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 Status Gitter Download

Downloads

Current release is 2.1.0. (Change Log)

Sources available as ZIP or TGZ.

Windows binaries for 32-bit and 64-bit.

Recent snapshots

Snapshots may contain new features, bug-fixes or new OpenGL extensions ahead of tested, official releases.

Build

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. For most end-users of GLEW the official releases are the best choice, with first class support.

Linux and Mac

Using GNU Make

Install build tools

Debian/Ubuntu/Mint: $ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev libosmesa-dev

RedHat/CentOS/Fedora: $ sudo yum install libXmu-devel libXi-devel libGL-devel

Build
$ make
$ sudo make install
$ make clean

Targets: all, glew.lib (sub-targets: glew.lib.shared, glew.lib.static), glew.bin, clean, install, uninstall

Variables: SYSTEM=linux-clang, GLEW_DEST=/usr/local, STRIP=

Note: may need to make auto folder

Using cmake

CMake 2.8.12 or higher is required.

Install build tools

Debian/Ubuntu/Mint: $ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev cmake git

RedHat/CentOS/Fedora: $ sudo yum install libXmu-devel libXi-devel libGL-devel cmake git

Build
$ cd build
$ cmake ./cmake 
$ make -j4
Target Description
glew Build the glew shared library.
glew_s Build the glew static library.
glewinfo Build the glewinfo executable (requires BUILD_UTILS to be ON).
visualinfo Build the visualinfo executable (requires BUILD_UTILS to be ON).
install Install all enabled targets into CMAKE_INSTALL_PREFIX.
clean Clean up build artifacts.
all Build all enabled targets (default target).
Variables Description
BUILD_UTILS Build the glewinfo and visualinfo executables.
GLEW_REGAL Build in Regal mode.
GLEW_OSMESA Build in off-screen Mesa mode.
BUILD_FRAMEWORK Build as MacOSX Framework. Setting CMAKE_INSTALL_PREFIX to /Library/Frameworks is recommended.

Windows

Alternative toolchain: SYSTEM=msys, SYSTEM=msys-win32, SYSTEM=msys-win64

glewinfo

glewinfo is a command-line tool useful for inspecting the capabilities of an OpenGL implementation and GLEW support for that. Please include glewinfo.txt with bug reports, as appropriate.

Code Generation

A Unix or Mac environment is needed 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.

GLEW is originally derived from the EXTGL project by Lev Povalahev. The source code is licensed under the Modified BSD License, the Mesa 3-D License (MIT) and the Khronos License (MIT).

The automatic code generation scripts are released under the GNU GPL.
