[Python-Dev] Unable to build regex module against Python 3.5 32-bit

[Steve Dower]

The builds I am responsible for include it because someone reported an issue and was persistent and helpful enough that I fixed it for them.

That said, until MinGW agrees on a stable branch/version/fork, there seems to be a good chance that the shipped lib won't work for some people. If this is what's happened here, I see it as a good enough reason to stop shipping the lib and to add instructions on generating it instead (the gendef/dlltool dance).

Cheers,
Steve

Hmm, I just checked and it seems that only Python 3.5 ships
libpythonXY.a by default - 3.4 and earlier (at least on my machine)
don't have it. Presumably you generated it yourself for the previous
versions?

So I wonder if this is a difference between how you built your version
previously and how the shipped version is now built. The code to build
the shipped version is in Tools\msi\dev\dev.wixproj. It runs

    gendef - "$(BuildPath)$(PyDllName).dll" >
"$(IntermediateOutputPath)mingwlib.def"
    dlltool --dllname $(PyDllName).dll --def
"$(IntermediateOutputPath)mingwlib.def" --output-lib
"$(BuildPath)lib$(PyDllName).a" -m $(_GenDefPlatform)

which looks OK to me (_GenDefPlatform is i386 on 32-bit and
i386:x86-64 on 64-bit).

Paul
