Re: openGL link errors


I read that thread, but it doesn't really apply here. All of the functions I'm
calling are already setup as 'extern void APIENTRY'.

When I comment out the LINK_OPTS macro in my Makefile, I get the exact same
results, so it looks like it can't find the libraries (they're in /lib) or it
doesn't understand how to read them.

I'm trying to compile a simple openGL application under cygwin.
I have the latest version of everything (as of July 14) from the yggdrasil.com 
mirror site. I followed the instructions for linking in the openGL README, but
I'm still getting errors like:
main.o(.text+0x31):main.c: undefined reference to `glColor3f@12'
I get about 20 of these from various gl* and glut* functions.

Here is the important part of the Makefile:

INCLUDE=-I/usr/local/include
LINK_OPTS=-lglut32 -lglu32 -lopengl32

gluthello: main.o
        $(CC) $(LINK_OPTS) -o gluthello main.o

main.o: main.c
        $(CC) $(INCLUDE) -c main.c
