Hmm, I don't even get that far. I've tried the last 3 versions of pd on RedHat 5.2 (using all their latest updates) and every one of them pretty quickly freezes the whole system in a Tk file-open dialog. I can't even transfer to my character-based virtual terminals or reboot with control-at-delete! I also tried the latest Tcl/Tk (8.05) with the same results.
Mhmm, do you mean version 0.23, 0.24, and 0.25 ?
I built and tried the following, the last one is from MP's site:
/usr/archive/pd_0.24.tar.gz /usr/archive/pd-0.25TEST3linux.tar.gz /usr/archive/pd-linux-0.25TEST4.tar.gz
First of all never call pd under user root. (We might add a switch for enabling high priority, as this happens quite often) The freeze of your machine should go away.
Unfortunately I haven't been calling it as root. :(
Your problem might be related (puh, .. again ) to the audio drivers. (Or possibly the way I access them through very short audio buffers) This can cause a hang in the pd main process, which is most commonly the problem in these cases (Nothing to do with your Tcl/Tk version).
I doubt that's the problem in my case. Coincidentally, I've done a lot of work with buffer configuration for my audio driver. :)
You might try the -dac or -nosound switch on version 0.24 or it's corresponding -noadc in version 0.25.
OK..I'll give those a try.
What soundcard, kernel version, sounddriver do you use ?
It's a PCI128 soundcard. My kernel is the latest update from redhat: 2.0.36-3. I *did* modify the sounddriver to fix a bug in the mixer map.
As you probably realized, between version 0.25TEST3 for linux and 0.25TEST4, we made a switch of responsibilities for the linux sounddriver code. We therefore have two rather different versions (TEST3, which is on ftp://wonk.epy.co.at/pub/pd/linux/ and version 0.25TEST4, which is the original version from Miller). Both of them are considered to really be TEST versions, as in general it is hard to predict how the Linux sounddrivers behave under "realtime" conditions, and we need feedback there as we can't possibly test on all soundcards, with all drivers.
If I can get PD working here, I can definitely help. I'm working on real-time sound software myself. :)
