How to compile a kernel

I am trying to compile a linux-ck kernel from AUR, but I encounter an issue:

...
  UPD     include/generated/uapi/linux/version.h
  UPD     include/generated/utsrelease.h
  CC      scripts/mod/empty.o
cc1: error: code model 'kernel' not supported in the 32 bit mode
cc1: sorry, unimplemented: 64-bit mode not compiled in
make[1]: *** [scripts/Makefile.build:271: scripts/mod/empty.o] Error 1
make: *** [Makefile:1218: prepare0] Error 2
==> ERROR: A failure occurred in build().
    Aborting...

Is there a way to compile a kernel on a 32bit machine? And while I am at it - what would be the optimal one for a Pentium M?

Re: How to compile a kernel

Certainly it used to be easy; just download the source, cd into it and make.  But those cc errors don't look like the normal gcc errors I expeirience, so without loking at the build rule for linux-ck I can't say.

Isn't Linux-CK strictly only for 64-bit Intel/AMD CPUs?

And cross-compiling from 32-bit IA-32 to 64-bit x86_64 is not supported..

Re: How to compile a kernel

Certainly it wouldn't surprise me if some of the patches provided speedups by using x86-64 instructions, but I have no positive evidence of that.  Maybe those errors are indicating as much though, I'm not sure.
