Compiling against different kernel

Compiling against different kernel

[Ed W]

Hi, I am building a kernel for an embedded 32bit x86 kernel on my x86_64 
machine.  I have a 32bit x86 build environment in a chroot, but 
obviously "uname" still looks like the host

I try to compile compat-wireless (2009-08-24) like this:

make ARCH=x86 KLIB=/usr/src/linux-2.6.30.5-grsecurity-2.1.14-aufs/ 
KLIB_BUILD=/usr/src/linux-2.6.30.5-grsecurity-2.1.14-aufs/

I get:

FATAL: Could not load 
/lib/modules/2.6.29.6-grsec2.1.14-vs2.3.0.36.14/modules.dep: No such 
file or directory
FATAL: Could not load 
/lib/modules/2.6.29.6-grsec2.1.14-vs2.3.0.36.14/modules.dep: No such

./scripts/gen-compat-autoconf.sh config.mk > include/linux/compat_autoconf.h
FATAL: Could not load

make -C /usr/src/linux-2.6.30.5-grsecurity-2.1.14-aufs/ 
M=/usr/src/compat-wireless-2009-08-24 modules
..etc..

(where it's clearly trying to find the modules dir for the running 64bit 
kernel, rather than the
I'm looking through the makefile, but I can't see how it's trying to 
adapt depmod to use the correct modules.dep?

Can someone please help with the correct incantation to cross compile?

Thanks
