Code Generation
A Unix or Mac environment is neded for building GLEW from scratch to include new extensions, or customize the code generation. The extension data is regenerated from the top level source directory with:
make extensions
An alternative to generating the GLEW sources from scratch is to download a pre-generated (unsupported) snapshot:
https://sourceforge.net/projects/glew/files/glew/snapshots/
Travis-built snapshots are also available:
https://glew.s3.amazonaws.com/index.html
Authors
GLEW is currently maintained by Nigel Stewart with bug fixes, new OpenGL extension support and new releases.
GLEW was developed by Milan Ikits and Marcelo Magallon. Aaron Lefohn, Joe Kniss, and Chris Wyman were the first users and also assisted with the design and debugging process.
The acronym GLEW originates from Aaron Lefohn.
Pasi Kärkkäinen identified and fixed several problems with
GLX and SDL. Nate Robins created the wglinfo utility, to
which modifications were made by Michael Wimmer.
