Subject: OpenGL 3.0 Context Creation
I've attached a patch which implements OpenGL 3.x context creation on
the latest SVN. I've added two options to SDL_GL_SetAttribute, these
are SDL_GL_CONTEXT_MAJOR_VERSION and SDL_GL_CONTEXT_MINOR_VERSION.
These default to 2 and 1 respectively. If the major version is less
than 3 then the current context creation method is used, otherwise the
appropriate new context creation function is called (depending on the
platform).
Sample code:
if (SDL_Init(SDL_INIT_VIDEO) != 0) {
printf("Unable to initialize SDL: %s\n", SDL_GetError());
return 1;
}
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3); //Without these 2 lines, SDL will create a GL 2.x context
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
SDL_Surface* screen = SDL_SetVideoMode( 640, 480, 16, SDL_OPENGL | SDL_FULLSCREEN );
I've implemented context creation on both Win32 and X and run basic
tests on both. This patch doesn't provide access to all the options
allowed by the new context creation (e.g. shared contexts, forward
compatible contexts) but they can be added pretty easily.

The latest development version of SDL is available via Subversion. Subversion allows you to get up-to-the-minute fixes and enhancements; as a developer works on a source tree, you can use svn to mirror that source tree instead of waiting for an official release. Please look at the Subversion website ( http://subversion.tigris.org/ ) for more information on using svn, where you can also download software for MacOS, Windows, and Unix systems. svn checkout http://svn.libsdl.org/trunk/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://www.libsdl.org/cgi/viewvc.cgi There is an RSS feed available at that URL, for those that want to track commits in real time.
