## 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](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.

This is version 3.2.1, 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

See the [Compiling GLFW](http://www.glfw.org/docs/latest/compile.html) guide in
the GLFW documentation.


## Using GLFW

See the
[Building programs that use GLFW](http://www.glfw.org/docs/latest/build.html)
guide in the GLFW documentation.


## Compile-time requirements

GLFW supports compilation on Visual C++ 2010 and later, MinGW and MinGW-w64,
Clang on OS X and GCC and Clang on Linux and other Unix-like systems.  It will
likely compile in other environments as well, but this is not regularly tested.

See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
more information.


## Run-time 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)
for more information.


## 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.


## 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](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
 - [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.


## Changelog

 - Bugfix: Single compilation unit builds failed due to naming conflicts (#783)
 - Bugfix: The range checks for `glfwSetCursorPos` used the wrong minimum (#773)
 - [Win32] Bugfix: `glfwSetClipboardString` created an unnecessary intermediate
                   copy of the string
 - [Win32] Bugfix: Examples failed to build on Visual C++ 2010 due to C99 in
                   `linmath.h` (#785)
 - [Win32] Bugfix: The first shown window ignored the `GLFW_MAXIMIZED` hint
                   when the process was provided a `STARTUPINFO` (#780)
 - [GLX] Bugfix: Dynamically loaded entry points were not verified
 - [EGL] Bugfix: Dynamically loaded entry points were not verified
