GLFW

Build status Build status

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.

Version 3.2 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 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 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.

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.
