# GLEW - The OpenGL Extension Wrangler Library
|
||||
|
||||
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

## Build
|
||||
|
||||
From a downloaded tarball or zip archive:
|
||||
It is highly recommended to build from a tgz or zip release snapshot.
|
||||
The code generation workflow is a complex brew of gnu make, perl and python, that works best on Linux or Mac.
|
||||
The code generation is known to work on Windows using [MSYS2](https://www.msys2.org/).
|
||||
For most end-users of GLEW the official releases are the best choice, with first class support.
|
||||
|
||||
### Linux and Mac
|
||||
|
||||
#### Using GNU Make
|
||||
|
||||
GNU make is the primary build system for GLEW, historically.
|
||||
It includes targets for building the sources and headers, for maintenance purposes.

## Contributions
|
||||
|
||||
GLEW welcomes community contributions. Typically these are co-ordinated
|
||||
via [Issues](https://github.com/nigels-com/glew/issues) or
|
||||
[Pull Requests](https://github.com/nigels-com/glew/pulls) in the
|

GitHub web interface.
|

Be sure to mention platform and compiler toolchain details when filing
|

a bug report. The output of `glewinfo` can be quite useful for discussion
|

also.
|

|
||||
Generally GLEW is usually released once a year, around the time of the Siggraph
|
||||
computer graphics conference. If you're not using the current release
|

version of GLEW, be sure to check if the issue or bug is fixed there.
