Hi, I am sorry about the lack of information in this email, I was in a

I want to compile a kernel a new kernel with a frame buffer for a X5000, 
because I was going to reinstall it anyway. Less that I have to do on 
the X5000 with a serial console.

To cross compile I used:
make buildkernel TARGET_ARCH=powerpc64 KERNCONF=AMIGAX5000

Is there something else that is needed to make this compile?

I was able to build a working kernel and userland before on the G3 and 
then recompile everything on the X5000. It maybe that my hard drive has 
failed.

Please let me know if you need other information.

Thanks,
