If we are building from sstate-cache it's possible to be building from another folder on another machine, therefore the linker requires that a proper --sysroot is passed too it so it can find things like libgcc.a and avoid errors such as: | arm-poky-linux-gnueabi-gcc -g -O2 -fno-common -ffixed-r8 -msoft-float -D__KERNEL__ -DCONFIG_SYS_TEXT_BASE=0x80008000 -I/local/yocto/upstream/label/ubuntu1204-64b/machine/beagleboard/poky/edison/tmp/work/beagleboard-poky-linux-gnueabi/u-boot-v2011.06+git5+b1af6f532e0d348b153d5c148369229d24af361a-r0/git/include -fno-builtin -ffreestanding -nostdinc -isystem /local/yocto/upstream/label/ubuntu1204-64b/machine/beagleboard/poky/edison/tmp/sysroots/x86_64-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi/../../lib/armv7a-vfp-neon-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.6.3/include -pipe -DCONFIG_ARM -D__ARM__ -marm -mabi=aapcs-linux -mno-thumb-interwork -march=armv5 -Wall -Wstrict-prototypes -fno-stack-protector -fno-toplevel-reorder -o hello_world.o hello_world.c -c | arm-poky-linux-gnueabi-gcc -g -O2 -fno-common -ffixed-r8 -msoft-float -D__KERNEL__ -DCONFIG_SYS_TEXT_BASE=0x80008000 -I/local/yocto/upstream/label/ubuntu1204-64b/machine/beagleboard/poky/edison/tmp/work/beagleboard-poky-linux-gnueabi/u-boot-v2011.06+git5+b1af6f532e0d348b153d5c148369229d24af361a-r0/git/include -fno-builtin -ffreestanding -nostdinc -isystem /local/yocto/upstream/label/ubuntu1204-64b/machine/beagleboard/poky/edison/tmp/sysroots/x86_64-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi/../../lib/armv7a-vfp-neon-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.6.3/include -pipe -DCONFIG_ARM -D__ARM__ -marm -mabi=aapcs-linux -mno-thumb-interwork -march=armv5 -Wall -Wstrict-prototypes -fno-stack-protector -fno-toplevel-reorder -o stubs.o stubs.c -c | arm-poky-linux-gnueabi-ld -r -o libstubs.o stubs.o | arm-poky-linux-gnueabi-ld -g -Ttext 0x80300000 \ | -o hello_world -e hello_world hello_world.o libstubs.o \ | -L. -lgcc | arm-poky-linux-gnueabi-ld: cannot find -lgcc | make[1]: *** [hello_world] Error 1 (From OE-Core rev: ad78441045183277a7e77341f4af6d9d65a4a3c8) Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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: http://yoctoproject.org/community/documentation
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 = "") and contains only emulated machine support.
