Help!How to solve this error-about module.h missing problem
 

I am a biginner in module programming, and I'm trying to study the module programming by some examples, so I got a simple copy as follow:
////////////////////
//test.c

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

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

int init_module()
{
printk("Hello!This is testing module");
return 0;
}

void cleanup_module()
{
printk("Sorry!The testing module is unloading now!");
}
//end of the program
/////////////////////
after I compiled it by command:

[root@localhost tian]# gcc -O2 -Wall -DMODULE -D__KERNEL__ -c test.c
test.c:2:26: error: linux/module.h: No such file or directory
test.c: In function 鈏nit_module?
test.c:11: warning: implicit declaration of function 鈖rintk?

I have checked for many comments, still not solved
and I need your help for that and I will much appreciate of you

You might be missing a package called linux-headers or kernel-headers depending
on your distro.
'linux/module.h' will be in /usr/include/
A nice thing to do, is to put the name of your distro into your profile here at LQ.
