Build error: package failed: `tlsf_cpp` when using Python 3.10

Here's the output after running paru -S ros2-galactic:

This is with Python 3.10. Is my Python version too new?

[zjeffer]

I fixed the issue by symlinking Python 3.9 instead of 3.10 like this:

sudo ln -sf /usr/bin/python3.9 /usr/bin/python3

When installing ros2-galactic, I came across some other errors that indicated missing packages. Simply installing these packages with Python3.9's pip fixed the installation.

As Arch Linux now uses Python 3.10 by default, a better fix would be to make it work with that version.

Thanks for reporting the issue. It's reproducible.

It's an strange one because you have solved it by changing python version (but from the logs it seems to be a C++ error)... How did you figure out the fact that the error is related to python version? (I'm asking this because it would be a starting point for me to find the cause of the issue and hopefully fix it)...

A friend of mine who installed the same package today uses Python 3.9, and not 3.10. He didn't run into the issue.

I'm getting the same issue with identical output despite setting my global python version to 3.9.0 and 3.9.10 (tried both) using pyenv. Any ideas?

[m2-farzan]

I've modified the package to use an upstream fix. Waiting for the test: https://github.com/m2-farzan/ros2-galactic-PKGBUILD/runs/5324847685?check_suite_focus=true

[zjeffer]

The new package builds without the tlsf_cpp errors on Python 3.10 (but still only 0.02MiB like in #20 ).

I guess I should wait until the test completes successfully before closing this issue?

After retrying with the new package on Python 3.10.2 it successfully got past the tlsf_cpp errors, but it failed with a very similar issue while building pendulum_control. Is there a similar fix for that one?

Here's some output from the error:

I can confirm this problem. I am also running python 3.10.2.

Pushed a similar fix for pendulum_control. Waiting for the test: https://github.com/m2-farzan/ros2-galactic-PKGBUILD/runs/5332494593?check_suite_focus=true

[m2-farzan]

The tests are passing!

Thanks everybody for reporting the issues. Don't forget to star the repo if you like :)
