Yeh, I have the same problem, and I have a FULL install (all packages). ld can't link any glut calls, so there's a Cygwin setup problem. Cygwin Opengl package comes with gl, glu, glut headers, glut32.dll, and libglui.a libgluix.a. There's no libglut.a. I think that OpenGL is required by XWindow, so libGL.a and libGLU.a exist in X11R6 lib path. glxgears works, so gl works, but glut doesn't.
yes, the listing at http://www.cygwin.com/packages/opengl/opengl-1.1.0-6 confirms this.. no libglut.a typical... maybe this is because the win32 and unix sources for glut are integrated into the same source tree now and maybe the glut make process decides to make only a DLL if you make it on windows, (even under cygwin). If so, that is pretty annoying... still, the opengl-1.1.0-6-src ie the SOURCE package, DOES contain all the glut sources, so why not get this source package and try compiling it, and try to find out why the rotten thing doesnt produce a libglut.a if you cant compile a libglut.a from that source package, then maybe try downloading the original sources for the glut, from opengl.org and see if that will compile under cygwin. If you do use the real openGL glut, when you do the install, it will not install the headers, just the libglut.a So you'll have to install the headers yourself. Just go into the package's include directory and copy the glut.h into /usr/local/include/GL/ or some such location. Besides that, I had no problems compiling my glut. it was simple, and it beats me why cygwin and some other distribution makers make obtaining a working glut such an ordeal. Surely someone on this list has got HOpenGL working on cygwin.. if so.. maybe they could let the list know where they got their glut. John
