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 produced a log: http://pastey.net/74970
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?
Thanks and cheers,

Hello Brian,
Sorry I'm not able to help you, though I'd like to warn you that
several Free projects have been bitten by universal binaries because
they haven't been careful enough to test the binary produced on both
Intel Macs and PPC Macs. Compiling with "-arch i386 -arch ppc" and
then running make check gives the false impression that the binary
produced work, because people easily forget it works only on the
$host. That's why they often build the the Intel and PPC versions
separately (and thus test them separately) and then `lipo' them
together.
Cheers,
