Cześć

I wrote a simple kernel module

#define MODULE
#include <linux/module.h>

int init_module(void){
     printk("Witaj świecie\n");
     return 0;
}

void cleanup_module(void){
     printk("Żegnaj świecie\n");
}

I was compile that by gcc -c -D__KERNEL__ hello.c -Wall
-I/usr/src/linux/include

System running on exactly the same kernel (manually rebuild and install
for sure) as kernel headers which was used to compilation.

Module was compile ok without any errors or warnings.

When I try to load that module insmod show error message:

# insmod hello.o
insmod: unresolved symbols

What should I do to run that simply module ?
