How compile a file from 32to64bit (Syscall?)

[linuxverbrezler]

Hi Sorry about my terrible english,
i want to compile au Prog form 32bit to 64 bit,
and i dont know what to do :/

Can you help me! ? Here is the Code:


#include <stdio.h>
#include <linux/unistd.h>
#include <errno.h>
main ()
{
printf("Berechnung nach Gauß Formel \n");
printf("Die Summe ist: %d \n", syscall(320) );
}


(its the Code for 32 Bit)
and needed for 64bit......

By default, if you build it on a 64-bit system, it will generate 64-bit code. So, what exactly is your problem?
