matplotlib/wxmpl/numpy conflict on windows xp: runtime error, C-API ?

Hi,

···

I'm trying to install a matplotlib+wxmpl app I wrote on Linux on a Windows XP machine. It crashes starting with the following error:
-----
C:\Documents and Settings\Principale\Desktop\Python\Hooke>python hooke.py
Traceback (most recent call last):
   File "hooke.py", line 12, in ?
     import wxmpl
   File "C:\Programmi\Python23\Lib\site-packages\wxmpl.py", line 26, in ?
     from matplotlib.axes import PolarAxes, _process_plot_var_args
   File "C:\PROGRA~1\Python23\Lib\site-packages\matplotlib\axes.py", line 23, in
?
     from contour import ContourSet
   File "C:\PROGRA~1\Python23\Lib\site-packages\matplotlib\contour.py", line 18,
in ?
     import _contour
   File "C:\PROGRA~1\Python23\Lib\site-packages\matplotlib\_contour.py", line 17,
  in ?
     from matplotlib._ns_cntr import *
RuntimeError: module compiled against version 90709 of C-API but this version of numpy is 1000000
-----

I installed the latest sourceforge stable (not CVS/SVN) versions of matplotlib, numpy and wxmpl as of today.

I'm quite puzzled, I guess I understand what the error is (different gcc versions?), but how can I get around it? Do I need to recompile numpy/matplotlib?

I am guessing you installed numpy1.0b1. You need to use 0.9.8.

Thanks a lot. I uninstalled 1.01b1 and installed 0.9.8 and everything workes perfectly.

Thanks again,
Massimo
