Wheel-builders -- Discussion of building and distributing Python packages, esp. extension packages, as wheels


About Wheel-builders
English (USA)

Wheels let us distribute pre-built Python libraries -- which is great! Especially for libraries that are difficult to build, contain binary extensions with complicated dependencies, and/or want to support users on multiple platforms.

But actually building wheels is still something of a black art. There are all kinds of little tricks needed, that vary between different platforms, and traditionally there hasn't been one central place to go to learn about these. (For example, the MacPython wiki is great, but unless you're specifically a Mac developer then you may not even know it exists.)

This mailing list is for everyone who wants to build and distribute wheels for their packages, and for collaborating to improve the relevant tooling and documentation. Everything discussed here would also be in scope for distutils-sig or even pypa-dev, but here we have a more narrow focus on the practicalities of getting individual packages working and writing code. Newbie questions welcome!

Some example goals: (a) Improving the tooling for building standalone wheels, like "delocate" and "auditwheel". (This is the home list for those packages.) (b) Building common infrastructure for handling native library dependencies. (c) Writing documentation for package developers on how to use all this stuff (perhaps in the form of a new chapter for packaging.python.org. (d) Developing better tools for automated builds (e.g., sharing scripts for getting free CI services to build our wheels for us).

We also have a wiki.
