I am trying to make a universal binary out of our software on OSX. The general strategy is to configure with LDFLAGS/CXXFLAGS="-arch i386 -arch ppc". This seems to work for our convenience libraries, which become fat, but when it comes time to make one of our distribution libraries, libtemt, libtool recognizes the convenience libs are fat and "unfats" them!
I assume I am doing something wrong, although I know that libtool is unaware of mac universal binaries. Does anyone have suggestions for getting my libs to be i386/ppc, without resorting to building on the actual hardware for each and lipo'ing them together?
