## 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. On
|
|
Linux both Wayland and X11 are supported.
|
|
|
|
GLFW is licensed under the [zlib/libpng
|
|
license](https://www.glfw.org/license.html).
|
|
|
|
You can [download](https://www.glfw.org/download.html) the latest stable release
|
|
as source or Windows binaries. Each release starting with 3.0 also has
|
|
a corresponding [annotated tag](https://github.com/glfw/glfw/releases) with
|
|
source and binary archives.
|
|
|
|
The [documentation](https://www.glfw.org/docs/latest/) is available online and is
|
|
included in all source and binary archives. See the [release
|
|
notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
|
|
deprecations in the latest release. For more details see the [version
|
|
history](https://www.glfw.org/changelog.html).
|
|
|
|
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](https://github.com/glfw/glfw/branches/all) until
|
|
they are stable enough to merge.
|
|
|
|
If you are new to GLFW, you may find the
|
|
[tutorial](https://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](https://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
|
|
3 API.
|
|
|
|
GLFW exists because of the contributions of [many people](CONTRIBUTORS.md)
|
|
around the world, whether by reporting bugs, providing community support, adding
|
|
features, reviewing or testing code, debugging, proofreading docs, suggesting
|
|
features or fixing bugs.
|
|
|
|
|
|
## Compiling GLFW
|
|
|
|
GLFW is written primarily in C99, with parts of macOS support being written in
|
|
Objective-C. GLFW itself requires only the headers and libraries for your OS
|
|
and window system. It does not need any additional headers for context creation
|
|
APIs (WGL, GLX, EGL, NSGL, OSMesa) or rendering APIs (OpenGL, OpenGL ES, Vulkan)
|
|
to enable support for them.
|
|
|
|
GLFW supports compilation on Windows with Visual C++ (2013 and later) 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 [pre-compiled binaries](https://www.glfw.org/download.html) available
|
|
for all supported compilers on Windows and macOS.
|
|
|
|
See the [compilation guide](https://www.glfw.org/docs/latest/compile.html) for
|
|
more information about how to compile GLFW yourself.
|
|
|
|
|
|
## Using GLFW
|
|
|
|
See the [documentation](https://www.glfw.org/docs/latest/) for tutorials, guides
|
|
and the API reference.
|
|
|
|
|
|
## Contributing to GLFW
|
|
|
|
See the [contribution
|
|
guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
|
|
more information.
|
|
|
|
|
|
## System requirements
|
|
|
|
GLFW supports Windows 7 and later and macOS 10.11 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](https://www.glfw.org/docs/latest/compat.html)
|
|
in the documentation for more information.
|
|
|
|
|
|
## Dependencies
|
|
|
|
GLFW itself needs only CMake 3.16 or later and the headers and libraries for your
|
|
OS and window system.
|
|
|
|
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
|
|
- [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
|
|
functions
|
|
- [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
|
|
examples
|
|
- [Nuklear](https://github.com/Immediate-Mode-UI/Nuklear) for test and example UI
|
|
- [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
|
|
|
|
The documentation is generated with [Doxygen](https://doxygen.org/) if CMake can
|
|
find that tool.
|
|
|
|
|
|
