[SOLVED] crt1.o error when trying to compile

Hi everybody,
I'm trying to compile a simple rtnetlink example written in c using gcc [ver 4.7.2] but I get this error :

/usr/lib/gcc/x86_64-unknown-linux-gnu/4.7.2/../../../../lib/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status

and here is the include parts of example :

#include <sys/socket.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <linux/netlink.h>
#include <linux/rtnetlink.h>
#include <arpa/inet.h>
#include <unistd.h>

Should I add a specific library or something ?! (I tried netlink and pthreads libraries and it didn't work)

thanks in advance

@bahramwhh We'll need to complete source code and the exact compiler and link invocation to help you.
