Re: [linux-audio-dev] compiling LADSPA for Mac OS X

I believe that you need to use the following CFLAGS:
-fno-common -flat_namespace -bundle -undefined suppress -lbundle1.o

I've not tried them, but a couple of people have reported sucessfully
building my plugins with the flags, you can get them automatically by doing
        ./configure --enable-darwin
before building
