitBake command</title>
<section>
<title>Introduction</title>
<para>bitbake is the primary command in the system. It facilitates executing tasks in a single .bb file, or executing a given task on a set of multiple .bb files, accounting for interdependencies amongst them.</para>
</section>
<section>
<title>Usage and syntax</title>
<para>
<screen><prompt>$ </prompt>bitbake --help
usage: bitbake [options] [package ...]
Executes the specified task (default is 'build') for a given set of BitBake files.
It expects that BBFILES is defined, which is a space separated list of files to
be executed. BBFILES does support wildcards.
Default BBFILES are the .bb files in the current directory.
options:
--version show program's version number and exit
-h, --help show this help message and exit
-b BUILDFILE, --buildfile=BUILDFILE
execute the task against this .bb file, rather than a
package from BBFILES.
-k, --continue continue as much as possible after an error. While the
target that failed, and those that depend on it,
cannot be remade, the other dependencies of these
targets can be processed all the same.
-f, --force force run of specified cmd, regardless of stamp status
-i, --interactive drop into the interactive mode also called the BitBake
shell.
-c CMD, --cmd=CMD Specify task to execute. Note that this only executes
the specified task for the providee and the packages
it depends on, i.e. 'compile' does not implicitly call
stage for the dependencies (IOW: use only if you know
what you are doing). Depending on the base.bbclass a
listtasks task is defined and will show available
tasks
-r FILE, --read=FILE read the specified file before bitbake.conf
-v, --verbose output more chit-chat to the terminal
-D, --debug Increase the debug level. You can specify this more
than once.
-n, --dry-run don't execute, just go through the motions
-p, --parse-only quit after parsing the BB files (developers only)
-s, --show-versions show current and preferred versions of all packages
-e, --environment show the global or per-package environment (this is
what used to be bbread)
-g, --graphviz emit the dependency trees of the specified packages in
the dot syntax
-I IGNORED_DOT_DEPS, --ignore-deps=IGNORED_DOT_DEPS
Stop processing at the given list of dependencies when
generating dependency graphs. This can help to make
the graph more appealing
-l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
Show debug logging for the specified logging domains
-P, --profile profile the command and print a report
</screen>
</para>
<para>
<example>
<title>Executing a task against a single .bb</title>
<para>Executing tasks for a single file is relatively simple. You specify the file in question, and BitBake parses it and executes the specified task (or <quote>build</quote> by default). It obeys intertask dependencies when doing so.</para>
<para><quote>clean</quote> task:</para>
<para><screen><prompt>$ </prompt>bitbake -b blah_1.0.bb -c clean</screen></para>
<para><quote>build</quote> task:</para>
<para><screen><prompt>$ </prompt>bitbake -b blah_1.0.bb</screen></para>
</example>
</para>
<para>
<example>
<title>Executing tasks against a set of .bb files</title>
<para>There are a number of additional complexities introduced when one wants to manage multiple .bb files. Clearly there needs to be a way to tell BitBake what files are available, and of those, which we want to execute at this time. There also needs to be a way for each .bb to express its dependencies, both for build time and runtime. There must be a way for the user to express their preferences when multiple .bb's provide the same functionality, or when there are multiple versions of a .bb.</para>
<para>The next section, Metadata, outlines how to specify such things.</para>
<para>Note that the bitbake command, when not using --buildfile, accepts a <varname>PROVIDER</varname>, not a filename or anything else. By default, a .bb generally PROVIDES its packagename, packagename-version, and packagename-version-revision.</para>
<screen><prompt>$ </prompt>bitbake blah</screen>
<screen><prompt>$ </prompt>bitbake blah-1.0</screen>
<screen><prompt>$ </prompt>bitbake blah-1.0-r0</screen>
<screen><prompt>$ </prompt>bitbake -c clean blah</screen>
<screen><prompt>$ </prompt>bitbake virtual/whatever</screen>
<screen><prompt>$ </prompt>bitbake -c clean virtual/whatever</screen>
</example>
<example>
<title>Generating dependency graphs</title>
<para>BitBake is able to generate dependency graphs using the dot syntax. These graphs can be converted
to images using the <application>dot</application> application from <ulink url="http://www.graphviz.org">Graphviz</ulink>.
Two files will be written into the current working directory, <emphasis>depends.dot</emphasis> containing dependency information at the package level and <emphasis>task-depends.dot</emphasis> containing a breakdown of the dependencies at the task level. To stop depending on common depends, one can use the <prompt>-I depend</prompt> to omit these from the graph. This can lead to more readable graphs. This way, <varname>DEPENDS</varname> from inherited classes such as base.bbclass can be removed from the graph.</para>
<screen><prompt>$ </prompt>bitbake -g blah</screen>
<screen><prompt>$ </prompt>bitbake -g -I virtual/whatever -I bloom blah</screen>
</example>
</para>
</section>
<section>
<title>Special variables</title>
<para>Certain variables affect BitBake operation:</para>
<section>
<title><varname>BB_NUMBER_THREADS</varname></title>
<para> The number of threads BitBake should run at once (default: 1).</para>
</section>
</section>
<section>
<title>Metadata</title>
<para>As you may have seen in the usage information, or in the information about .bb files, the <varname>BBFILES</varname> variable is how the BitBake tool locates its files. This variable is a space separated list of files that are available, and supports wildcards.
<example>
<title>Setting BBFILES</title>
<programlisting><varname>BBFILES</varname> = "/path/to/bbfiles/*.bb"</programlisting>
</example></para>
<para>With regard to dependencies, it expects the .bb to define a <varname>DEPENDS</varname> variable, which contains a space separated list of <quote>package names</quote>, which themselves are the <varname>PN</varname> variable. The <varname>PN</varname> variable is, in general, set to a component of the .bb filename by default.</para>
<example>
<title>Depending on another .bb</title>
<para>a.bb:
<screen>PN = "package-a"
DEPENDS += "package-b"</screen>
</para>
<para>b.bb:
<screen>PN = "package-b"</screen>
</para>
</example>
<example>
<title>Using PROVIDES</title>
<para>This example shows the usage of the <varname>PROVIDES</varname> variable, which allows a given .bb to specify what functionality it provides.</para>
<para>package1.bb:
<screen>PROVIDES += "virtual/package"</screen>
</para>
<para>package2.bb:
<screen>DEPENDS += "virtual/package"</screen>
</para>
<para>package3.bb:
<screen>PROVIDES += "virtual/package"</screen>
</para>
<para>As you can see, we have two different .bb's that provide the same functionality (virtual/package). Clearly, there needs to be a way for the person running BitBake to control which of those providers gets used. There is, indeed, such a way.</para>
<para>The following would go into a .conf file, to select package1:
<screen>PREFERRED_PROVIDER_virtual/package = "package1"</screen>
</para>
</example>
<example>
<title>Specifying version preference</title>
<para>When there are multiple <quote>versions</quote> of a given package, BitBake defaults to selecting the most recent version, unless otherwise specified. If the .bb in question has a <varname>DEFAULT_PREFERENCE</varname> set lower than the other .bb's (default is 0), then it will not be selected. This allows the person or persons maintaining the repository of .bb files to specify their preference for the default selected version. In addition, the user can specify their preferred version.</para>
<para>If the first .bb is named <filename>a_1.1.bb</filename>, then the <varname>PN</varname> variable will be set to <quote>a</quote>, and the <varname>PV</varname> variable will be set to 1.1.</para>
<para>If we then have an <filename>a_1.2.bb</filename>, BitBake will choose 1.2 by default. However, if we define the following variable in a .conf that BitBake parses, we can change that.
<screen>PREFERRED_VERSION_a = "1.1"</screen>
</para>
</example>
<example>
<title>Using <quote>bbfile collections</quote></title>
<para>bbfile collections exist to allow the user to have multiple repositories of bbfiles that contain the same exact package. For example, one could easily use them to make one's own local copy of an upstream repository, but with custom modifications that one does not want upstream. Usage:</para>
<screen>BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
BBFILE_COLLECTIONS = "upstream local"
BBFILE_PATTERN_upstream = "^/stuff/openembedded/"
BBFILE_PATTERN_local = "^/stuff/openembedded.modified/"
BBFILE_PRIORITY_upstream = "5"
BBFILE_PRIORITY_local = "10"</screen>

BitBake code parser
Parses actual code (i.e. python and shell) for functions and in-line
expressions. Used mainly to determine dependencies on other functions
and variables within the BitBake metadata. Also provides a cache for
this information in order to speed up processing.
(Not to be confused with the code that parses the metadata itself,
see lib/bb/parse/ for that).
NOTE: if you change how the parsers gather information you will almost
certainly need to increment CodeParserCache.CACHE_VERSION below so that
any existing codeparser cache gets invalidated. Additionally you'll need
to increment __cache_version__ in cache.py in order to ensure that old
recipe caches don't trigger "Taskhash mismatch" errors.

# Basically pickle, in python 2.7.3 at least, does badly with data duplication
# upon pickling and unpickling. Combine this with duplicate objects and things
# are a mess.
#
# When the sets are originally created, python calls intern() on the set keys
# which significantly improves memory usage. Sadly the pickle/unpickle process
# doesn't call intern() on the keys and results in the same strings being duplicated
# in memory. This also means pickle will save the same string multiple times in
# the cache file.
#
# By having shell and python cacheline objects with setstate/getstate, we force
# the object creation through our own routine where we can call intern (via internSet).
#
# We also use hashable frozensets and ensure we use references to these so that
# duplicates can be removed, both in memory and in the resulting pickled data.
#
# By playing these games, the size of the cache file shrinks dramatically
# meaning faster load times and the reloaded cache files also consume much less
# memory. Smaller cache files, faster load times and lower memory usage is good.
#
# A custom getstate/setstate using tuples is actually worth 15% cachesize by
# avoiding duplication of the attribute names!

to allow a function to be daemonized and return for bitbake use by Richard Purdie
Configurable daemon behaviors:
1.) The current working directory set to the "/" directory.
2.) The current file creation mode mask set to 0.
3.) Close all open files (1024).
4.) Redirect standard I/O streams to "/dev/null".
A failed call to fork() now raises an exception.

# It's often suggested that the SIGHUP signal should be ignored before
# the second fork to avoid premature termination of the process. The
# reason is that when the first child terminates, all processes, e.g.
# the second child, in the orphaned group will be sent a SIGHUP.
#
# "However, as part of the session management system, there are exactly
# two cases where SIGHUP is sent on the death of a process:
#
# 1) When the process that dies is the session leader of a session that
# is attached to a terminal device, SIGHUP is sent to all processes
# in the foreground process group of that terminal device.
# 2) When the death of a process causes a process group to become
# orphaned, and one or more processes in the orphaned group are
# stopped, then SIGHUP and SIGCONT are sent to all members of the
# orphaned group." [2]
#
# The first case can be ignored since the child is guaranteed not to have
# a controlling terminal. The second case isn't so easy to dismiss.
# The process group is orphaned when the first child terminates and
# POSIX.1 requires that every STOPPED process in an orphaned process
# group be sent a SIGHUP signal followed by a SIGCONT signal. Since the

'''
BitBake 'Fetch' implementations
This implementation is for Secure Shell (SSH), and attempts to comply with the
IETF secsh internet draft:
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
Currently does not support the sftp parameters, as this uses scp
Also does not support the 'fingerprint' connection parameter.
