Hello, I have no reason be belive that the Open GL code for lesson 1 is wrong, and i know it must be my complier doing something somewhere. I have solved the original problem with VS C++ 2005 by installing the Platform SDK so i can create Win32 applications. However i cannot build the tutorial and get a whole string of errors. If anyone could possibly help, it would be much appreciated. Mac The build errors i have pasted below: ------ Build started: Project: lesson1, Configuration: Debug Win32 ------ Compiling... Lesson1.cpp Compiling manifest to resources... Linking...

Your not linking with the correct libraries.

EDIT: Try linking with OpenGL32.lib and GLu32.lib

Cheers people, massive help...!!

Thanks

I have a couple questions and problems cause I use VS C++ 2005 Express. How do I add his Project Template to it so I can use it. Also when I open his project files that you can download (The .exe runs fine) when I try to Debug it, I get a error saying No such file named "windows.h" or something along those lines. Little help.

I'm not sure about the Template since I don't use them, but the windows.h problem means you need to download and install the Platform SDK. Complete instructions can be found here.
