AVR Freaks

Hi

I'm instal the lastest version of Atmel Studio from the atmel.com
I'm trying to make a very simple program but i can't !!

#include <avr/io.h>


int main(void)
{
    /* Replace with your application code */
    while (1) 
    {
    }
}

The Problem(Error) is:  

recipe for target 'main.o' failed
