problem with compiling a simple module


hello everybod, i wanted to compile a simple module on my suse box 9.0 kernel 2.4.21-99, but it did nott work.

I don't know what's the problem(quite a newby), I looked in several forum for similar threads but nobody could answer my question.

this is the module example:
#define MODULE
#include <linux/module.h>

int init_module(void) { printk("<1>Hallo, Welt\n"); return 0; }
void cleanup_module(void) { printk("<1>Ade, du grausame Welt\n"); }


and when I compile it with
gcc -c hello.c i get the following:
Z626:/home/igor # gcc -c hello.c
