This tutorial shows you how to compile a C/C++ program in Mac OS using Eclipse. Remember that GNU is the linux-based compiler and hence if we want to use it for Mac OS, we have to have certain executable(s) to be running in Mac OS.

Development Package

You can get the same development package as the one we promote for ARM processors.

  • Get the Development Package and unzip in an absolute directory
    SourceForge SJSU Development Package
    It is important to NOT unzip at your desktop
    The unzipped path should not have spaces


Open Eclipse and Create New Project

1. Open Eclipse.
   Always open the MINGW batch file
   since it sets up environment variables for you.

Open MINGW bat file in your development package directory

2. Create a new C/C++ Project

  • Go to File --> New --> C++ Project
  • Name your project anything you want, preferably without spaces.
  • Choose Executable --> Hello World C++ Project and MINGW GCC
  • Then click Finish
Create New Eclipse C++ Project

Create New Eclipse C++ Project

3. Write your source code
   Copy the simple source code on the right.

#include <stdio.h>

int main(void)
{
    /* Without this, printf() will not work */
    setvbuf(stdout, 0, _IONBF, 0);
    setvbuf(stdin,  0, _IONBF, 0);

    /* Write rest of your code here */
    printf("Hello World\n");
    return 0;
}

4. Run your program

  • First, build your program by going to Project --> Build Project
  • Now, go to Run --> Run
  • The output will appear in the Console tab below.
Run your project


4. Optional : Debug your program

  • To perform debugging or run your code one line of code at a time, you can perform debugging.
  • Now, go to Run --> Debug
  • Your program will now "pause" at the main() function.
  • You can now use the Run menu to execute one line at a time.
  • Other hints :
    Double clicking on the code window sets a breakpoint.
    You must press the red stop button to stop your program.
