Does anyone have an idea why my laptop keeps freezing when I invoke
simple uses of OpenGLs accumulation buffer function, for example the
attached file (from "the Red book")?
Compiled as follows,
gcc -Wall -O3 dof.c -lglut -L/usr/X11R6/lib -lGLU -lGL -lXmu -lXi
-lXext -lX11 -lm -o dof
I do not get any core dumps or logs because it freezes so hard and fast.
Any suggestions would be great.
Thanks,
LDB
