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.
Note that a number of source files have been added or renamed in 3.1, which may require you to update any custom build files you have.
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 bundles a number of dependencies in the deps/
directory.
- Khronos extension headers for API extension symbols used by GLFW
- 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

- [Win32] Bugfix: Maximized hidden windows were restored by
glfwShowWindow
- [Win32] Bugfix: Context re-creation was not triggered by sRGB hint
- [Win32] Bugfix: Full screen windows were incorrectly sized and placed on some systems
- [Win32] Bugfix: Gamma ramp functions acted on entire desktop instead of the specified monitor

withXRRGetScreenResourcesCurrent
for monitor property retrieval - [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 uncaughtBadWindow
error - [X11] Bugfix: No check was made for the presence of GLX 1.3 when
GLX_SGIX_fbconfig
was unavailable - [X11] Bugfix: The message type of ICCCM protocol events was not checked

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
.
