My off hand guess is that this is a tool chain issue on certain host
systems. For example, I never got this error on our OpenSUSE machines.
I can set up a OpenSUSE virtual machine and try it. I noticed the RSB
documentation does not have a set of packages for OpenSUSE – I could
send a docs patch after a successful build. What release do you use? Do
you have a list of packages to install?
We use openSUSE Leap 15.3 and 15.4. To get the packages maybe try this:
zypper in -t pattern devel_C_C++ devel_python3
