    This has come up before but bears repeating. The tutorial was unfortunately written for msvc++ and #includes one-non-standard, ms specific header that's actually not required for the examples anyway (#include "stdafx.h"). It also uses, again unnecessarily, a #pragma directive(#pragma comment(linker, "/subsystem:windows"). Just remove them and I think you should be okay. If not, post again but please provide either a link to the tutorial in question or post the problematic code.

    The OpenGL libs aren't "already included" with Dev-C++, at least I don't think they are; you'll have to download them. There's probably a DevPak for OpenGL.

    No, opengl libs have been supplied with dev-cpp since at least v4.01(mingw 295.x) - ie. years before the current version.

    You only need to link with the required opengl libraries: project menu --> project options, select 'parameters' tab and add the following to the 'linker' field:
    Code:
    -lopengl32
    -lglu32
    -lglut
    -lglaux
    in the project options dialog.

    edit:

    Actually, you'll also need to remove all those #pragma statements. In fact, the opening few lines should look like this:
    Code:
    #define WIN32_LEAN_AND_MEAN
    
    //#pragma comment(lib, "opengl32.lib")
    //#pragma comment(lib, "glu32.lib")
    //#pragma comment(lib, "glaux.lib")
    //#pragma comment(linker, "/subsystem:windows")
    
    //#include "stdafx.h"
    #include <windows.h>                                    // standard Windows app include
    //#include <winuser.h>          // Windows constants
    #include <gl/gl.h>                                              // standard OpenGL include
    #include <gl/glu.h>                                             // OpenGL utilties
    #include <glut.h>                                       // OpenGL utilties
    
    #define WND_CLASS_NAME  "OpenGL Window Class"
