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 3.2 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.

Reporting bugs

Bugs are reported to our issue tracker. Please always include the name and version of the OS where the bug occurs and the version of GLFW used. If you have cloned it, include the commit ID used.

If it's a build issue, please also include the build log and the name and version of your development environment.

If it's a context creation issue, please also include the make and model of your graphics card and the version of your driver.

This will help both us and other people experiencing the same bug.

Dependencies

GLFW itself needs only the headers and libraries for your window system. It does not need the headers for any context creation API (WGL, GLX, EGL, NSGL) or client API (OpenGL, OpenGL ES) to enable support for them.

GLFW bundles a number of dependencies in the deps/ directory. These are only used by the tests and examples and are not required to build the library.

• getopt_port for examples with command-line options
• TinyCThread for threaded examples
• An OpenGL 3.2 core loader generated by glad for examples using modern OpenGL
• linmath.h for linear algebra in examples

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, join us on GitHub or IRC.
