[SDL] MacOSX universal SDL libs for makefile-based project

[David Bruce]

Hi,

I'm trying to build a universal MacOSX binary for my program (tuxmath) on a 
new Intel iMac running Leopard (10.5).  The program builds and installs 
properly with "./configure; make; sudo make install" and runs fine.

When I try to do the ppc crossbuild, the ppc *.o files get generated OK, but 
the linking fails (of course) because my SDL and other  needed libs are 
i386-only (I build SDL and friends on my machine using Fink).

So, I would like to get universal binary libs in place for SDL, SDL_image, 
SDL_mixer, and SDL_ttf (also gettext, but that's another story).

1. grabbing the SDL-1.2.13 dmg file and copying the framework 
into /Library/Frameworks didn't work, I assume because my program is 
makefile-based rather than using XCode.

2. Using the SDL-1.2.13 source, I tried the 'fatbuild.sh' script, which I 
think is supposed to be what I need, but it fails:

janis-lehtinens-imac:SDL-1.2.13 dbruce$ sudo sh build-scripts/fatbuild.sh

See `config.log' for more details.

fwiw, no 'config.log' is written.

3. I've also tried ./configure and make using CFLAGS="-O -g -arch i386 -arch 
ppc"  and LDFLAGS="-arch i386 -arch ppc", which fails at the linking stage 
with:

ld: warning in build/.libs/mmx_main.o, file is not of required architecture

  "_ConvertMMXpII32_16BGR565", referenced from:

(and about twenty more "_ConvertMMX*" and "_ConvertX86*" undefined symbols).


Is there any established way to get universal binary versions of the SDL libs 
onto a system for use in a makefile-based project?

Thanks,
