Subject: [SDL] Mac OS X Video Drivers [patch]
I've updated/added the Carbon and X11 video drivers
to the Mac OS X port of SDL 1.2 (the CVS version),
and made the Cocoa driver and runtime *optional*.
The default is still Cocoa, and the "Quartz" driver.
But you can now also use "toolbox" for Carbon, and
"x11" for running with Apple's (or other) X11 server:
export SDL_VIDEODRIVER=x11
export SDL_VIDEO_GL_DRIVER=/usr/X11R6/lib/libGL.dylib
It also checks if the frameworks are available, by a:
#include <Carbon/Carbon.h> or #import <Cocoa/Cocoa.h>
(this should make it configure on plain Darwin as well?)
Here are the new configure targets:
--enable-video-cocoa use Cocoa/Quartz video driver default=yes
--enable-video-carbon use Carbon/QuickDraw video driver default=yes
--enable-video-x11 use X11 video driver default=no
./configure --enable-video-cocoa --enable-video-carbon
--enable-video-x11 \
--x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib
The Carbon version is just an updated version of the old
SDL driver for Mac OS 9, and could probably be improved...
(but it does work, including the Carbon version of SDLmain)
If you disable cocoa, you can run with -framework Carbon only,
and the C version of SDL_main.c. And if you disable carbon too,
you can still use the X11 version which doesn't require SDLmain.
I updated the DrawSprocket version, but did not include it.
(no blitters or VRAM GWorlds etc. available on OS X anyway)
Besides for Mac OS 9, I don't think there's any use for it ?
And note that any performance on Mac OS X equals OpenGL anyway...
You can get "fair" software SDL results on captured CG displays,
but for decent frame rates you need to be using GL for rendering.
Finally, here is the patch itself:

--anders
PS. It says "video", but as usual it applies to mouse/keyboard too.

Subject: [SDL] Updated Mac patch
Updated the previous Mac patch to disable Carbon by default.
Also "fixed" the SDL.spec again, so that it builds on Darwin.
http://www.algonet.se/~afb/SDL-1.2.9-mac.patch
Also applied fine to SDL12 CVS, when I tried it.
