I installed the latest ubuntu and the problem with requiring the library goes away.
I also found my problem. I renamed my base package when I was refactoring, so I was “using” a package name that didn’t exist in the precompiled package anymore in my example C++ build. No idea how I would ever have known this from the output error messages. I would have hoped that I would have received a different error maybe.
Silly mistake. I should have done a blanket search and replace refactoring on the project and not just the julia code.
