Thank you Paul Davis and others again. But I just this day got jackd -v = 0.74.1, the latest Is jackd to be RUNNING on compile?? Now the same error ../libs/ardour/.libs/libardour.a(audioengine.o): In function `ARDOUR::AudioEngine::start()': /home/bart/2ndownload/ardour-0.9beta2/libs/ardour/audioengine.cc:90: undefined reference to `jack_set_xrun_call back' collect2: ld returned 1 exit status I will see if maybe some prior jack install is lying around I used to use ~/bin or even ~/bin/bin by error to ./configure --prefix I leave /usr/local/bin as the default nowadays But I do not think this is the problem.
