error: invalid use of incomplete type 'PyFrameObject' {aka 'struct _frame'}

[hobbes1069]

You're right, it confused me because of the reference to coin, I took a look at the Coin4 package in Fedora and it doesn't need Python, but I had forgotten about python-pviy.

Thanks!

Whoops, got my lines crossed. The error output is from my Fedora 35 desktop which is still on Python 3.10 so that part is OK, but what is the error about?

[adrianinsaval]

From here I gather that fedora 35 uses pivy 0.6.5: http://fedora.mirror.constant.com/fedor ... x86_64.rpm
If I'm not mistaken pivy 0.6.5 has many issues with python 3.10, can you upgrade to 0.6.7? or where the fixes backported in Fedora?

[hobbes1069]

Fedora 35 and 36 is on 0.6.6, but I can upgrade them to 0.6.7.

[hobbes1069]

I updated python-pivy for Fedora 35 and 36 and am just waiting until the update hits testing again so I can try it out.

[hobbes1069]

I can confirm up pivy updated to 0.6.7 the errors are gone.

Thanks!

[hobbes1069]

As far the the original error, it looks like the two commits for Python 3.11 compatibility did not make it into the 0.20.1 release?

Thanks,
Richard

@wmayer should these be backported?

[wmayer]

If it's needed there then it should also be backported.
