Hi all,

I am in the initial hard steps of learning the nuances of kernel programming, as to begin what are all the modules (header files) to use its data-structures be included to go about, as I tried this source:
src: http://tldp.org/LDP/lkmpg/2.6/html/x121.html
/*
* hello?1.c ? The simplest kernel module.
*/
#include <linux/module.h>
/* Needed by all modules */
#include <linux/kernel.h>
/* Needed for KERN_INFO */
int init_module(void)
{
    printk(KERN_INFO "Hello world 1.\n");
/*
* A non 0 return means init_module failed; module can't be loaded.
*/
    return 0;
}
void cleanup_module(void)
{
    printk(KERN_INFO "Goodbye\n");
}

as compilation followed this:
box at x86:~$ cc kernel_hello.c 
kernel_hello.c:3: fatal error: linux/module.h: No such file or directory
compilation terminated.

Thanks and Regards,
Srinidhi.
