I am writing kernel programs..
i need to compile those things..

kernel programs are not modules...

i want to use basic level functions.....

How to compile programs is my doubt..

dont say u cant compile programs
we can compile becoz using some options in gcc we can able to recompile kernel

so , what options i have to include to gcc so that i can compile kernel programs

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

int main(){
printk (KERN_INFO ""THIS IS SUBBU");
printk(KERN_DEBUG "how r u??");
return 0;
}

i want to compile and execute this program

how ???

You just need to read tutorials... There are many books about it!
eg. http://www.xml.com/ldd/chapter/book/ --> linux device driver if you didn't want to write any kernel driver, kernel programming isn't for you!

there is a third edition: http://lwn.net/Kernel/LDD3/

There is no such thing as a kernel program. You cannot execute a program in kernelspace. However, you can access kernel modules from userspace. Perhaps this is what you mean.
