[CSC 315] Working on GL Code on Cobra under Windows 7/8.1

[Andrew J. Pounds]

Alrighty -- I am fed up trying to get Linux installed on computers that 
have Windows 8 installed.   For those of you that want to work on your 
code outside of the computer science building, but haven't been 
successful getting Linux installed, here is your workaround.

1. Install MobaXTerm  (http://mobaxterm.mobatek.net/).  It will allow 
XWindow to flow to your PC

2. Open up a session to cobra.cs.mercer.edu in MobaXterm

3. Compile your code with the regular settings (-lGL -lGLU -lglut)

4. Run it and look for the GL window to open with your displayed graphics.

Now, some of you are going to get and error from glut about not being 
able to open a window.   If you get this then type the
command

export LIBGL_ALWAYS_INDIRECT=1

before you execute the code.  You should only have to do this once per 
session.   This is not something you want to do in the labs as you want 
the full power of the direct rending engine -- but it should enable you 
to work on your Windows 8 systems without too much performance degradation.
