Because I can't let it go ...

• Look at the Makefile
  • -lGL means to link against the openGL library
  • ls /usr/lib64/libGL*
• Everything else should be fine.
• Look at square.cpp
  • Includes should make sense.
  • #pragma - compiler specific directives
    • This is entirely ignored by the GCC compiler.
  • In main
    • argc, argv
    • glutInit() - initializes the glut library
    • glutInitContext* - configure the machine for a specific version of openGL.
    • glutInitDisplay* - What type of graphics will we support
    • glutInitWindow* - where do we want the window and what size
    • glutCreateWindow - actually create a version of the window
    • GlutDisplayFunc, GlutReshapeFunc, GlutKeyboardFunc - set callbacks
    • glewInit() - initialize glew
    • setup () - local function wich sets up the graphics environment
    • glutMainLoop()
