Right. In this case, "-shared" needs to be "-dynamiclib" on OS X, so this should go into the tool. > For Mac OS X, you may be bitten by -undefined dynamic_lookup.

That's the basic idea. Rigorously, it's probably a bit more involved when you start considering two-level namespaces and framework. One thing to note is that this option is only valid for GNU compilers. Linking with ifort, I need to use -Wl,-undefined,dynamic_lookup . -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
