[OE-core] sdk path problem

[James Limbouris]

Hi,

I have been using meta-toolchain-qte in the past to cross compile a Qt app, and the Linux kernel.
Recently I replaced my old SDK image with a fresh one, and found that I could not link vmlinux anymore.

When building the kernel, I use the following ('rica' is the distribution name):
export PATH=$PATH:/usr/local/rica-eglibc-i686-armv5te/sysroots/i686-ricasdk-linux/usr/bin/armv5te-rica-linux-gnueabi/
make ARCH=arm CROSS_COMPILE=arm-rica-linux-gnueabi- zImage

The new error message is:

Kernel: arch/arm/boot/Image is ready
  AS      arch/arm/boot/compressed/head.o
  GZIP    arch/arm/boot/compressed/piggy.gz
  CC      arch/arm/boot/compressed/misc.o
  AS      arch/arm/boot/compressed/piggy.o
  LD      arch/arm/boot/compressed/vmlinux
arm-rica-linux-gnueabi-ld: cannot find libgcc.a: No such file or directory

Comparing the build with the old sdk to the build with the new one, I find that the command line for linking has changed from:

arm-rica-linux-gnueabi-ld -EL --defsym zreladdr=0x80008000 --defsym initrd_phys=0x80800000 --defsym params_phys=0x80000100 -p --no-undefined -X /usr/local/rica-eglibc-i686-armv5te/sysroots/arm-rica-linux-gnueabi/usr/lib/arm-rica-linux-gnueabi/4.5.4/libgcc.a -T arch/arm/boot/compressed/vmlinux.lds arch/arm/boot/compressed/head.o arch/arm/boot/compressed/piggy.o arch/arm/boot/compressed/misc.o -o arch/arm/boot/compressed/vmlinux

to:

arm-rica-linux-gnueabi-ld -EL --defsym zreladdr=0x80008000 --defsym initrd_phys=0x80800000 --defsym params_phys=0x80000100 -p --no-undefined -X libgcc.a -T arch/arm/boot/compressed/vmlinux.lds arch/arm/boot/compressed/head.o arch/arm/boot/compressed/piggy.o arch/arm/boot/compressed/misc.o -o arch/arm/boot/compressed/vmlinux

So libgcc.a has lost its path qualification.
I also straced the two linker commands, and found that they differed in one sequence.

Old:
lstat64("/usr/local/rica-eglibc-i686-armv5te", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/usr/local/rica-eglibc-i686-armv5te/sysroots", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/usr/local/rica-eglibc-i686-armv5te/sysroots/arm-rica-linux-gnueabi", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0

New:
lstat64("/usr/local/rica-eglibc-i686-armv5te", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/usr/local/rica-eglibc-i686-armv5te/sysroots", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/usr/local/rica-eglibc-i686-armv5te/sysroots/arm-rica-linux-gnueabi", 0xbffe67cc) = -1 ENOENT (No such file or directory)

Both toolchains are looking for a sysroot at 'arm-rica-linux-gnueabi', but the new toolchain should be looking at 'armv5te-rica-linux-gnueabi', as the names have changed.
I'm not yet acquainted with the darker arts of toolchain generation. Can anyone help with this?
