Please can some one suggest what could be the problem?
Here is is the program:
##############################
#include<linux/fs.h>
#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/init.h>

MODULE_LICENCE("GPL")

static int initialization(void)
{
printk("Hello world\n");
}

static void clean_up(void)
{
printk("Clean up\n");
}

module_init(initialization);
module_exit(clean_up);

It was typing error when i posted, The error i was getting because of different reason i felt, when i analyzed.
I installed Fedora-6 Linux, where i need to install kernel-devel package separately.

This link talks about the installation package.
Fedora Project, sponsored by Red Hat

2) It was not having this problem with earlier version of Fedora.
Thank you for your help Venkat.

thanks
