----------------------------------------------------------------------
PLEASE READ THIS MAIL CAREFULLY. IT CONTAINS IMPORTANT INFORMATION FOR
INSTALLING THE OPENGL PACKAGE. A COPY OF THE README FILE CAN BE FOUND
AT THE END OF THIS MESSAGE.
----------------------------------------------------------------------

To update your installation, click on the "Install Cygwin now" link on
the http://sources.redhat.com/cygwin web page.  This downloads setup.exe
to your system.

Run setup and answer all of the questions.  PLEASE, PLEASE, PLEASE
choose a mirror site for your download.  The 'sources.redhat.com' site
is badly overloaded.  The mirrors below have the latest version of this
package:

ftp://ftp.sunsite.utk.edu (US)
ftp://gd.tuwien.ac.at (Austria)
ftp://ftp.freesoftware.com (US)

Note that if this is the first time that you've run the new GUI version
of setup, it will currently download the whole cygwin net release again.
After this point it will only download and install what is needed.

If you have questions or comments, please send them to the Cygwin
mailing list at:  cygwin@sources.redhat.com .  I would appreciate if you
would use this mailing list rather than emailing me directly. This
includes ideas and comments about the setup utility or Cygwin general.

If you want to make a point or ask a question the Cygwin mailing list is
the appropriate place.

GLUT, GLU and OpenGL header files; GLUI header file and library
---------------------------------------------------------------

Package opengl-1.1.0-3 updated 20/11/2000


*** WARNING ***
---------------

This package does _not_ contain a complete set of files for building Open GL
-based programs. It contains only the missing pieces in the Cygwin environment
to build programs calling functions from opengl32.dll and glu32.dll provided
by Microsoft in Windows NT 4.0 and Windows 2000. I don't know about Windows
95/98.

There is also an include file and a DLL for building GLUT-based programs
and include files and static libraries for GLUI-based programs.



Installation
------------

Use the setup utility from www.cygwin.com.



Linking of code calling OpenGL, GLU, GLUT
-----------------------------------------

Add -lglut32 -lglu32 -lopengl32 to your link command.



Linking of code calling OpenGL, GLU, GLUT, and GLUI
---------------------------------------------------

Add -lglui -lglut32 -lglu32 -lopengl32 to your link
command.



Linking of code calling OpenGL, GLU, GLUT, GLUI, and GLUIX
----------------------------------------------------------

Add -lgluix -lglui -lglut32 -lglu32 -lopengl32 to your link command.

libglui.a and libgluix.a are static libraries.

libglut32.a, libglu32.a and libopengl32.a interface with Windows
NT/2000. I don't know about Windows 95/98. They are part of Cygwin 1.1.x.

What has changed since opengl-1.1.0-2
-------------------------------------

GLUI has been updated to version 2.02.

GLUIX version 1.0 has been added to the package.

The package now installs in /usr instead of /usr/local. If you had a 
previous version of the opengl package installed, you may delete the 
following files:
	/READMEopengl-1.1.0-2.txt
	/usr/local/include/GL/glut.h
	/usr/local/bin/glut32.dll
	/usr/local/doc/opengl-1.1.0/glui_manual_v2_beta.pdf
	/usr/local/doc/opengl-1.1.0/glut-3.spec.pdf
	/usr/local/include/GL/gl.h
	/usr/local/include/GL/glu.h
	/usr/local/include/glui.h
	/usr/local/lib/libglui.a


What has changed since opengl-1.2.1-1
-------------------------------------

The previous package name errounously suggested that it was for Open GL 
1.2.1 while it is in fact for the Open GL 1.1.0 DLL provided by Microsoft.

The declaration of glGetString in gl.h has been corrected to include the 
APIENTRY qualifier.
