osx snow leopard

I'm trying to compile my first linux ARM hello world program and when I copy and run the binary to my target linux board (linuxstamp Atmel arm 9g20) I get "Illegal instruction"

I am running arm-elf-gcc-4.6 on OS X from macports. I am using Eclipse for and IDE. It looks like the build is more for a stand alone non OS program rather then code to run in linux user space. Could someone point me in the right direction? Thanks.

code:

#include<stdio.h>

int main(){
    printf("hello worldn");
    return 0;
}

Indeed, this is for embedded ARM devices without Linux OS. The Linux variant of gcc as cross compiler for ARM should have "linux" somewhere in its name like "arm-linux-gcc".
