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,
Libtool is well aware of universal archives. ar x does not work
with universal archives, so libtool uses lipo(1) to extract the
objects for each architecture and put them back together again.
This is because Mac OS X has no equivalent for GNU ld's --whole-
archive flag. What is the problem, I do not see a failure in your log.
Ah, I see, the -arch flags are being stripped. Update to a newer
version of GNU libtool (1.5.22 should do), or put the -arch flags in
the CC and CXX environment vars (e.g. ./configure CC='gcc -arch ppc -
arch i386').
