Problemer med at compile HelloModule eksempel på linux

Jeg forsøger at compile følgende eksempel modul:
#include <linux/init.h>
#include <linux/module.h>
MODULE_LICENSE("GPL");

static int __init driver_init(void)
{
    printk("Driver eksempel - Init");
    return 0;
}

static void __exit driver_exit(void)
{
    printk("Driver eksempel - Exit");
}

module_init(driver_init);
module_exit(driver_exit);

MODULE_AUTHOR("THR");
MODULE_DESCRIPTION("Et simpelt eksempel");

Og compiler filen med: gcc -o ExMod Eksempel.c

men får en masse fejl fra kode jeg ikke har skrevet.
Hvor kan fejlen stamme fra?

Udklip af fejlene:
[root@udvikling src]# gcc -o driver Eksempel_Driver.c
