Trouble with dom0 and domU compilation

Trouble with dom0 and domU compilation

[James Rhett Aultman]

Xen developers,

I've been trying to compile the source for xen Linux dom0 and domU
kernel images from source, and I'm getting a compile time error I don't
know how to fix:

arch/i386/kernel/process.c: In function `cpu_idle':
arch/i386/kernel/process.c:195: error: `cpu' undeclared (first use in
this function)

this is for the xen0 and xenU of linux-2.6.12

Advice appreciated

Rhett.

Specify ARCH=xen (ARCH=xen make <target>).

Hm...that gets around one problem, but now I seem to have another build
failure:

/bin/sh: line 1: arch//kernel/asm-offsets.s: No such file or directory
  UPD   include/asm-xen/asm_offsets.h
Mv: cannot stat `include/asm-xen/asm_offsets.h.tmp': No such file or
directory
make: *** [include/asm-xen/asm_offsets.h.tmp] Error 1

Did you do a make config of some sort?

Actually, yes.  When I saw the build error over "cpu", I ran a make
menuconfig to remove SMP support.

I would just start over with a fresh "make world". If you have local options
you want add them to the defconfig in the sparse tree beforehand.

I saw similar problems after accidently runing make with the prevailing
arch (i386) instead of ARCH=xen. Blowing everything away and running
make world resolved the problem as you suggest. I lost interest in
trying to track down how the build might be made less fragile.
