1924f52cc8 documentation/adt-manual/adt-eclipse.xml: Added missing section for plug-in
Discovered a missing section for installation of the Eclipse Yocto Plug-in.
This information is critical to the release.  Jessica discovered the problem.
New section added that describes how to install the plug-in as a standard
"New Software" installation from within the Eclipse IDE.

eae4945a9d documentation: Cleaned out bad links and replaced with good
The re-structuring of the web server that holds the documents created
some bad links.  I thought I had gotten them all but apparently not.
this is a drawback of not being able to test things until after stuff
is done.  In any case, I grepped through everything and this takes
care of it.

5ec43fdbb8 documentation/dev-manual: Fixed five broken links and removed note
The restructuring of the web site where we store manuals broke some
links that were cut-and-pasted in from older work.  These slipped by
me so not changing them would direct the user to a 1.0 version of
the externally referenced manual rather than the 1.1 version.

I also got rid of a visible "WRITER'S NOTE" in the document that
was left behind.

720446629b documentation/yocto-project-qs/yocto-project-qs.xml: release name and misc.
I somehow had either dreamed the word "einstein" into the release
for 1.1 and had it in there as part of the tarball name, etc.
I have replaced this obviously with "edison."

Other edits involved making the references to outside documents
more consistent.

baf536c62c documentation/adt-manual: changes for Jessica's review.
I made several changes based on feedback from Jessica Zhang.

1. Removed "SDKVERSION" as a way of identifying the directory in
   which a toolchain tarball is installed.  I replaced with "1.1"

2. Cleaned up the bitbake command verbage to consistently use
   'bitbake' command.

3. Cleaned up an erroneous reference to the toolchain environment
   setup scripts.  I was referring the user to the oe-init-build-env
   area.

4. Changed wording to indicate that the toolchain tarball is generated
   after running bitbake rather than installing the toolchain.

5. Replaced the gmae tarball file used in an example to be the
   regular taball.

validated to be sure that the SRC_URI point to the right stuff and
that the BSP build branch exists.

resources for these changes.  These changes are the first draft.

b47f39dbc3 documentation/poky-ref-manual/faq.xml: Removed wording that focues on GNOME
Per Paul Eggleton he suggested that the wording we had about YP focusing
on the GNOME Mobile environment was misleading now.  It was in there in the
original version of the FAQ but with time has become outdated.  I simply
removed the "GNOME" part and left the part that mentions about YP
being a stable
environment and well-suited for the embedded mobile environment.

This is the second pass for re-documenting RDEPENDS, RRECOMMENDS,
MACHINE_ESSENTIALS_EXTRA_RDEPENDS, MACHINE_ESSENTIALS_EXTRA_RRECOMMENDS,
MACHINE_EXTRA_RDEPENDS, and MACHINE_EXTRA_RRECOMMENDS.  These
variables are in dire need of better explanations and examples.

fbec475275 Remove help2man dependency
The help2man script is pretty useless to us. It requires to run the target
binary to extract help information which is not possible for any of our
cross compiled target binaries.

We're not interested in man pages for -cross/-native tools.

It therefore makes no sense to have this as a core build dependency.

This patch removes the dependeny and replaces it with a script
returning false. This will trigger autotool's missing utility
to use the copy of the man page included with the sources which
is what would already happen when we tried to run cross compiled
binaries anyway.

currently we have allarch type of recipes, which may still have

Also remove the PV postfix in python-pygobject DEPENDS, since multilib

means in the native case it fails on systems such as Ubuntu 11.10 where the
location of time.h has changed. Further it means the target build has had a
host-intrusion issue.

This patch disables the check for time.h, future releases of ghostscript
use standard autotools checks for time.h's location.

66934fc311 qemu-config: use pkg_postinst to generate the proper shutdown.desktop
[YOCTO #1507]

We need to remove the file qemuarm/shutdown.desktop, or else, on qemuarm,
due to the PACKAGE_ARCH overriding from all to qemuarm in base.bbclass,
the generated deb file will be stored at
tmp/deploy/deb/qemuarm/qemu-config_1.0-r21_allarch.deb rather than
tmp/deploy/deb/all/qemu-config_1.0-r21_all.deb, and the package qemu-config
won't be installable -- task-base finally rdepends on qemu-config, so we get
the do_rootfs failure:

The following packages have unmet dependencies:
|   task-base-extended: Depends: task-base but it is not going to be installed
| E: Broken packages

There is also a generic shutdown.desktop, we can keep it and use a proper
pkg_postinst to cope with the case of qemuarm.

Before learning how to prepare your system for the ADT, you need to understand
two important terms used throughout this manual:
<itemizedlist>
<listitem><para><emphasis>The Yocto Project Files:</emphasis>
This term refers to the directory structure created as a result of downloading
and unpacking a Yocto Project release tarball or setting up a Git repository
by cloning <filename>git://git.yoctoproject.org/poky</filename>.</para>
<para>The Yocto Project files contain BitBake, Documentation, metadata and
other files that all support the development environment.
Consequently, you must have the Yocto Project files in place on your development
system in order to do any development using the Yocto Project.</para>
<para>The name of the top-level directory of the Yocto Project file structure
is derived from the Yocto Project release tarball.
For example, downloading and unpacking <filename>poky-edison-6.0.tar.bz2</filename>
results in a Yocto Project source tree whose Yocto Project source directory is named
<filename>poky-edison-6.0</filename>.
If you create a Git repository, then you can name the repository anything you like.</para>

<listitem><para><emphasis>Yocto Project Build Tree:</emphasis>

The area is created when you <filename>source</filename> the Yocto Project setup
environment script that is found in the Yocto Project files area.
(e.g. <filename>oe-init-build-env</filename>).
You can create the Yocto Project build tree anywhere you want on your
development system.
Here is an example that creates the tree in <filename>mybuilds</filename>

<literallayout class='monospaced'>
$ source poky-edison-6.0/oe-init-build-env $HOME/mybuilds/YP-6.0
</literallayout>
If you don't specifically name the build directory, then BitBake creates it
in the current directory and uses the name <filename>build</filename>.
Also, if you supply an existing directory, then BitBake uses that
directory as the Yocto Project build directory and populates the build tree
beneath it.</para></listitem>

You must extract the root filesystem if you want to boot the image using NFS
or you want to use the root filesystem as the target sysroot.
For example, the Eclipse IDE environment with the Eclipse Yocto Plug-in installed allows you

Another example is if you want to develop your target application using the

<para>
To extract the root filesystem, first <filename>source</filename>
the cross-development environment setup script and then
use the <filename>runqemu-extract-sdk</filename> command on the

For example, the following commands set up the environment and then extract
the root filesystem from a previously built filesystem image tarball named
<filename>core-image-sato-sdk-qemux86-2011091411831.rootfs.tar.bz2</filename>.
The example extracts the root filesystem into the <filename>$HOME/qemux86-sato</filename>
directory:
<literallayout class='monospaced'>
$ source $HOME/poky/build/tmp/environment-setup-i586-poky-linux

<title>The Yocto Project Development Manual</title>
<section id='intro'>
<title>Introduction</title>
<para>
WRITER NOTE: The goal of this manual is to provide an over-arching development guide for using the Yocto Project.
The intent is to give the reader the “big picture” around development.
Much of the information in the manual will be detailed in other manuals.
For example, detailed information on Git, repositories and open-source in general can be found in many places.
Another example is getting set up to use the Yocto Project, which our Yocto Project Quick Start covers.
However, this manual needs to at least address it.
One might ask “What becomes of the Poky Reference Manual?”
This manual, over time, needs to develop into a pure reference manual where all procedural information
eventually ends up in an appropriate guide.
A good example of information perfect for the Poky Reference Manual is the appendix on variable
definitions (glossary).

<para>
Welcome to the Yocto Project Development Manual!
This manual gives you an idea of how to use the Yocto Project to develop embedded Linux
images and user-space applications to run on targeted devices.
Reading this manual gives you an overview of image, kernel, and user-space application development
using the Yocto Project.
Because much of the information in this manual is general, it contains many references to other
sources where you can find more detail.
For example, detailed information on Git, repositories and open-source in general
can be found in many places.
Another example is how to get set up to use the Yocto Project, which our Yocto Project Quick Start covers.

<para>
Text needed here.
Application development involves creation of an application that you want to be able
to run on your target hardware, which is running a Linux Yocto image.
The Yocto Project provides an Application Development Toolkit (ADT) that
facilitates quick development and integration of your application into its run-time environment.
Using the ADT you can employ cross-development toolchains designed for your target hardware
to compile and link your application.
You can then deploy your application to the actual hardware or to the QEMU emulator for testing.
If you are familiar with the popular Eclipse IDE, you can use an Eclipse Yocto Plug-in to
allow you to develop, deploy, and test your application all from within Eclipse.
</para>
<para>
While we strongly suggest using the Yocto Project ADT to develop your application, you might
not want to.
If this is the case, you can still use pieces of the Yocto Project for your development process.

WRITER NOTE: The areas to get the kernel and root filesystem are located in the Index of
downloads. There are many forms of each. The files that have "rootfs" are just the
target root filesystems. The file that is very small and starts with bzImage is just
the kernel image isolated so that it can be written to a special on-board area of
flash memory. Some systems require this. In the machines directory there are
files that combine the kernel image and the root filesystem. These files are the ISO
and HDDIMG files. ISO images are designed to be deployed on a DVD or CD. The ISO
images are designed to be deployed on a USB stick. There might be some relics in
the machine directory. For example, there is the "emenlow-bernard-5.0.0.tar.bz2"
file. Nobody seems to know what this is. If a developer needs the image and the
root filesystem I think that they want the small kernel image and a matching root
filesystem. Although, Paul Eggleton says that the HDDIMG types could be used to
develop on. I am not sure that we can use one of those in the ADT though as they
want you to point to the kernel image and the target root filesystem. Maybe you
could just point to the same spot. I am not sure.

When you submit a change or patch to the Yocto Project, you must follow certain procedures.
In particular, the headers in patches and the commit messages must follow a certain standard.
The general process is the same as described earlier in this chapter.
For complete details on how to create proper commit messages and patch headers see
[WRITER NOTE: I need the link to Mark's wiki page here that describes the process.]
When you form a commit, you must follow certain standards established by the
Yocto Project development team.
For each commit, you must provide a single-line summary of the change and you
almost always provide a more detailed description of what you did (i.e. the body
of the commit).
The only exceptions for not providing a detailed description would be if your
change is a simple, self-explanatory change that needs no description.
Here are the Yocto Project commit message guidelines:
<itemizedlist>
<listitem><para>Provide a single-line, short summary of the change.
This summary is typically viewable by source control systems.
Thus, providing something short and descriptive that gives the reader
a summary of the change is useful when viewing a list of many commits.
</para></listitem>
<listitem><para>For the body of the commit message, provide detailed information
that describes what you changed, why you made the change, and the approach
you used.
Provide as much detail as you can in the body of the commit message.
</para></listitem>
<listitem><para>If the change addresses a specific bug or issue that is
associated with a bug-tracking ID, prefix your detailed description
with the bug or issue ID.
For example, the Yocto Project tracks bugs using a bug-naming convention.
Any commits that address a bug must start with the bug ID in the description
as follows:
<literallayout class='monospaced'>
YOCTO #&lt;bug-id&gt;: &lt;Detailed description of commit&gt;
</literallayout></para></listitem>
</itemizedlist>

MULTILIB_IMAGE_INSTALL = "lib32-connman"
</literallayout>
This example enables an
additional library named <filename>lib32</filename> alongside the
normal target packages.
When combining these "lib32" alternatives, the example uses "x86" for tuning.
For information on this particular tuning, see
<filename>meta/conf/machine/include/ia32/arch-ia32.inc</filename>.
</para>
<para>
The example then includes <filename>lib32-connman</filename>
in all the images, which illustrates one method of including a
multiple library dependency.
You can use a normal image build to include this dependency,
for example:
<literallayout class='monospaced'>
$ bitbake core-image-sato
</literallayout>
You can also build Multilib packages specifically with a command like this:
<literallayout class='monospaced'>
$ bitbake lib32-connman

A list of run-time dependencies for a package.
These packages need to be installed alongside the package to which
they apply.
This enables the package to run correctly.
For example, consider a Perl script, which depends on the Perl package.
Since this variable applies to
output packages, there would usually be an override attached
to this variable such as <filename>RDEPENDS_${PN}-dev</filename>.
Names in this field must appear as they appear in the
A list of packages that must be installed as part of a package being built.
The package being built has a runtime dependency on the packages in the
variable's list.
In other words, in order for the package being built to run correctly,
it depends on these listed packages.
If a package in this list cannot be found during the build, the build
will not complete.
</para>
<para>
Because the <filename>RDEPENDS</filename> variable applies to packages
being built, you should
always attach an override to the variable to specify the particular runtime package
that has the dependency.
For example, suppose you are building a development package that depends
on the <filename>perl</filename> package.
In this case, you would use the following <filename>RDEPENDS</filename>

$libdir isn't used by the Makefile at all apart from in this mkdir.
This will be used without any DESTDIR so if your libdir is a different
layout to the bulid system it will cause a failure. E.g:
Build system has /usr/lib only
libdir = /usr/lib64 for the target
Results in "mkdir: cannot create directory `/usr/lib64': Permission denied"
Since the directory is never used, we can just remove the mkdir.

Save registers via local variables instead of simple "push", so that gcc become
aware of this operation and avoid stack disorder.
opengl calling (in call_opengl_qemu) includes 4 steps:
1. prepare opengl parameters on stack
2. save some "input" register by push
3. load "input" register with parameters on stack via same index as step 1
4. issue "int 0x99" to trap into qemu, who will get parameter in the registers
New gcc uses "%esp" rather than "%ebp" to index local variable in stack, which
leads wrong index in step 3, as push decrease "%esp" automatically. Saving
registers via local variables to fix it.
