Error building wheel for rustpython_ast (pyo3)

[pawamoy]

I cloned the repository, entered the ast-pyo3 directory, and ran pyproject-build:

Any hint on how to fix that 🙂?

As to why I'm trying to build it, well, I'd like to try it in a project of mine to see how well it performs and how much work it would need to use it instead of Python's ast.

Quick question by the way: it builds an Abstract Syntax Tree and not a Concrete Syntax Tree right?

Hi, welcome to ast pyo3 support. I usually built it with maturin, like maturin develop for dev version.
I am not very familiar with this ecosystem. Is pyo3 projects usually expected to be built with pyproject-build?

[pawamoy]

Thanks for your help!

Is pyo3 projects usually expected to be built with pyproject-build?

pyproject-build is a build frontend for Python projects. It reads pyproject.toml and uses the specified build-system metadata to build sdists and wheels for Python projects. In your case, pyproject.toml specifies maturin>=0.15,<0.16 as the build-backend, so pyproject-build uses maturin to build this project.

After your comment, I tried building with maturin develop directly, and it worked. I thought removing the cap to 0.16 in the build-system metadata would fix it (latest is 1.5.1), but no. pyproject-build apparently runs the following command:

maturin pep517 build-wheel -i /tmp/build-env-3os4z0xe/bin/python --compatibility off

(/tmp/build-env-3os4z0xe/bin/python is a temporary virtualenv)

I'm not familiar with maturin so I don't know how to make maturin pep517 build-wheel work like maturin develop.

[pawamoy]

Weirdly enough if I use this command with maturin 1.5.1 directly, it works...

This crate now placed in https://github.com/RustPython/rustpython-ast-pyo3
This issue seems to be happened with parsers default bigint feature malachite. I fixed this issue in the new repository.

[pawamoy]

Thanks @youknowone, I'll try the new repository and report back 🙂

[pawamoy]

Yay that worked! Thanks a lot!
