The latest development version of SDL is available via Mercurial. Mercurial allows you to get up-to-the-minute fixes and enhancements; as a developer works on a source tree, you can use “hg” to mirror that source tree instead of waiting for an official release. Please look at the Mercurial website ( http://mercurial.selenic.com/ ) for more information on using hg, where you can also download software for Mac OS X, Windows, and Unix systems.
hg clone http://hg.libsdl.org/SDL
If you are building SDL with an IDE, you will need to copy the file include/SDL_config.h.default to include/SDL_config.h before building.
If you are building SDL via configure, you will need to run autogen.sh before running configure.
There is a web interface to the subversion repository at: http://hg.libsdl.org/SDL/
There is an RSS feed available at that URL, for those that want to track commits in real time.
