[![Build Status](https://travis-ci.org/nigels-com/glew.svg?branch=master)](https://travis-ci.org/nigels-com/glew)

## Build

If you downloaded the tarball or zip archive from the GLEW website,
you just need to:

### Unix

* make
* sudo -s
* make install
* make clean

### Windows

use the project file in build/vc12/

## 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:

    make extensions

An alternative to generating the GLEW sources from scratch is to
download a pre-generated (unsupported) snapshot:

Travis-built sources are also available:
