    Do you have the function body in a separate source file or in the header also? Post up your header file and lets have a look. When you get a linker error like that it is saying it can't find the body to the function you're trying to call.

    I figured it out thanks

    I was also wondering could I just make a program that initializes say a library like OPENGL and then create a header file for that and only have to call 1 function in my main program code to initialize OPENGL. Well I am sure it could be done but I was wondering how I would go abouts this.

    May be an undefined reference to WinMain on line 16? LOL. Post the code.
