GLFW

Introduction

GLFW is a free, 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.

The current stable release is version 3.2. 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.

This is version 3.2.1, which is not yet described.

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

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 check the Contribution guide for information on what to include when reporting a 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 rendering API (OpenGL, OpenGL ES, Vulkan) to enable support for them.

The examples and test programs depend on a number of tiny libraries. These are located in the deps/ directory.

• 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
• Vulkan headers 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. If CMake does not find Doxygen, the documentation will not be generated.
