In my simple OpenGL program I get the following error about exit redefinition:

1>c:\program files\microsoft visual studio 8\vc\include\stdlib.h(406) : error C2381: 'exit' : redefinition; __declspec(noreturn) differs 1>        c:\program files\microsoft visual studio 8\vc\platformsdk\include\gl\glut.h(146) : see declaration of 'exit'

I’m using Nate Robins’ GLUT for Win32 and get this error with Visual Studio 2005 or Visual C++ 2005 (Express Edition). What is the cause of this error and how do I fix it?

  1. Cause:

    The stdlib.h which ships with the recent versions of Visual Studio has a different (and conflicting) definition of the exit() function. It clashes with the definition in glut.h.

    Solution:

    Override the definition in glut.h with that in stdlib.h. Place the stdlib.h line above the glut.h line in your code.

    #include <stdlib.h> #include <GL/glut.h>
