gcc & kernel mismatch

I'm trying to learn about device driver programming by compiling a simple program under gcc. The program compiles fine but when I try to load the module using insmod I get the following error:

/home/jason/driver.o : kernel- module version mismatch
/home/jason/driver.o was compiled for kernel version 2.4.20
while the kernel is version 2.4.20-28.9

How can I fix this problem? Any help woud be greatly appreciated.

Well might edit the Makefile and make the driver think it was compiled with kernel 2.4.20-28.9

it is Open Source, so hack away........

Maybe you included the wrong set of kernel-headers?
i.e. gcc -I/usr/src/linux-2.4.20-28.9

Hey 320mb,

You responded to my post about a kernel mismatch. Your suggestion was to edit the makefile. I was able to get around my original problem but am curious as to how I could have done what you suggested. Ho do I edit a makefile. Where is it?

Your help would be appreciated.
