hello every one
please can any one suggest to me a powerpc cross compiler package or from
source, i have downloaded cross compiler package such as powerpc64le and i
got a little endian and big endian problem, i have tried also to download
eldk cross compiler but i didn't know how
any suggestion please
regards,

thanks for replying, I tried a powerpc cross compiler from the list you
have send but I always got this error
VDSO32L arch/powerpc/kernel/vdso32/vdso32.so.dbg

If you're on Ubuntu:
$ sudo apt-get install gcc-powerpc-linux-gnu gcc-powerpc64le-linux-gnu libc-dev-powerpc-cross libc-dev-ppc64el-cross
On Fedora I think it's called gcc-powerpc64-linux-gnu.
Then to build a big endian kernel:
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- mrproper
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- ppc64_defconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -j 4
To build a little endian kernel:
$ make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- mrproper
$ make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- ppc64le_defconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- -j 4
cheers

This kind of error is usually caused by building for one endianess
then changing endianness in the kernel configuration. The build system
isn't smart enough to realise that it needs to recompile the VDSO when
this happens so you'll get linker errors unless you clean the build
directory with `make mrproper` or similar.
We should probably fix that.
