GLFW

Introduction

GLFW is a free, Open Source, multi-platform library for OpenGL and OpenGL ES application development. It provides a simple, platform-independent API for creating windows and contexts, reading input, handling events, etc.

Version 3.1 is not yet described.

If you are new to GLFW, you may find the introductory tutorial for GLFW 3 useful. If you have used GLFW 2 in the past, there is a transition guide for moving to the GLFW 3 API.

Compiling GLFW

See the Compiling GLFW guide in the GLFW documentation.

Using GLFW

See the Building programs that use GLFW guide in the GLFW documentation.

Dependencies

GLFW bundles a number of dependencies in the deps/ directory.

The following dependencies are needed by GLFW:

• Khronos extension headers

The following dependencies are needed by the examples and test programs:

• getopt_port for getopt
• TinyCThread for threading
• An OpenGL loader generated by glad

• [X11] Bugfix: The case of finding no usable CRTCs was not detected
• [X11] Bugfix: Detection of broken Nvidia RandR gamma support did not verify that at least one CRTC was present
• [X11] Bugfix: A stale _NET_SUPPORTING_WM_CHECK root window property would cause an uncaught BadWindow error

Contact

The official website for GLFW is glfw.org. There you can find the latest version of GLFW, as well as news, documentation and other information about the project.

If you have questions related to the use of GLFW, we have a support forum, and the IRC channel #glfw on Freenode.

If you have a bug to report, a patch to submit or a feature you'd like to request, please file it in the issue tracker on GitHub.

Finally, if you're interested in helping out with the development of GLFW or porting it to your favorite platform, we have an occasionally active developer's mailing list, or you could join us on #glfw.
