The latest development version of SDL is available via git. Git allows you to get up-to-the-minute fixes and enhancements; as a developer works on a source tree, you can use "git" to mirror that source tree instead of waiting for an official release. Please look at the Git website ( https://git-scm.com/ ) for more information on using git, where you can also download software for macOS, Windows, and Unix systems.
git clone https://github.com/libsdl-org/SDL
If you are building SDL via configure, you will need to run autogen.sh before running configure.
There is a web interface to the Git repository at: http://github.com/libsdl-org/SDL/
