librbs.so not found (Pulpissimo)

[Roogadget]

My team and I have moved back to the version from the pulp-training because we cannot get the newer tools to work.

Now we are faced with another issue.

When we go into the pulpissimo/sim and "make run"

There is an error 1 because it cannot find the librbs.so file.

What is this file? it is missing from the tb/remote_bitbang directory.

We are on Ubuntu 22.
