[Biopython-dev] [Numpy-discussion] Python extensions for Python 3.5 - useful info...

[Peter Cock]

Hi Chris,

I'd like to retire this WinXP box, but not until I have another
Windows development machine setup (perhaps a VM).
For now it is handy for building our Biopython installers
for 32-bit windows, and as a buildbot slave, but its days
are numbered.

I've not looked into how to install MSCV 14.0 but it would
not surprise me that it isn't available on Windows XP.

Biopython would benefit from one or more developers
working primarily on Windows (which is what I did when
I first started).

Peter
