Missing package: bchess

[magv]

Package name: bchess Link to PyPI page: https://pypi.org/project/bchess Link to piwheels page: https://www.piwheels.org/project/bchess Version: all Python version: all I am the maintainer: Yes More information:

Hi, all. On the piwheels project page all builds for bchess are listed as failing; on the other hand I can pip3 install --user bchess without any problems on RPi 4 (Raspbian GNU/Linux 10) with Python 3.7 and PIP 21.1.1 (it does take a while, which is why it would be great if piwheels had a prebuilt version). Is it possible to check the build logs and figure out why is it failing?

I actually suspect one possible reason: bchess is using pyproject.toml which is only supported in PIP >=20.1; maybe you are using an old version on your build machines? Other than this, I'm not sure what the problem might be.

Here's the output from the latest version on cp37m:

Thanks a lot, I see what's wrong now: the sdist archive still tries to download stuff during build (i.e. lzero-common), and you probably have that blocked (which makes sense). I'll try to fix it.
