Hi, I’m trying to learn SuperCollider,
I compiled it from source on Fedora 40.
Problem i’m having is that when i do ctrl+b to start the backend server it closes. Here is whats sent to the terminal:

SCDoc: Indexing help-files...
SCDoc: Indexed 1375 documents in 0.49 seconds
Booting server 'localhost' on address 127.0.0.1:57110.

I’m not familiar with Linux audio so i don’t know whats going on.

Does your system have Pipewire? If so, try:

Server.program = "pw-jack scsynth";

(… and try again to boot the server.)

Note, I’m not certain this will work immediately. I haven’t set up pipewire on my system. But the idea behind pipewire is to make it easier to do exactly what you’re doing, so I’d suggest to try that first.

Otherwise you’re in the purgatory of getting PulseAudio and JACK to cooperate. This isn’t so difficult if you’ve done it before; first time may require some patience. If pipewire does the trick, may be better to sidestep that whole issue if possible.
