I'm not sure what the library would be as I have never used open/gl, but it maybe that you need to append this -lgl on the end of $ gcc -Wall -o test test.c -L/usr/local/lib/GL -L/usr/local/lib/GLU -L/usr/local/lib/GLUT > /usr/local/lib contains the following files: > libGL.a libGLU.a libOSMesa.a libglut.a > libGL.la libGLU.la libOSMesa.la libglut.la > > What am I missing? > > If this falls out of the scope of this mailing list (due to MESA not being > an official cygwin package), I apologize. > > I've been googling all day, looking for the answer, but I haven't found it > yet. Hope someone here can help me out. As you said here is not really the place to ask this. The better alternative to the cygwin ml would be perhaps the gcc-users list. Take a look at , there should be a relavent list there. Also take a look at the README/INSTALL that came with MESA which might tell you exactly what libs you need to link with ;-) > Regards, Mikael Regards, Elfyn McBratney elfyn AT exposure DOT org DOT uk www.exposure.org.uk -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
