From your web site, I got the impression that SciPy for Windows has been built with Numeric-21.0, but this information looks dated. So, I have tried several versions (CVS included), but somehow the SciPy installer refused to overwrite the necessary modules (maybe because

Hoping to do an easy install for a student, I tried to install SciPy on Windows and to port some of my NumPy extensions to Windows. (I am a Linux user, with very little Windows experience). The SciPy windows installer policy of overwriting a few modules, got me into trouble. This has the side effect that the Numerical header files (and C-API numbers) are out of sync with the binary modules. Consequently, my home cooked extensions started to return NumPy arrays of Complex instead of Float :-) they were newer, or because my registry database is broken -- I am running Windows 98 with Win4Lin under Linux). IMHO, it is much more friendly to include a full NumPy (even if it is not the latest), instead of only a few binary modules. You are locking authors of NumPy based extension modules out of the 'market' ( I have written a Qt/Qwt based plotting package, see http://gerard.vermeulen.free.fr ). MicroSoft has been sued for a similar policy :-) Regards -- Gerard Vermeulen PS: your recipy for rebuilding SciPy on Windows looks pretty old. Did anybody try MinGW-2.O.O? And is MSYS-1.0.7 sufficient to build ATLAS? PPS: I am not rich enough to sue you.
