I'd guess that you're seeing "undefined reference" when you use ldd on the
so, and that's expected. That's the wrong way to test the object, though.
Instead, install that module and import it from a python3 shell. Do you get
We have to compile/build the module before we can import it from a
python3 shell. The problem is how to compile the modules without pass
"-lpython3.9" or "-lpython3.9d" to the linker (/usr/bin/ld).
Just FWIW, "-z defs" linker flag (typically "-Wl,-z,defs" in build logs
where invoked through compiler) is one potential cause for getting
errors for this.
Ran into that myself with rpm's python module - I had it in my build
settings from whatever long forgotten experiment and suddenly started
failing when Python 3.9 changed the linkage expectations (via pkg-config)
