Mac OSX: Compiling SDL_mixer with Universal SDL Library

Torsten_Giebl · April 28, 2006, 10:08pm

Hello !

I just compiled the Universal SDL lib on my system with
the fatbuild script. Then i compiled the other Helper Libs.
with this Universal SDL lib. _net, _rtf, _ttf, _image. Only SDL_mixer
gave me the following error :

I know that this makes not much sense as the other libs
are not fatbuild ready now. But other people may also try this.

Is the problem that SDL was built with gcc 3.3 and SDL_mixer was built with gcc 4.0?

See ya!

I just compiled the Universal SDL lib on my system with
the fatbuild script. Then i compiled the other Helper Libs.
with this Universal SDL lib. _net, _rtf, _ttf, _image. Only SDL_mixer
gave me the following error :

ld: Undefined symbols:
___gcc_qmul
/usr/bin/libtool: internal link edit command failed

I created a gcc wrapper script (attached) which generates fat binaries
for all the other SDL_* libraries hosted at libsdl.org, unfortunately,
this trick doesn’t work with SDL_mixer, because it has subdirectories
and libtool directly extracts the objects out of the fat archives.

You can build SDL_mixer with compatible flags like this:
./configure
CC=“gcc-3.3 -arch ppc”
CPPFLAGS="-DMAC_OS_X_VERSION_MIN_REQUIRED=1020
-nostdinc
-F/Developer/SDKs/MacOSX10.2.8.sdk/System/Library/Frameworks
-I/Developer/SDKs/MacOSX10.2.8.sdk/usr/include/gcc/darwin/3.3

-F/Developer/SDKs/MacOSX10.2.8.sdk/System/Library/Frameworks
-Wl,-syslibroot,/Developer/SDKs/MacOSX10.2.8.sdk"

See ya!

gave me the following error :

Okay, this should be fixed in subversion, just update and then do:
./configure CC=“sh gcc-fat.sh”
