I think I just have GLUT. My /usr/include/GL/glut.h file just points to
freeglut_std.h. There's no other glut.h file on my system.

I have both, but I don't think there's much chance of a mixup there, the
pointers aren't even the same size, and I get no warnings about wrong
sized pointers in compiling any of this.

[j...@black PDL]$ gcc -o bitfont -march=opteron -O3 -fPIC -I/usr/include
-I/usr/X11R6/include -I/usr/local/include -L/usr/lib64 -
L/usr/X11R6/lib64 -L/usr/local/lib64 -lglut -lGL -lglut -lGLU -lXext -
lXmu -lXi -lICE -lX11 -lm bitfont.c
[j...@black PDL]$ ./bitfont
Seems to work just fine.
Then I went in and added the other 4 fonts that I see defined in the
POGL pogl_const.h file:
8 by 13
Helvetica 10
Helvetica 12
Helvetica 18
Then I recompiled, and it worked fine on all of the fonts as well.
Do you have a POGL version of that program to try?
