Original Post
I tried to follow the tutorial here: http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=MacOSX
But I get the error "Undefined symbols: _DrawGLScene _InitGL _ResizeGLScene"
It seems this is a fairly common problem (judging from a quick google), but I have yet to find a solution.
I also tried just downloading the project builder file for the first lesson, but it used several separate classes and changed a lot, and as I am just getting started with OpenGL, I was hoping to start with the very simplest possible program.
