Hey I've just about finished the second chapter of Luke Bensteads book "Beginning OpenGL Game Programming 2nd edition" and when it comes down to compiling the code I've typed along with his example code, I keep getting a LNK2019 Error

I've looked around the internets for the solution to this problem but to no avail. Alls I could find was setting your sub-system in the Linker settings to Windows. I've already had it set to windows and switching it to anything else but windows will tack on an extra unresolved external error. Anyone have any clues?

You probably need to link a .lib file to your project or add in the .cpp and .h file that has GLWindow code in it...
