Re: [linux-audio-dev] Cross compiling the kernel

(I apologise if anyone finds this thread OT, it is relevant to Linux
audio development and the kernel people don't want to hear about
toolchain problems)

Hmm, now I am getting somwhere. I had failed to run "make mrproper" so
include/asm was still symlinked to include/asm-i386. After fixing that,
I got a bit farther.

  LD usr/built-in.o
ld: warning: i386 architecture of input file `usr/initramfs_data.o' is incompatible with i386:x86-64 output

This one is worrisome, maybe I also need to pass LDFLAGS?

  CC arch/x86_64/kernel/process.o
  CC arch/x86_64/kernel/signal.o
  AS arch/x86_64/kernel/entry.o

Assembler problem?

So it looks like my GCC is OK but the assembler and linker still are not
happy. Any ideas?
