Re: [Matplotlib-users] matplotlib._path failed on windows build for Python 2.6

[Lorenzo Di G. <lor...@gm...>]

Well, that's exactly the problem: I just can't load some DLLs!

>>> import matplotlib._path

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import matplotlib._path
ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.
>>> import matplotlib._delaunay
>>> import matplotlib._image

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    import matplotlib._image
ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.
I have run python -vv, it tries also ..._path but does not load it, so I
think it might be a linking problem.
I've noticed that _delaunay.cpp has a "PyMODINIT_FUNC init_delaunay(void)"
while _path.cpp has just a "void init_path(void)".

Best Regards,
Lorenzo
