Hi,

I am trying to learn kernel module programming and i'm using the the linux kernel module programming guide. But i cannot even successfully compile the hello world program. The compiler posts a message like " Warning : Kernel version mismatch. The module has been compiled for kernel version 2.4. while this kernel version is 2.2.16".

Please tell me how to compile a module without version dependencies..

Regards,

Thomas

the kernel version shouldn't defined anywhere in the module - it should have headers to do that.

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

#if CONFIG_MODVERSIONS==1
#define MODVERSIONS
#include <linux/modversions.h>
#endif

int init_module()
{
printk("hello world\n");
return 0;
}

void cleanup_module()
{
}

--- and, that's it for the hello world. it needs to be compiled with

CC=gcc
MODCFLAGS := -Wall -DMODULE -D__KERNEL__ -DLINUX

hello.o: hello.c /usr/include/linux/version.h
$(CC) $(MODFLAGS) -c hello.c



it doesn't do anything, but it should load and unload.
