We're going to need a lot more information that you just gave us. A listing of the code would be particularly helpful, as would the exact gcc command line you're using.

frustration....

We're going to need a lot more information that you just gave us. A listing of the code would be particularly helpful, as would the exact gcc command line you're using.

The command line is "gcc sunil1.c". I precede it with rm a.out to ensure a fresh a.out each time.

The program is a simple addition program in C.

#include <stdio.h>
int main()
{
int a,b;
a=10;
b=a+78;
printf("%d",b);
}



gcc does not give any compilation errors.

Quite frustrating why even this is not working.

3. gcc results in a.out containing gibberish.

a.out is compiled, executable machine code, it should appear as gibberish. To run it from the command line, navigate to the directory it's in and type

./a.out

Or maybe I'm misunderstanding?

EDIT: Forgot to mention, if you want it named something other than a.out, use the -o option:

gcc sunil1.c -o myapp

then run with

./myapp

or to run it in a new Terminal window on OS X:

open myapp
