Hi @karlderletzte, I don’t know anything about pipewire (or development for it), but I thought I would post this in case it is helpful. What version of the C++ compiler are you using?
I ran into problems building Rack that can load most plugins. It turns out the problem was I was using g++ older than version 12.2.0, which caused more than half of my installed plugins to fail to load. I know this is not the same as your problem, but… maybe it’s useful?
I ended up building g++ 12.2.0 from source. Then I used that to build Rack. Now I have a fully functional VCV Rack built from source.
Also, have you looked in your log.txt for any clues you can post here?
