Hi there,

I'm trying to get pd-extended running on my Raspberry Pi.

Firstly - I have to say I'm NOT good with linux. It's not intuitive to me and I've been finding it tough trying to learn enough to get the pi up and running with what I want to do. I am happy using the CLI but I don't know many of the commands and any simple task seems to take me some time to do, so please don't assume any decent level of prior knowledge!

Here is what I've done:
1. Downloaded a fresh copy of the latest version of Raspbian Wheezy from http://www.raspberrypi.org/downloads
2. Followed the instructions at http://puredata.hurleur.com/sujet-7277-puredata-running-raspberry:
i. Open the sources list for editing (sudo nano /etc/apt/sources.list)
ii.add "deb http://apt.puredata.info/releases wheezy main" to the list
iii.Ctrl + X to exit, answering yes to save changes
iV. Refresh the apt-get (sudo apt-get update), ignoring the warning at the end
v. sudo apt-get install pd-extended
3.Once pd-extended has been installed I then run into a big problem. I can't open it!

I get the following text if I try and run pd-extended:

$ pd-extended -verbose -stderr -d 3
Input channels = 2, output channels = 2
set pd_whichmidiapi 2
Pd-0.43.4 ("extended") compiled 00:11:03 Jan 25 2013
port 5400
TCL_LIBRARY="/usr/lib/pd-extended/lib/tcl/library"
TK_LIBRARY="/usr/lib/pd-extended/lib/tkd/library" wish8.5 "/usr/lib/pd-extended/tcl//pd-gui.tcl" 5400
Waiting for connection request...
/usr/lib/pd/bin/pd-watchdog
watchdog: signaling pd...
watchdog: signaling pd...
watchdog: signaling pd...
watchdog: signaling pd...

The watchdog messages continue indefinitely (I've left it running for the past half hour and it's done nothing else but spew them out). If I pull power (the only thing I can think of to reboot the pi in this situation) then the file system corrupts and the pi puts the filesystem into read-only or crashes with a kdb error on reboot. This then requires re-flashing the SD card and starting again.

I've been round this loop a couple of times now and can't see that I'm making a mistake following the instructions.

Please can somebody advise me:
1. what's going on!?
2. how can I avoid damaging the filesystem in these situations?

Cheers,

Paul

I'm going to try this too so I'll report my results as soon as I can (may not be soon). But you have tried to install 0.43.4 according to this link http://puredata.info/downloads/pd-extended-0-43-3-on-raspberry-pi-raspbian-wheezy-armhf 0.43.3 is the alpha release for Rpi Wheezy, you may want to try that instead. This is what I will be trying.

Well I tried following the install instructions I linked above for pd-extended but I couldn't get it working. There were a bunch of missing dependancies I'm sure that didn't help. I thought I would try Miller's Pd build instead: http://pd-la.info/pdpi/

It's vanilla Pd not Pd-extended but I've heard GEM doesn't work on the pi yet anyway. This is a full image for the pi with Pd already on it and it works great with the onboard audio! I haven't tried to run a full on patch yet but its running and spitting out sound! I'm pretty happy the only issue I've got is that new pd files open with their taskbar too high up on my display so I can't move them around and I can't figure out how to fix that.

Now to find the [gpio] external and get it working!

Also I used an 8gb formatted SD card and I have one of the original 256M RAM Pis.

Thanks Glitchpop - I will look into pdpi in the mean time while I try and sort out whatever the issue is that I'm currently experiencing.

There are videos online of people running pd-extended on pi so it must be possible.. I just can't seem to get it working following the instructions that should work!

if a window is too high on the screen for you to move it by its bar, you can hold alt while clicking and dragging anywhere in the window to move it. this works by default in most gnome setups as well as on the pi.
