View Full Version : undefined reference to gl everything
Okay I'm working on my very first "hello world" OGL program and I keep getting compile errors:
>undefined reference to `glClear'
>undefined reference to `glutCreateWindow'
I've included GL/glut.h; what's my problem?
Make sure you link to opengl32.lib and glut32.lib.
Sorry, I should have said, I'm on a FreeBSD machine.
Am I looking for something like
$>gcc hello.c -lGL
How do I check if I have the required files?
Okay, I've found the librarys. They where hiding in the X11R6's lib folder.
But which one do I need to include?

Here's my Makefile:
CCOPS = -c -g -Wall
LINKS = -lglut -lMesaGLU -lMesaGL -lm -lX11 -lXext -lXmu
LDPATH = -L/usr/lib -L/usr/X11R6/lib
INCS = -I. -I/usr/include
OBJS = main.o
g++ $(CCOPS) $(INCS) $<
g++ $(OBJS) $(INCS) $(LDPATH) $(LINKS) -o $@
rm -f main *.o core
