Hey I'm having an issue where if I load the Gui and open my patch from the desktop of my RPi, everything loads just fine but when I try to open my patch from a script without the GUI, it loads but without the libraries. The console shows .x14c0550: no such object. I am trying to load freeverb~, and a few cyclone objects, specifically cyclone/split, cyclone/mean and cyclone/reson~. Any clues would be great. Thanks!

script is this:

pd -nogui /home/pi/Desktop/theOther/theOtherV5.pd &

@jenkutler You could try something like........ (it's a maybe...?)

pd -nogui -path root\path_to_\pd\extra\cyclone -lib cyclone /home/pi/Desktop/theOther/theOtherV5.pd &

and if that works then add other libraries in the same way. The Gui pref file normally takes care of all that.

Hey David,

Thanks so much for your reply! I tried modifying the script as you suggested and a few variations on it with no luck although a slightly different outcome. Now the error I get for the cyclone objects is "maximum object loading depth 1000 reached" which I read in another post is related to pd being unable to find the setup() function mapped to the classname. Any thoughts on that?

Thanks!

@jenkutler I am not sure at all.
Maybe just the path to the Pd folder then.....
Or just the path to /extra........?
and not the path all the way to cyclone.

Normally the path to the "extra" folder where the libs are stored is automatically set. But maybe not with -nogui........?
It is set with the switch -stdpath
There is more info here....... http://write.flossmanuals.net/pure-data/advanced-configuration/
You could try to set it, and that might be all that is necessary?

pd -nogui -stdpath -lib cyclone /home/pi/Desktop/theOther/theOtherV5.pd &

But the real question is why the -nogui switch is breaking Pd.
Grubbing around for other problems with -nogui finds that patches are normally loaded after the Gui has built (there is a delay so that the Gui can complete).
But with -nogui the patch is loaded before Pd has connected all of its parts. audio, midi etc. and maybe its libraries?
So maybe ignore all of the above.
If there is a way to delay the opening of "theOtherV5.pd" in the script then that might solve the problem.
Also Pd "knows where it is" from its command line...... and maybe you are not invoking the normal shortcut with your script.
So maybe.....

root/path_to_pd/pd -nogui /home/pi/Desktop/theOther/theOtherV5.pd &

All straws clutched I think.
David.

Hey David.
Thanks so much for your response. After a crazy amount of hours I have worked out a way to get it all to work together. I tried every which way of creating flags to get those libraries to load and ultimately I gave up. I ended up installing Purr-data pd-l2ork which seems to be generally more stable than vanilla and happens to load all of my libraries automatically on start regardless of whether they're needed or not. The issue I ran into then was that on RPi, you need jackd to route MIDI. Unfortunately, jackd2 doesn't run on raspberry pi. I fought with it for a while, tried some tricks from forum posts that say to use jack 1.0.8 but I still couldn't get it to work. I use alsa aconnect on some other projects running on pi and I thought I would give it a try. Though the device port numbers change every time you boot up depending on what peripherals you're using, I found that you can also aconnect using the device name. The trick then became trying to find a way to run not one script on startup but two scripts. After fighting with /etc/rc.local and crontab for some hours, I found that even when I got both things to run, I ran into all kinds of alsa errors, mainly the one where PCM cannot open, blah blah blah. So I've been sitting in front of Pd for so long that I'm starting to have dreams about Pd and half awake, I wondered if a) its possible to specify preference settings with objects and b ) if its possible to run a shell script from an object in PD. Then I only have to run the one script on start. I found an object {shell] that allowed me to run my aconnect stuff in the shell after loading my patch. Then I saw a brilliant post that explained how to change preferences using [r pd] and [print] . If you make changes to your preferences, the pd window spits out some numbers that specify the setting you just saved. Then you can copy and paste those values into a ;pd message and change your preference with a loadbang. I had to stagger the different messages with various [delay] objects but the thing works.

@jenkutler That's brilliant. I only built one project on the RPI...... it controls all my home entertainment, lighting etc. As a Linux noob it took me forever.
There are only a couple of people on this forum who know enough to really help (I am not one of them) but there are more and more Pd fanatics using the RPI (in all versions) for effects pedals, permanent installations, school projects etc. There is usually more help to be found on the RPI forums than here.

If you get a moment to post up a tutorial for the problems that you have solved then that would be great..... as I have seen many posts with exactly the jack and shell problems that you have overcome.
David.
