## 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:
|

## Authors
|
|
|
|
GLEW is currently maintained by [Nigel Stewart](https://github.com/nigels-com)
|
|
with bug fixes, new OpenGL extension support and new releases.
|
|
|
|
GLEW was developed by [Milan Ikits](http://www.cs.utah.edu/~ikits/)
|
|
and [Marcelo Magallon](http://wwwvis.informatik.uni-stuttgart.de/~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.
