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.
