my first program compiling error

hi, i just wanted to start programming arm, i got an LPC1768 board ! i wrote my first program !

here is code

#include "LPC17xx.h"

int main(void)
{
        int a;
        LPC_GPIO1->FIODIR=1;

        while(1)
        {
                LPC_GPIO1->FIOSET=1;
                for(a=0;a<7200000;a++);
                LPC_GPIO1->FIOCLR=1;
                for(a=0;a<7200000;a++);
        }
}

it says :

Rebuild target 'Target 1'
assembling startup_LPC17xx.s...

also if i create it , im not sure how to make it a bin file, my board manual says i must covert it to bin with -H!
