Date: Wed, 1 Feb 2006 18:20:33 -0800 From: Eric Wing 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
