Universal binaries problem?
I spend a lot of time these days on universal binaries stuff and general Mac OS X OpenOffice.org
work. Thus I'm building with gcc-3.3 and gcc-4.0.1 and mix various setups on one machine. Today,
I forgot to
back to gcc 4.0.1 and tried to build universal binaries with
gcc-3.3. This was the result:
cc -isysroot /Developer/SDKs/MacOSX10.4u.sdk \
-arch i386 -arch ppc -c -o ex.o ex.c
cc: cannot specify -o with -c or -S and multiple compilations
First I was surprised what I have done wrong and then I realized I forgot to
4.0.1. This works with gcc-4.0.1 without problems.
This brought interesting question that I'm still not able to answer.
My goal is to have universal binary form of OpenOffice.org that will (in the future) work on both
PPC and Intel based Macintoshes on both Panther (PPC) and Tiger (PPC and Intel). This means I have
to use gcc-3.3 for PowerPC platform and gcc-4 for Intel platform. Xcode has the settings for this
described in the
. But how to achieve this on command line. Is it possible at all without
Can you help with this problem?
