gentoo + jack + dbus = broken
Linux + gentoo + jack-audio-connection-kit + dbus use flag enabled = doesn't work any more.

Okay... Just a personal note to remember.

DO NOT COMPILE jack-audio-connection-kit WITH THE dbus FLAG ENABLED!  IT REMOVES jackd WHICH IS WHAT  qjackctl USES TO START THE JACK SERVER.

So... Unless I'm missing something, this is pretty much the status quo for me - because this has bitten me TWICE now.  I want to upgrade JACK for my studio's DAW, and the dbus flag breaks qjackctl by removing the jackd binary.

So...  Don't compile jack-audio-connection-kit with the dbus flag enabled.

(Why is that flag even there?  Am I missing something?)

grep -ir dbus /usr/portage/media-sound/jack-audio-connection-kit/

 

I don't use Jack but the official Gentoo ebuild doesn't seem to have a DBus flag, maybe you're getting this from an overlay?

Yeah.. I'm using jack 1.9.5 - and that's the one I need to use for pro-audio.  I'm getting it from the pro-audio overlay.  This is more of a personal note than anything.

If you're using an overlay, you should follow the overlay's newsletter. Then you would have read that what you want is enabled by the "classic" USE flag.

JACK2 (the C++ implementation) comes with a nice DBUS api which is considered the standard api if you enable it. It isn't necessary to start jackd anymore, starting JACK can be done by a DBUS call. It should be possible to configure QJackCtl in a way such that it does exactly that.

It's possible to have the "classic" and the "dbus" use flag parallely and have both the old jackd binary and the new shiny DBUS JACK (although I didn't test this). Have a look here: http://www.mail-archive.com/proaudio@lists.tuxfamily.org/msg02963.html
