Hi, following the discussion on using ctypes in scipy, the main problem seems the inability to build a usable dll usable by ctypes using distutils. Numpy ticket 213 tackles the issue; as I need it personnally, I am willing to work on the feature, but I would need a bit some advices on numpy.distutils: - First, is anyone working on the SharedLibrary right now ? - how to add a new argument to numpy.distutils.setup ? The way I see it, but I don't understand the whole distutils arch yet so I may be wrong, would be to add one argument to the setup function, like shared_libraries, which would contains a list of objects representing the libraries (sources, name, etc...), and which would be build by a special builder. But right now, I don't know how the whole calling sequence work such as my own builder is called for the items in a given argument of setup. cheers, David
