Hi -- I have a problem that is similar to one discussed in a thread from a year ago, http://mail.python.org/pipermail/distutils-sig/2004-September/ 004160.html, but that thread doesn't quite have a resolution in the archives. I'd like to use distutils to build a bunch of python modules that all link to the same shared library. The shared library is all C++code. On Linux, without distutils, I can build the libraries like this:g++ -o libBase.so -shared base.C # builds the common shared library g++ -o _mymodule.so -shared mymodule.C -lBase # builds a python module # linking to the shared lib. g++ -o _othermodule.so -shared othermodule.C -lBase # and so on _mymodule.so and _othermodule.so can be imported by Python, and share a single copy of the code in libBase.so. On the Mac I can get the same effect with this: g++ -dynamiclib base.C -o libBase.dylib g++ -o _mymodule.so mymodule.C -lBase -bundle -undefined dynamic_lookup -flat_namespace g++ -o _othermodule.so othermodule.C -lBase -bundle -undefined dynamic_lookup -flat_namespace
Don't use -flat_namespace. Search the pythonmac SIG archives if you want a more elaborate rant :-).
Is it possible to create libBase portably with distutils? It's possible to do it on Linux by subclassing build_ext.build_ext and explicitly using self.compiler.compile() and self.compiler.link_shared_lib() to build the shared library before calling build_ext.build_ext.build_extensions(). But the same thing on Mac OS X only creates libBase.so, whereas I need it to create libBase.dylib.
I don't know if this is possible, although I'd guess it is not.
If it matters, I'm using OS X 10.4.2 and gcc 3.3, with Python 2.3.5.
