Makefile error

[GoogleCodeExporter]

Tried to run 'make all' command, but produced the following error/s:

kgpu-8-1-2011/kgpu/kgpu_kutils.c: In function ‘kgpu_virt2phy’:
kgpu-8-1-2011/kgpu/kgpu_kutils.c:70:5: error: implicit declaration of function 
‘kmap_atomic’

I'm trying to install kgpu-8-11-2011 (the latest, I think). These are the info 
from my kernel/CPU:
Linux 2.6.38-11-generic #48-Ubuntu SMP i686 i686 i386 GNU/Linux

I'm not sure if my CPU is 32-bit or 64-bit, but based on /proc/cpuinfo, tm and 
lm flags are present.

Is the error from 'make all' is because I'm using a 32-bit Linux kernel? Thanks.

Yes, you are using a 32bit kernel, which KGPU doesn't support.

If you could use a 64bit one, please get the latest kgpu code from github, 
current supported kernel is 2.6.39.4. It is better to use your own compiled 
kernel rather than the one shipped with your distribution.

I've reinstalled 64-bit Ubuntu 11.04 and tried to install kgpu-9-12-2011. I've 
run 'make all' command but produced the following error/s:

I've located stdarg.h and had these results:

/usr/include/c++/4.5/tr1/stdarg.h
/usr/lib/syslinux/com32/include/stdarg.h
/usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/include/cross-stdarg.h
/usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/include/stdarg.h

What seems to be the problem here? We need to make this work for our project. 
Thanks!

link /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/include/stdarg.h
to the include/ folder in your kgpu
