Hi list,
I was trying Pd-Ext (last stable version) with jack on ubuntu linx, and
got a couple of mistakes. Can someone elucidate on what they are?
this one appears when I try to start Pd -nogui:
"error: JACK error: cannot lock down memory for RT thread (Cannot allocate
memory)"
This one appears when I load a complex patch. It also crashes Pd:
"tk scaling is 1.3187954309449634 Speicherzugriffsfehler pd_gui: pd process exited"
Funnily, Pd+Jack works with the same patch - as long as I start Pd with
alsa, and after loading the patch change the audio to jack.
Thanks as usual,
João
Try a nightly build, I think there are some jack fixes.

ah, so it is really a Pd bug, and not some bad jack oder system settings?

dunno, but "try a nightly build, i think there are some jack fixes" does not necessarily mean "this is a known issue that was fixed only recently"
best would be to try and report (un)success...
"error: JACK error: cannot lock down memory for RT thread (Cannot allocate memory)"
this error seems to indicate that you are lacking real time priviliges (what's the content of your /etc/security/limits.d/audio.conf?)

"tk scaling is 1.3187954309449634 Speicherzugriffsfehler pd_gui: pd process exited"
you could try to produce a backtrace [1]
Funnily, Pd+Jack works with the same patch - as long as I start Pd with alsa, and after loading the patch change the audio to jack.
which would indicate that your patch takes too long to load and jack kicks out Pd....

I can reply later, I can't access the computer where this happened.

the patch does need some time to load, it has to load in a couple of long
samples (up to 5'), load text files with markers that divide the arrays
and generate data structures to display that division... can take some
minutes in XP (will take less on ubuntu, of course).

This means you don't have realtime privilege and cannot start jack in realtime mode. If you chose "yes" to have realtime capability while installing jack, you will have installed a file /etc/security/limits.d/audio.conf, but to make use of that file you need to be a part of audio group.
Group changes take effect after logging out/in.
