[Numpy-discussion] Compiling for free on Windows32

Wed Apr 15 13:22:01 EDT 2009

So what is the official way to compile Numpy 1.3.0 for Python 2.4.x? If Visual Studio 2003 will not compile it and nothing else is intended to work, then surely nothing will work? That cannot be right.

PS. Perhaps there is another way to do it... compiling for me is just a means to an end. We are users of Numpy not developers of Numpy. What I want most of all to just be able to pick up a .egg file for Numpy & Scipy pre-built for Win32 by somebody else. Even better if it were an official or quasi-official distribution of the product. Does anybody know if I can just download and use Numpy + Scipy in pre-compiled in egg form?

Thanks

Borland -> don't even try them, they are not worth it.
Intel -> you may try, but I don't know if numpy or scipy was compiled with them. As there is a C compiler, as well as a C++ and a Fortran one, you may try.

David compiles with mingw, you should give it a try (although compiling them yourself will lead to worse performance, as David provides atlas with numpy and scipy).
