[issue20785] Missing symbols in Python27.lib (Windows 64bit)

[Alexey Pavlov]

Alexey Pavlov added the comment:

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.

[issue20785] Missing symbols in Python27.lib (Windows 64bit)

Victor Lazzarini added the comment:

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

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).

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.

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.
