making connections via rtmidi?

[UltraBlackLinux]

Hey there,
is it possible to make pipewire/jack connections via rtmidi? I've not seen a way to do so yet, but maybe the terminology has confused me.
Any hints?
Thanks!

JACK support has been working for *nix-like (incl. Linux and MacOS) systems for a long time. It used to be dependent on libpthread which is the standard multi threading library on *nix systems. Of course, the JACK support must be compiled into the software. Further instructions can be given if you tell us which build system you are using on which operating systems.

When you are using Pipewire, a special libjack must be used in order to connect to the pipewire demon. There are some pitfalls in its configuration. So you should always make sure that native JACK applications like jack-play work, bofore testing higher-level interfaces like RtMidi.

I'm on Arch Linux with pipewire, using g++.
Pipewire does have a drop-in replacement for jack so I don't think it would take anything special to use jack libraries with pipewire, but maybe I've got some wrong impressions there, you tell me.

How does your software, which libjack to use? Did you check that it uses the pipewire replacement and not any of the other jack libraries? You can check this using the command line:

ldd /path/to/your/software

This also tells you whether JACK support has been compiled in.

Edit: Do you use cmake?

pw-jack conflicts with the jack package

No I don't use CMake since I have no reason to. In this case I don't think I'd need it either. What I'm a bit confused about is your goal. Do you want me to use the jack API to make the connections myself? Is there no suppport for that in rtmidi?
