I don't know how mingw64 is supposed to work, but going by the 32-bit mingw, you might have to create a libpython27.a first.

That did the trick! Apparently we can't link to MSVC dlls http://sourceforge.net/apps/trac/mingw-w64/wiki/Answer%2064%20bit%20MSVC-generated%20x64%20.lib Creating a *.a fixes it. Thanks.

If somebody would contribute a patch for msi.py that builds the file, and instructs me what tools I need installed, I'd be willing to include this in future releases (also for 2.7).

I don't know how to patch the installer, but here are the commands for someone who does. You need gendef and dlltool, which should come with the standard mingw64 installation. From python27.dll: $ gendef python27.dll $ dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libpython27.a --input-def python27.def

For peoples who interesting in supporting building Python with mingw-w64 compiler I can get some links. More than a year ago we start providing our own builds of Python 2.7+3.3 builded with mingw-w64 compiler. I'm developer of MSYS2 project - modern fork of Cygwin with MSYS functionality + pacman package manager (ported from Arch Linux). You can easily build your own Python with mingw-w64 using our patches that include patches from Roumen Petrov (rpetrov) and our own. Python-2.7.6 patches: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python2 Python-3.3.3 patches: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3 Also you can get prebuilded python and other mingw-w64 packages using MSYS2 with pacman. Regards, Alexey.

Python 2.7 is no longer supported.
