Linking Issues on MacOS X 10.6.5

[Mario Donick]

... because I accidently removed all the contents of my /usr/local folder, I had to reinstall fpc, lazarus and SDL. Because the framework version did not work anymore when I tried to use the compiler call above (it did not find the SDL library although libSDLmain.a was again in /usr/local/lib), I removed the SDL framework and instead installed the source version of SDL. ./configure, make, make install worked without problems and now all SDL libs are in /usr/local/lib again. Only for SDL image, I still use the framework version.

I changed the compiler call to

fpc -Mobjfpc -ve -k-lSDL -k-lSDLmain -k-framework -kSDL_image -k-framework -kCocoa -Fl/usr/X11/lib fprl.pp


This gives me the following output:

Linking fprl

ld: warning: in /usr/local/lib//libSDLmain.a, file was built for unsupported file format which is not the architecture being linked (i386)

"_SDL_SetVideoMode", referenced from:
_P$FPRL_SETOPTIONS in fprl.o

and so on.

Esp. the first three lines are disturbing me.

What can I do now? I was so happy that everything worked, but obviously I did not understand how I got SDL to work on my system, so I can't explain the process to end users of the game as well.

Please please help ... (I read all the topics related to SDL on MacOS in this forum, I also read the section on freepascal.org).


Edit: Just in case it is a problem with PowerPC vs. i386, I tried to use the option to build a universal binary, as stated in the MacOS X readme in the SDL source folder. There it says I could call a script named fatbuild.sh. Well, I tried, but this script seems to have errors, or not to work anymore on Leopard.
