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 3.1.2 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
linmath.h for linear algebra in examples
