## Code Generation
If you wish to build GLEW from scratch (update the extension data from
the net or add your own extension information), you need a Unix
environment (including wget, perl, and GNU make). The extension data
is regenerated from the top level source directory with:
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
make extensions
An alternative to generating the GLEW sources from scratch is to
download a pre-generated (unsupported) snapshot:
