Build status Build status Coverity Scan

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 natively supports Windows, macOS and Linux and other Unix-like systems. Experimental implementations for the Wayland protocol and the Mir display server are available but not yet officially supported.

GLFW is licensed under the zlib/libpng license.

The latest stable release is version 3.2.1.

See the downloads 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 with source and binary archives. The version history lists all user-visible changes for every release.

This is a development branch for version 3.3, which is not yet described. Pre-release documentation is available here.

The master branch is the stable integration branch and should always compile and run on all supported platforms, although details of newly added features may change until they have been included in a release. New features and many bug fixes live in other branches until they are stable enough to merge.

If you are new to GLFW, you may find the 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

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 available for all compilers supported on that platform.

See the compilation guide for more information about how to compile GLFW.

Using GLFW

See the documentation for tutorials, guides and the API reference.

Contributing to GLFW

See the contribution guide for more information.

System requirements

GLFW supports Windows XP and later and macOS 10.7 and later. Linux and other Unix-like systems running the X Window System are supported even without a desktop environment or modern extensions, although some features require a running window or clipboard manager. The OSMesa backend requires Mesa 6.3.

See the compatibility guide 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.

The Vulkan example additionally requires the Vulkan SDK to be installed, or it will not be included in the build. On macOS you need to set the path to the MoltenVK SDK manually as it has no standard location.

The documentation is generated with Doxygen. If CMake does not find Doxygen, the documentation will not be generated when you build.

Reporting bugs

Bugs are reported to our issue tracker. Please check the contribution guide for information on what to include when reporting a bug.
