I'm wondering if there is any new development in the OpenGL libraries within 
cygwin. The package in the distribution says it is version 1.1, but the 
current OpenGL release, from Sept 2004, is v2.0. The last pre-2.0 version 
was 1.5.

The last comment I found in the archives was from Andre Bleau in Feb 2003. 
He laid out a development plan but I can't find any changes after that time. 
Does anyone know if anything has happened lately? I'd like to use some of 
the 2.0 capabilities, but it doesn't look like I can get there with cygwin.


Thanks for any info,
Thom

Thom,

There never was an implementation of native OpenGL for Cygwin. All there is 
is a way for Cygwin programs to access the underlying implementation of 
OpenGL for Windows, and that implementation is stuck at version 1.1. Unless 
Bill Gates changes his mind about OpenGL, it will never be upgraded.

There are ways to use the features of more recent OpenGL implementations 
provided with graphic card drivers through the use of extensions. That's a 
problem that all OpenGL developpers on the Windows platform have to face, 
not just the ones programming for Cygwin. If you want more info about how to 
do that,  please look at the programming forums at http://www.opengl.org/ .

The "development plan" you mentionned was about GLUT, a library often used 
by OpenGL programs, not about OpenGL itself.
