There is a Makefile for you in attachment.
Here is lsmod output:
It's work :)
[root@Sombre lkm]# lsmod
Module Size Used by
main 836 0 (unused)
NVdriver 660144 15 (autoclean)

Top line:
#define __KERNEL__
... compiles without any errors, one warning about an unused variable.

Penguin : Linux version 2.4.1 on an i686 machine (799.53 BogoMips).
I was going to compile a list of innovations that could be
attributed to Microsoft. Once I realized that Ctrl-Alt-Del
was handled in the BIOS, I found that there aren't any.
Hi-
I'll suggest a few things for you.
cd to your linux tree and 'make modules'
Look at the gcc compile string there.
Try to copy it closely.
I added -I/path/to/linux/include and -D__KERNEL__
and compiled your module with no problem.
If you had included the complete messages, we could have
seen that it was using /usr/include/linux for header files
instead of header files from linux/include/* .
(at least that's what it did on my system)
