[Mesa3d-users] Glut and windows/cygwin API

[Nils <int...@gm...>]

I'm trying to compile FlightGear (flightgear.org) from CVS sources which 
requires pbib, which in turn wants GL and glut.  When I compiled the 
MesaLib 4.0.3 sources plib was still missing glut, which I found came 
from the MesaDemos 4.0.3  Once it was installed, however, plib 
compilation gave teh following errors:

...and many more like it...

I tried moving the GL/glut.h out of the way, but then definitions were 
missing.

I'm wondering what the correct way to get this support is for Cygwin.  I 
have the X headers installed (but not XFree86 base etc.).  How do I get 
Mesa to recognize that it needs to use the windows API for calls like 
this and does not have to provide them itself?

Any pointers welcome; I'm not sure which code (mesa or plib) needs to 
work differently under windows to make compilation successful.  I'm 
running the latest cygwin under win XP.

THanks,
Nils.
