module compilation
i am trying to compile a simple hello module but when i write
gcc -c -Wall hello.c
then i get
warning: implicit declaration of function "printk"
so where is the wrong , thanx for helps
/* hello.c */
#define MODULE
#include <linux/module.h>
int init_module(void) {printk("<1>hello\n"); return 0; }
void cleanup_module(void) {printk("<1>goodbye\n");}
