This one is really annoying me. All of a sudden, I'm having linking problems with glu.h, OpenGL Utility. I'm using Dev-C++ and I'm creating an OpenGL project, Dev-C++ already had OpenGL installed with it, so I don't know why it's not linking. It used to. But now it's not. I get this trying to use gluPerspective():
[Linker error] undefined reference to `gluPerspective@32'
Any idea why it may have stopped working and how to fix it?
