[prog] OpenGL/Mesa/Glut

[Sue Stones]

Well further searches on Google have produced that I need to set CFLAGS thus

"CFLAGS=-I/usr/X11R6/Include"


"/usr/X11R6/Include" is the directory, what is the -I before that?

Also, is anyone able to explain CFLAGS?  It is some sort of enviroment 
variable, used by the C compiler I think.  How do I get the compiler to use 
it?

What is the best way to set CFLAGS.
