[64studio-devel] Problem compiling kernel module for SMP

[Larry Troxler]

Hi,

I'm trying to compile a kernel module for 2.6.17 AMD-64 SMP from source 
(an imon_vfd module for a media center display). I have the 
linux-headers-2.6.17-1-multimedia-amd62-k8 and 
linux-headers-2.6.17-1-multimedia-amd62-k8-smp installed.

When I modprobe the module, it fails because the version magic for the 
module I built doesn't have "SMP" in it :

 >>
imon_vfd: version magic '2.6.17-1-multimedia-amd64-k8-smp preempt 
mod_unload gcc-4.1' should be '2.6.17-1-multimedia-amd64-k8-smp SMP 
preempt mod_unload gcc-4.1'
<<

Investigating, I found that the autoconf.h in the smp kernel headers is 
a symbolic link to the non-smp headers :

ls -l autoconf.h
lrwxrwxrwx 1 root root 67 2007-01-28 22:37 autoconf.h -> 
../../../linux-headers-2.6.17-1-multimedia/include/linux/autoconf.h
<<

This autoconf.h doesn't have SMP defined (#undef CONFIG_SMP) and I'm 
guessing that this is my problem.

Is this a bug in the packages, or am I doing something wrong? Can I 
simply change the autoconf.h file and rebuild, or is there more to it 
than that?

Thanks
