Delocate/auditwheel, but for Windows?`

[njs (Nathaniel J. Smith)]

You do need tricky object code rewriting (the windows loader has the exact same funny glitch that the glibc loader does, that necessitates rewriting library names to avoid isolation between wheels), but that code exists. Just no one has packaged it up into a convenient tool. I think adding support to auditwheel itself would be nice, to avoid making the packaging zoo even more confusing.

See:

Need auditwheel-like utility for other platforms

Title says it all. On Windows for example, your wheel can succeed loading locally even though some dependent DLLs are not bundled, because those wheels exist on your local system. Typical example is zlib.dll, which can be found on many Windows setups but not all of them.

Packaging DLLs on Windows

Continuing the discussion from Drawing a line to the scope of Python packaging: That’s news to me. Do you know of any documentation or simple example package demonstrating how to do that on Windows? For example, something like https://github.com/pypa/python-manylinux-demo (which shows how to use auditwheel) but for Windows would be great. CC @pf_moore
