## Introduction
|
|
|
|
|
|
2016-08-09 01:34:56 +02:00
|
|
|
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.
|
2013-02-04 10:46:02 +01:00
|
|
|
|
2019-04-16 01:36:49 +02:00
|
|
|
GLFW natively supports Windows, macOS and Linux and other Unix-like systems. On
|
2019-08-28 21:28:23 +02:00
|
|
|
Linux both X11 and Wayland are supported.

GLFW is licensed under the [zlib/libpng

You can [download](https://www.glfw.org/download.html) the latest stable release
|
2019-04-16 01:36:49 +02:00
|
|
|
as source or Windows binaries, or fetch the `latest` branch from GitHub. Each
|
|
|
|
|
release starting with 3.0 also has a corresponding [annotated
|
2016-08-17 16:48:22 +02:00
|
|
|
tag](https://github.com/glfw/glfw/releases) with source and binary archives.
|

|
|
|
|
2021-06-09 22:43:27 +02:00
|
|
|
The [documentation](https://www.glfw.org/docs/latest/) is available online and is
|
2019-04-16 01:36:49 +02:00
|
|
|
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
|
2021-06-09 22:43:27 +02:00
|
|
|
history](https://www.glfw.org/changelog.html).
|
2017-01-29 20:10:53 +01:00
|
|
|
|
|
|
|
|
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.

[tutorial](https://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If
|
2017-07-12 00:21:17 +02:00

you have used GLFW 2 in the past, there is a [transition

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
|
2013-10-21 22:23:15 +02:00
|
|
|
|
2019-04-16 01:36:49 +02:00
|
|
|
GLFW itself requires only the headers and libraries for your OS and window
|
|
|
|
|
system. It does not need the headers for any context creation API (WGL, GLX,
|
|
|
|
|
EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable
|
|
|
|
|
support for them.
|
2016-07-14 18:32:30 +02:00
|
|
|
|
2016-07-14 18:29:39 +02:00
|
|
|
GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
|
2016-10-20 00:50:54 +02:00
|
|
|
MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
|
2016-07-14 18:29:39 +02:00
|
|
|
and Clang. It will likely compile in other environments as well, but this is
|
|
|
|
|
not regularly tested.
|
2013-02-04 10:46:02 +01:00
|
|
|
|
2021-06-09 22:43:27 +02:00
|
|
|
There are [pre-compiled Windows binaries](https://www.glfw.org/download.html)
|
2017-07-12 00:21:17 +02:00
|
|
|
available for all supported compilers.

## System requirements

|
|

2019-01-03 19:32:45 +01:00

GLFW supports Windows XP and later and macOS 10.8 and later. Linux and other
|
2017-01-29 20:10:53 +01:00
|
|
|
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.

## Dependencies
|
|
|
|
|
|
2016-08-09 01:34:56 +02:00
|
|
|
GLFW itself depends only on the headers and libraries for your window system.
|
|
|
|
|
|
2017-06-09 16:32:24 +02:00
|
|
|
The (experimental) Wayland backend also depends on the `extra-cmake-modules`
|
2019-12-10 20:10:12 +01:00
|
|
|
package, which is used to generate Wayland protocol headers.
|
2017-06-09 16:32:24 +02:00
|
|
|
|
2016-02-08 16:23:44 +01:00
|
|
|
The examples and test programs depend on a number of tiny libraries. These are
|
|
|
|
|
located in the `deps/` directory.
