Linux Kernel Cross-Compiling question

Linux Kernel Cross-Compiling question

[Jerry Wang]

Hi,

I am trying to cross-compile the linux 2.6.11.1 kernel on
i686 vm for ppc, and I've been getting the following
errors. Has anyone had this issue before?

Thanks,
Jerry

Why are you trying to compile something that is /so/ old? Please
re-test with a current GIT snapshot.

Can you post the command you used to genberate the .config and build the
kernel.  Also what is version of your powerpc binutils and gcc?

I assume you need 2.6.11.1 for some reason and newer kernels are out of the
question?
