JACK development files for Pipewire

Questions
#23

Hello @dscheiba
FYI the fix to find JACK development files from Pipewire has been merged into develop and will also be included in 3.13.0 when released, so this shouldn’t be a problem soon. (Of course it still applies if you want to build 3.12, unfortunately).

Thats great news to hear, thanks for the info :slight_smile: Looking forward to 3.13!

#25

So this definitely looks like it’s about having the right package installed. I’ve run apt-cache search pipewire to look for things to try and I’ve installed the likeliest looking candidates (many of them were already installed):

  • pipewire-jack
  • pipewire-audio-client-libraries
  • pipewire-alsa
  • libspa-0.2-jack
  • libpipewire-0.3-common
  • libpipewire-0.3-dev
  • libpipewire-0.3-modules
  • pipewire-bin

And still no good I’m afraid. The missing piece is a mystery.

#26

Uhm, sorry for my mistake. I thought this is for Fedora (where pipewire has been used for a while), and I provided the package name for Fedora, not Ubuntu, my bad.

pipewire-jack should definitely be installed for this to work.
Looking at this thread again, and at Ubuntu – Details of source package pipewire in kinetic, I’d try installing libjack-jackd2-dev. I hope it won’t pull the full jack2 in.

#27

… no need to apologise, this thread can serve to help people installing SC with Pipewire on various distros.

libjack-jackd2-dev does not pull in anything else, and I’ve just installed SC! Thank you to everyone that helped!

The server doesn’t start :laughing: but I think that’s for another thread.

#28

You don’t need to have a jackd2/jackdmp process running for pipewire to be working. There’s no need to manually start it. On fedora, it’s already started as a user service.

#29

I meant the SC server won’t start, not the JACK server.

#30

Could I have a look at the dockerfile ? Usually I do a -DCMAKE_BUILD_TYPE=Release just in case there’s an optimisation that makes everything run faster, since it doesn’t need debug symbols in there if it’s for performances only.

#31

Here you go :slight_smile: Right now I don’t give so much about optimization but instead more on verbosity, but maybe there are ways to make it run a bit faster?

#32

Eventually shouldn’t the compiled files be synced to the host? Also shouldn’t the docker container be the same OS version as the host?
