Have you tried gcc -o hello hello.c? That's the usual order, but I tried it on my machine and your order does seem to work.

Make sure you have the file "/usr/include/stdio.h"

and it looks like you're missing a space in your include statement, it should be:

Code:

#include <stdio.h>

I copied and pasted your code into a file and got a completely different error. This is a known working standard hello.c program, copy and paste it into a new .c file and try it and report back:

use "gcc -o hello whateverfilenameyouuse.c"

Code:

#include <stdio.h>

int main (int argc, char * argv[]) {

	printf("Hello World!\n");
	return 0;
}

(BTW: This probably should be in the Programming forum)

OK, great.

Since you've solved your problem, you should change the title of your post to put "[SOLVED]" in front of it.

Hi,

Just to clear up any possible confusion. One does not edit their thread title to do this. Instead you use the Thread Tools pulldown menu and mark your thread as Solved. The OP has this capability. And they have correctly done this.
