Hi All,

I just cut and paste a very simple module program (using C).

#ifndef __KERNEL__
# define __KEREL__
#endif
#ifndef MODULE
# define MODULE
#endif
#ifndef __NO_VERSION__
# define __NO_VERSION__
#endif

#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/init.h>

static char __initdata hellomessage[] = "hello world";
static char __exitdata bymessage[] = "good bye";

static int __init start_hello_world(void)
{
printk(hellomessage);
}

static void __exit go_awa(void)
{
printk(byemessage);
}

module_init(start_hello_world);
moudle_exit(go_away);

When i compile it, i get this mesage.

example.o was compiled for kernel version 2.4.20 while this kernel is version 2.4.20-8.

I've been surfing the net for answers and i'm getting the impression that i will have to re-compile my kernel and modify the make file to take away version (ie. change 2.4.20-8 to 2.4.20).

Is this the only way? I am really stumped with this.

Thanks.

sorry. afer reading my email i made mistake.

Compiling is ok. Its just when i run this comamnd: /sbin/insmod , i get this error message.

example.o was compiled for kernel version 2.4.20 while this kernel is version 2.4.20-8.

The version string encoded in one of the linux headerfiles doesnt match the kernel version. I think its in /usr/include/linux/version.h, but dont have linux kernel; src at hand. Run grep on it looking for 'version' and 'VERSION'. If you find a macro definition for the function, you can just pass the -Dmacroname=value to gcc, otherwise edit the header itself.

For module compile info, get Rubini's book Linux Device Drivers, chapters 1&2 (I believe) (visit O Reilly site for free sample), or get the Linux Kernel Module Programmers Guide (LKMPG, free though a bit dated, www.tldp.org)

awsome, thanks!

in the version.h file i changed the UTS_RELEASE macro and that seem to work.

thanks
