Hi,
I was spending some spare cycles on
https://github.com/koenkooi/meta-archos and wanted to build the 2.6.22
vendor kernel first before trying to the 3.0rc working and I need to use
csl 2007q3 as gcc-cross-kernel due to bugs in the kernel.
I imported the 2008q1 recipes from OE-core, then changed the SRC_URI to
have the patches from the 2007q3 recipe in OE classic. It uses the .inc
files from OE-core. It builds and gives me:
koen@dominion:/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/work/armv7a-angstrom-linux-gnueabi/gcc-cross-kernel-4.2.1-4.2.1+csl-arm-2007q3-53-r0/image$
find . | grep bin

But when I do 'MACHINE=archos5 bitbake virtual/kernel -c compile' I get:

| arm-angstrom-linux-gnueabi-gcc-4.2.1+csl-arm-2007q3-53: No such file
or directory
And I can't find arm-angstrom-linux-gnueabi-gcc-4.2.1+csl-arm-2007q3-53
in sysroots. When looking at WORKDIR for the gcc:
koen@dominion:/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/work/armv7a-angstrom-linux-gnueabi/gcc-cross-kernel-4.2.1-4.2.1+csl-arm-2007q3-53-r0$
find sysroot-destdir/ | grep bin
sysroot-destdir/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/sysroots/x86_64-linux/usr/bin
sysroot-destdir/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/sysroots/x86_64-linux/usr/bin/armv7a-angstrom-linux-gnueabi.gcc-cross-kernel-4.2.1
sysroot-destdir/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/sysroots/x86_64-linux/usr/bin/armv7a-angstrom-linux-gnueabi.gcc-cross-kernel-4.2.1/arm-angstrom-linux-gnueabi-gcov
sysroot-destdir/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/sysroots/x86_64-linux/usr/bin/armv7a-angstrom-linux-gnueabi.gcc-cross-kernel-4.2.1/arm-angstrom-linux-gnueabi-gccbug
So that's missing the
arm-angstrom-linux-gnueabi-gcc-4.2.1+csl-arm-2007q3-53 that's actually
needed.
in oe-core we munge CROSS_TARGET_SYS_DIR and append PN to it, this
should be considered in gcc-cross-kernel.inc
you need couple of changes
change the install command like below in gcc-cross-kernel.inc
install -m 0755 xgcc
${D}${STAGING_DIR_NATIVE}${prefix_native}/bin/${TARGET_PREFIX}gcc-${PV}
secondly you need to inform kernel recipe of this new location of toolchain
so in you kernel recipe somewhere patch the below code
PATH_prepend = "${STAGING_BINDIR_TOOLCHAIN}.gcc-cross-kernel:"
Thanks
