# Makefile - Don Yang (uguu.org)
#
# Compiles, links, and runs on at least one linux box.  Your mileage
# may vary.
#
# If you can't get it to build, try using MesaGL:
#  http://www.mesa3d.org/
#
# And set libs+includes below to where the mesa libraries are built.
#
# Some systems don't like how some macros are defined before the
# headers are included.  On those systems, you may get things to
# compile by forcing some header files to be processed first:
#
#  gcc -O3 -include GL/glut.h koyomi.c -lGL -lGLU -lglut -o koyomi
#
# (GL/glut.h is usually the only one that fails)
