Subject: SDL/Universal Binary updates
Hi Sam,
Attached is a big set of changes to the Xcode projects to support
Universal Binaries. I have also included .dmgs that include the
prebuilt frameworks.
Ryan, I also updated SMPEG which is also in the package.
The SDL and smpeg binaries were built against the CVS version (pulled
maybe a month ago?).
I do not have an Intel Mac to test on so I have no idea if this stuff
actually works. However, Christian Walther has been a big help in
testing 10.2.8 and 10.3.9 so I'm fairly confident we got the build
settings correct for at least PPC.
I have attempted to document the important things for producing these
Universal Binaries. Documentation is somewhat scattered through out
everything, but there is a big centralized piece of documentation in
the UniversalBinaryNotes.rtf in the SDL.dmg.
As far as Universal Binaries are concerned, the big things were:
- Build with gcc 3.3 on PPC, 4.0 on Intel.
- We couldn't get any of the MMX/SSE code to compile/link (SDL and
smpeg).
- All 3rd party dependencies had to be rebuilt as Universal
There were also a bunch of non-Universal things that have been updated:
- I converted the SDL-satellites to create .dmg's instead of .pkg
installers
- Updated all 3rd party static libraries with current versions. (I
think libpng was the most dramatic going from 1.0.? to 1.2.8 with API
breakage. I haven't found any problems so far in doing this.)
- Changed some compiler optimization settings
- Finally updated the exports list for SDL_mixer
- Tried to include a static smpeg in SDL_mixer (multiple build
variants in Xcode project now)
- Enabled Altivec in SDL (we forgot to add the flags to Xcode last time)
- More documentation
Since so many things have changed, there might be new problems
introduced. The big issue I've found so far is with SDL_mixer. As I
mentioned on the mailing list, MP3's produce an assertion failure.
And the MikMod problem reported on Bugzilla continues to persist.
There's probably a bunch of other stuff I'm forgetting. There really
were hundreds of little things I mucked with so it's hard to remember
them all.
If you have any questions, feel free to ask.
Thanks,
Eric

============================================================================== Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC ============================================================================== These instructions are for people using the Apple MPW environment: http://developer.apple.com/tools/mpw-tools/ CodeWarrior projects are available in the CWprojects directory. ============================================================================== I. Building the Simple DirectMedia Layer libraries: (This step isn't necessary if you have the SDL binary distribution) First, unpack the MPWmake.sea.hqx archive and move SDL.make into the SDL directory. Start MPW Set the current directory within MPW to the SDL toplevel directory. Build "SDL" (Type Command-B and enter "SDL" in the dialog) If everything compiles successfully, you now have the PPC libraries "SDL" and "SDLmain.o" in the 'lib' subdirectory. ============================================================================== II. Building the Simple DirectMedia Layer test programs: First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to the main SDL directory, and move the makefiles in the new test subdirectory to the SDL 'test' subdirectory. Start MPW Set the current directory within MPW to the SDL 'test' subdirectory. Build the programs that have an associated MPW makefile (file ending with .make), including "testwin", "testalpha", and "graywin". Copy the SDL library file into the test directory, and run! ============================================================================== III. Building the Simple DirectMedia Layer demo programs: Copy one of the test program Makefiles to the demo directory and modify it to match the sources in the demo. ============================================================================== IV. Enjoy! :) If you have a project you'd like me to know about, or want to ask questions, go ahead and join the SDL developer's mailing list by sending e-mail to: sdl-request@libsdl.org and put "subscribe" into the subject of the message. Or alternatively you can use the web interface: http://www.libsdl.org/mailman/listinfo/sdl ==============================================================================
