Problem building 32-bit and 64-bit binaries on Mac OS X 10.6.4

[Elvis Dowson]

Hi,
        I'm unable to build libtool as binary that includes both 32-bit and 
64-bit intel architecture on Mac OS X 10.6.4 using gcc-4.0.1, and get the 
following error:

gcc-4.0: -E, -S, -save-temps and -M options are not allowed with multiple -arch 
flags

The errors are the same for libtool-2.2.10.tar.gz package and the latest 
version of libtool from the git repository.

$ git clone git://git.savannah.gnu.org/libtool.git
$ cd libtool
$ ./bootstrap
$ ./configure CC='/usr/bin/gcc-4.0' CPP='/usr/bin/cpp-4.0' 
CXX='/usr/bin/g++-4.0' CXXCPP='/usr/bin/cpp-4.0' CFLAGS='-arch i386 -arch 
x86_64' CPPFLAGS='-arch i386 -arch x86_64' CXXFLAGS='-arch i386 -arch x86_64' 
LDFLAGS='-arch i386 -arch x86_64'

How can I build a binary that works for both 32-bit and 64-bit architectures? 
Has anyone done this successfully before?


If I try to use gcc-4.2.1, which is the default compiler, it doesn't even get 
past the configure stage, so that's why I've been trying to use gc-4.0.1

./configure CC='/usr/bin/gcc-4.2' CPP='/usr/bin/cpp-4.2' CXX='/usr/bin/g++-4.2' 
CXXCPP='/usr/bin/cpp-4.2' CFLAGS='-arch i386 -arch x86_64' CPPFLAGS='-arch i386 
-arch x86_64' CXXFLAGS='-arch i386 -arch x86_64' LDFLAGS='-arch i386 -arch 
x86_64'
