A6 : No Jack choice [solved]

Hello,

Please excuse my english… I speak French.
I’m new in Ardour. I have downloaded and complied A6 from the sources yesterday.
When I want to choose the Audio System, Jack is not proposed (only Alsa, Pulsaudio or None). Even if I start Jack before (see screenshot with jack running and hydrogen connected).

Any idea ?

System : Ubuntu 18.04.4 LTS, jackdmp version 1.9.12, QjackCtl 0.4.5

It looks like you have compiled it without JACK support. In Ardour check Menu > Help > About > Config, and look if “JACK Backend: True”.

If it’s “False”, most likely you did not have the libjack-dev or libjack-jackd2-dev package installed when compiling Ardour.

JACK Backend: False :man_facepalming:
Thank you for your help. I will recompile asap

You can also explicitly specify this, instead of auto-detecting:

./waf configure --with-backends=jack,alsa,pulseaudio,dummy --optimize ...etc...

but you still need the jack-headers from the libjack-dev package.

Recompiled, and now everything is OK. Thank you very much !
