Jan Harkes added the comment:
@Carl.Kleffner: that is an interesting message but it discusses using
binutils(/mingw?) generated import libraries with the MS linker.
This bugreport was about two 64-bit objects that were accidentally included in
an otherwise 32-bit library and it has been
Carl Kleffner added the comment:
I experienced this behaviour by accident several times. Most likely this is due
to inconsistenticies in different binutils and mingw-runtime versions/patches.
See i.e. http://article.gmane.org/gmane.comp.gnu.binutils/46799
A robust solution is to exclusively
Carl Kleffner added the comment:
The most robust way to support a specific mingw-w64 distribution is to copy a
python import library generated by this specific toolchain and the provided
import library for the corresponding msvcrXX.dll runtime into the libs folder.
This has to be performed by
Benjamin Gilbert added the comment:
Is there any reason an import library generated by a particular MinGW version
shouldn't be usable by any other MinGW version?

Paul Moore added the comment:
I'm still somewhat confused as to why we're looking at this in the context of
manually building an extension. It's *certainly* true that anyone attempting to
build a Python extension by hand (as per Matthew Barnett's instructions) should
be able and willing to
Benjamin Gilbert added the comment:
Zachary: gendef is an auxiliary tool; I'm not sure a basic installation of
MinGW-w64 will have it. However, I've checked Cygwin and Fedora (my two points
of reference) and a gendef package is available in both.

@steve.dower: Yes.
For Python 35, it appears that it'll link to libpython??.a or python??.dll,
whichever it finds in the given folder, so it doesn't actually need
libpython??.a anymore. Which is nice. :-)

The Python-2.7.9 version of the Windows-x86 MSI installed version works fine
with the 32-bit mingw. In fact I rolled back to that release and built my code
successfully.
Somehow the fix for https://bugs.python.org/issue23199 must have broken the

Here's how I can build the regex module on Windows 8.1, 64-bit, using only
MinGW64.
For Python 3.5, I can link against python35.dll, but for earlier versions,
including Python 2.7, I need libpython??.a.
I have built regex module for all of the 16 supported

Given I can't generate the file any other way that will be compatible for
everyone, unless someone contributes a fix I'm going to stop shipping these
files and let people generate them using whatever tools they have.
