# GLFW [![Build status](https://travis-ci.org/glfw/glfw.svg?branch=master)](https://travis-ci.org/glfw/glfw) [![Build status](https://ci.appveyor.com/api/projects/status/0kf0ct9831i5l6sp/branch/master?svg=true)](https://ci.appveyor.com/project/elmindreda/glfw) [![Coverity Scan](https://scan.coverity.com/projects/4884/badge.svg)](https://scan.coverity.com/projects/glfw-glfw) ## Introduction GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan application development. It provides a simple, platform-independent API for creating windows, contexts and surfaces, reading input, handling events, etc. GLFW is licensed under the [zlib/libpng license](https://opensource.org/licenses/Zlib). The latest stable release is version 3.2.1. See the [downloads](http://www.glfw.org/download.html) page for details and files, or fetch the `latest` branch, which always points to the latest stable release. Each release starting with 3.0 also has a corresponding [annotated tag](https://github.com/glfw/glfw/releases) with source and binary archives. This is a development branch for version 3.3, which is _not yet described_. If you are new to GLFW, you may find the [tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If you have used GLFW 2 in the past, there is a [transition guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW 3 API. ## Compiling GLFW GLFW itself requires 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 rendering API (OpenGL, OpenGL ES, Vulkan) to enable support for them. GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC and Clang. It will likely compile in other environments as well, but this is not regularly tested. There are also [pre-compiled Windows binaries](http://www.glfw.org/download.html) available for all compilers supported on that platform. See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) in the documentation for more information. ## Using GLFW See the [building application guide](http://www.glfw.org/docs/latest/build.html) guide in the documentation for more information. ## System requirements GLFW supports Windows XP and later, OS X 10.7 Lion and later, and Linux and other Unix-like systems with the X Window System. Experimental implementations for the Wayland protocol and the Mir display server are available but not yet officially supported. See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html) in the documentation for more information. ## Dependencies GLFW itself depends only on the headers and libraries for your window system. The examples and test programs depend on a number of tiny libraries. These are located in the `deps/` directory. - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples with command-line options - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded examples - An OpenGL 3.2 core loader generated by [glad](https://github.com/Dav1dde/glad) for examples using modern OpenGL - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in examples - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk - [Vulkan headers](https://www.khronos.org/registry/vulkan/) for Vulkan tests The Vulkan example additionally requires the Vulkan SDK to be installed, or it will not be included in the build. The documentation is generated with [Doxygen](http://doxygen.org/). If CMake does not find Doxygen, the documentation will not be generated when you build. ## Reporting bugs Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues). Please check the [contribution guide](https://github.com/glfw/glfw/blob/master/.github/CONTRIBUTING.md) for information on what to include when reporting a bug. ## Changelog - Added `glfwGetKeyScancode` function that allows retrieving platform dependent scancodes for keys (#830) - Added `glfwSetWindowMaximizeCallback` and `GLFWwindowmaximizefun` for receiving window maximization events (#778) - Added headless [OSMesa](http://mesa3d.org/osmesa.html) backend (#281,#850) - Added definition of `GLAPIENTRY` to public header - Bugfix: Calling `glfwMaximizeWindow` on a full screen window was not ignored - Bugfix: `GLFW_INCLUDE_VULKAN` could not be combined with the corresponding OpenGL and OpenGL ES header macros - Bugfix: `glfwGetInstanceProcAddress` returned `NULL` for `vkGetInstanceProcAddr` when `_GLFW_VULKAN_STATIC` was enabled - [Win32] Bugfix: Undecorated windows could not be iconified by the user (#861) - [Cocoa] Added support for Vulkan window surface creation via MoltenVK (#870) - [Cocoa] Bugfix: Disabling window aspect ratio would assert (#852) - [Cocoa] Bugfix: Window creation failed to set first responder (#876,#883) - [Cocoa] Bugfix: Removed use of deprecated `CGDisplayIOServicePort` function (#165,#192,#508,#511) - [EGL] Added support for `EGL_KHR_get_all_proc_addresses` (#871) ## Contact On [glfw.org](http://www.glfw.org/) 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 [forum](http://discourse.glfw.org/), and the `#glfw` IRC channel on [Freenode](http://freenode.net/). 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](https://github.com/glfw/glfw/issues) 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 the forum, GitHub or IRC. ## Acknowledgements GLFW exists because people around the world donated their time and lent their skills. - Bobyshev Alexander - artblanc - arturo - Matt Arsenault - Keith Bauer - John Bartholomew - Niklas Behrens - Niklas Bergström - Doug Binks - blanco - Kyle Brenneman - Martin Capitanio - Chi-kwan Chan - Lambert Clara - Andrew Corrigan - Noel Cower - Jason Daly - Jarrod Davis - Olivier Delannoy - Paul R.
