[SciPy-User] Build on Win32-x86 / Intel fortran

Mon Jan 18 20:03:33 EST 2016

Indeed, I had read Steve Dower's blog post (
http://stevedower.id.au/blog/building-for-python-3-5-part-two/) before, but
I should have re-read it:
=====================Always statically link

The build options are updated to statically link the DLL if
PY_VCRUNTIME_REDIST is empty.

If you set DISTUTILS_USE_SDK but not PY_VCRUNTIME_REDIST, you will get
statically linked vcruntime140.dll. This is probably the biggest surprise
from the change.

==========================

By setting the PY_VCRUNTIME_REDIST environment variable, everything works.

Thanks everyone.
Michael
