And, if you copy the libgfortran.a file to somewhere else, say ~/staticlibs/,
you can force the linker to use it instead of the .dylib such that your users
don't need to install gfortran.
$ export LDFLAGS="-undefined dynamic_lookup -bundle -arch i386 -arch ppc
-Wl,-search_paths_first"
$ python setup.py config_fc --fcompiler=gnu95 --arch="-arch i386 -arch ppc"
build_ext -L ~/staticlibs/ build
...
$ file build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so
build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so: Mach-O universal binary
with 2 architectures
build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so (for architecture i386):
Mach-O bundle i386
build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so (for architecture ppc):
Mach-O bundle ppc
$ otool -L build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so
build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so:
/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate
(compatibility version 1.0.0, current version 4.0.0)
/usr/local/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current
version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
88.3.7)
The pointer to /usr/local/lib/libgcc_s.1.dylib is innocuous. That's just the
first place it will look for that library at runtime. There's one in /usr/lib
that appears to be picked up and used just fine.
Problem solved. Finally.
