LINUX Modules

[vinot85]

I have worked with this program of inserting a module to LINUX Kernel.
/*hellomodule.c*/
#define MODULE

int init_module(void){
printk("<1>Hello Module\n");
return 0;
}

void cleanup_module(void){
printk("<1>Goodbye\n");
}

I compiled the program with command

root# gcc -c hellomodule.c

I got the ouput file as hellomodule.o

And i failed in using the command,

root# insmod ./hellomodule.o

It is showing an error,

The file is not in module format and No module formats.

Whether we have any specific directories to put this modules?
How can i successfully install a module to the kernel?
Im using REDHAT EL - 4
