Using GCC natively in Linux


Setting up a GCC Environment

Unix-based Operating Systems (Linux)

If you run Unix or Linux, you should have GCC already installed on your machine with most, if not all appropriate libraries. Open up a terminal then copy and paste the following code into a file called hello.c and save it in your home directory:

#include <stdio.h>
int main ()
    printf ("Hello, World! Get ready for the GP2X!!\n");
    return 0;

In your terminal, type

gcc hello.c -O2 -Wall -s -o hello

and hit enter. This will compile the file hello.c into and executable named hello with the optimisations O2 (Optimisation Level 2) and s (Strip the final executable, to make it smaller). To run the program, type


and hit enter. The program should print Hello, World! Get ready for the GP2X!! and then exit. Congratulations! You're on your way to being a developer!
