[aubio-user] Using aubio 0.4.0 from python (windows)

[Paul Brossier]

Hi all!

back online after a few days on the road. great to see some activity on
the list.

I will have very little access to the network for the next two weeks, so
please accept apologies if I reply to emails with some delay.

Excellent. test-delnull.exe is supposed to crash.

Great, which version of python do you use? how did you convince it to
use gcc?

these are not crashes, but errors are produced by aubio. peakpicker and
scale are not in the python modules any more, these tests should be removed.

try running python run_all_tests -v

you need to recompile aubio with libsndfile, and optionnaly libav,
installed.

happy new year to all!
