Probewheel

An auditwheel-like tool for Windows binary extension modules. A work-in-progress. It currently does not re-bundle wheel files, but handles the collection and renaming/relinking of shared libraries.

Usage

• First, install probewheel dependencies by running install-deps.bat.
• Then:

python probewheel.py <path\to\binary-module.pyd>

Output

This should create a folder called _libs in the above path that will contain the pyd re-linked to a set of DLLs renamed to include a 7-digit SHA. If everything went well, you should be able to import your module after adding it to your PYTHONPATH environment variable.

Caveats

• Binaries built using mingw toolchains should have the GNU binutils strip utility run against them before running probewheel.
• Do NOT run strip against MSVC-built binaries, since this can/will corrupt them.
• This project is still experimental. I do not promise that it will work in current form, and I can't even promise to help you get it to work for your project.
• External dependencies that are not to be bundled (system-level dependencies) are currently whitelisted internally in probewheel.py, modify this as necessary for now. The whitelist may be configurable in a future version.
