cadabra2 2.4.2 build issue: type_caster_base.h error: member access into incomplete type 'PyFrameObject'

[Schamschula]

When building cadabra2 2.4.2 under MacPorts (I'm the package maintainer) I get the following error:

:info:build In file included from /opt/local/var/macports/build/_Users_marius_Development_MacPorts_ports_math_cadabra2/cadabra2/work/cadabra2-2.4.2/client_server/Server.cc:3:

I didn't see this problem with version 2.4.0.2.

I think this has more to do with you using Python 3.11 than with Cadabra itself (I don't think there are any changes in Cadabra which could cause this). I will update the bundled pybind11 library to see if that makes the problem go away. Will ping you here again when that's done.

[kpeeters]

I have pushed a commit which updates pybind11 to their current HEAD. Can you try building with that (it's tagged as 2.4.2.1) and let me know?

I get an error applying the patch to

What happens if you do a clean checkout/clone?

[Schamschula]

I get a clean build!
