good. you could try './setup.py install' once you know the module
compiled correctly.

no, that's very strange. fvec is defined in (lib/)aubio/__init__.py as
an alias to a numpy vector. it looks aubio/_aubio.pyd is empty, or not
loading. try erasing the python/gen and python/build directories, and
recompiling the module.

what makes you think it doesn't load?

on a side note, it is not very convenient to install the binary file in
more than one place. i guess you could just copy it once to
c:\windows\dll or some similar path.

best, Paul
