I don't know if this is a problem with PD or with JACK but...
I have jack 1.9.5 (package from planet-ccrma fedora 13/64bit) and PD compiled from source (miller puckette website).
I compiled PD with ./configure --enable-jack=yes --enable-alsa=yes
When I start JACK and then PD with pd -jack
I get:
jack_client_new: deprecated Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started
It works OK with ALSA if I start with just "pd". But nothing with JACK.
Any idea what goes wrong here..?
