Some linker errors I don't understand

[Sperry]

I have recieved some linker errors in my program:

I really do not understand these, could someone help please?

It means you're not linking to some OpenGL or GLU import library.

Thanks, so I've got these librarys:

#include <windows.h> // Header File For Windows
#include "gl\gl.h" // Header File For The OpenGL32 Library
#include "gl\glu.h" // Header File For The GLu32 Library

So what do I need to do?

[DSvMDjzh]

should be

#include "gl/gl.h"
#include "gl/glu.h" 

you need to change the slash

[Sperry]

Thanks, but that doesn't make any difference.

[DSvMDjzh]

Do you actually have the librarys? if you don't you can download them somewhere.

You need to link your project to OpenGL32.lib and glu.lib (not sure about the second one)
How to do that depends on your ide.

[Kangaroux]

#include <gl/gl.h>
#include <gl/glu.h>  

Unless you have the files locally in your project directory, you need the "<" and ">".

Also, what hamster said.

Quotes work, as well.
