Compiling Instructions

For Linux -
1. The command line is
  gcc foobar.c -lglut -lGLU -lGL -o foobar
2. Sometimes it may require the -lX11 -lXi and -lXmu libraries which will require you to add -L/usr/X11R6/lib to the command line too in addtion to the libraries.
For Windows -
1. Add the GL libraries to your linker path.
2. Make sure you have the GL DLL's in your system directory.
3. Build your project and it should work alright.

Checkout the Makefile in colorcube.tgz for further clarifications.

Some Tips

OpenGL was meant to be platform independent - try to keep your code that way !!!
Try and use GLUT wherever possible - it makes your code more portable.
If you want to program specifically for X or for Windows - use GLX for X and WGL for Windows - GLUT does this for you so you are anyway better off sticking to what I said earlier.
If you want to get fancy about userinput devices, networked stuff and sound explore the host of opensource libraries which are available to do the stuff. A very good thing to use here is SDL (Simple Directmedia Layer) - it is also supposed to be platform independent.
Don't be disheartened if you happen to see a totally black window (nothing drawn) first time you run your GL code - it happens to everyone !!
