numpy isn't the issue. The main Windows Python distribution requires Visual Studio 2003 for building extensions. One can do it with mingw, though, with care. > 2.

They all have tradeoffs. It might be easiest for you to actually just write your C functions into a DLL without referencing numpy or Python at all and call those functions using ctypes. That avoids needing a specific compiler and is a pretty handy tool to learn. If you do want to write an extension, I think I might suggest starting with writing one by hand. It helps with the other techniques to know what's going on underneath. -- 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 [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
