RE: [Xen-users] Re: [Xen-devel] need to compile 32bit on x86_64 cpu
You need to clean the linux kernel directory (probably with
"mrproper" note: mrproper will remove your .config file too, so copy that if you
have made any changes...)

Reading the README i found a way to do this
export
XEN_TARGET_ARCH=i386
or
export
XEN_TARGET_ARCH=x86_32
Then do
make linux-2.6-xen-config
CONFIGMODE=menuconfig
Now menuconfig shows the 32bit cpu's. However
when i run the build command, it fails badly giving the following errors:
make -f buildconfigs/mk.linux-2.6-xen build
make[1]: Entering
directory `/home/xen/xen-3.0.2-2'
if grep "^CONFIG_MODULES="

make -C

My guess is that its complaining about some libraries for
32bit and since the os is 64bit, they are not present.
Can anyone
please shed more light on this ?
Thanks.
