That looks like RSB has provided a suitable path.

What is the gdb configure command line the RSB uses?

Does the following help?

On MacOS (darwin) I gave up on the library checks and assume if the header is
present the Python install is OK.

After the build fails there should be a config.log file under `build` ...

 find build -name config.log

Does it provide any insight into why the configure failed?

I do not use rtems-central or follow it in detail.

That looks fine. Did you install python3?

Catalina should be fine. I installed Big Sur yesterday and was going to test it
today. I suspect it will only have python3 support.

Unrelated, does Catalina support APFS?
