Hello! I hope you will indulge this familiar game of trying to get external libraries to load. It's not my first time, but seem to frequently bang up against a new hurdle every few months.

It's a brand new raspberry pi, on which I have downloaded PD 0.51.4 and I have used Deken to install else.

Some of the else objects are working great, for example [adsr~] or [quantizer], but many other objects in the same externals library are not found, for example [quantizer~] or [keyboard] rendering a lot of the objects useless (as many of the objects contain and rely on these other else objects). If some of the objects are working then the library is found, right? Why would some be working and not some others?

I have added a specific path to the else library in preferences. I'm using [declare -path else] and [declare -lib else] objects in my patch and it's not making any difference.

I'm at a loss- does anyone have any suggestions? Thank you!

@Dizzy-Dizzy You are right... it should work.
Sometimes giving the directory in the object name works.....
Try creating [else/quantiser~] and [else/keyboard].....
David.

hi, please get Pd 0.55 so objects can work. I think you're missing multichannel support! I don't have a pi to test things but I'm here to help

Thanks for both your responses and help.

Hi @porres - I just downloaded Pd to my pi two days ago using the terminal command "sudo apt-get install puredata" - I assume that the latest version available for my pi was downloaded at that point? I guess I've always assumed that it's the latest version when I download software to my pi this way.

To verify that I have the latest I used the "sudo apt-get upgrade puredata" command in the terminal and got the message "puredata is already the newest version (0.51.4-1)"

Is Pd 0.51.4-1 the most recent version for a Pi4B, I wonder?

@whale-av thanks for the reality check! I have also been giving the directory name in the object itself (and this is also how they are named in the help files for each object), but they still won't work. When I declare the library I get this message in the Pd window:
/home/pi17/Documents/Pd/externals/else/else.pd_linux: /home/pi17/Documents/Pd/externals/else/else.pd_linux: undefined symbol: pdgui_vmess

@Dizzy-Dizzy You should be able to build the latest..... Pd 0.55..... for your rpi from the source code... the first download on this page........ https://puredata.info/downloads/pure-data
I believe it is quite a painless procedure in Linux.

That's referring to the latest version in your Linux distro's package manager. Package managers aren't guaranteed to have the latest versions of everything. So there does exist Pd 0.55, but the package manager doesn't have it.

Agreed that Pd is one of the easiest packages to build. Readme instructions are straightforward.

hjh

building ELSE is also supposed to be painless by the way

Thanks all, I've been using Pd for some time now but haven't ever tackled a build. I will give this a try. If anyone can point me to any resources on a step by step build, I'd be very grateful!

EDIT: OK, I downloaded the source code at the link provided by David, and I see the install instructions document in there- I will start there.

@Dizzy-Dizzy
https://wp.nyu.edu/computer_music/installing-pd/

But I doesn't explain it very well.
You might see in the tar.gz download a folder packages/Linux_make.
Inside probably a readme.
There should also be a file "makefile".

The readme will have instructions something like this....... README
David.

OK, I followed the instructions in the readme doc:
file:///Users/bencoleman/Downloads/pd-0.55-0/doc/1.manual/x6.htm

Did the full install procedure, first the linux specific steps, and then the general autotools build steps

And although I see Pd listed under sound and video applications in the drop down menu as though it is installed, it will not open. If I try and open it in the terminal with the command 'pd' or 'sudo pd' I get the following message:
sh: 1: wish: not found

Can anyone help me understand what is happening? Is there a way for me to verify that pd 0.55-0 works on Raspbian GNU/Linux 11 (bullseye), which is the OS running on my new Pi 4B?

I'm a bit stumped! Thank you for any and all help.

@Dizzy-Dizzy I do have a RPI but I am not very familiar with Linux.
On my RPI3B Raspian... stretch I think....the wish executable is in /usr/bin.... and also the wish86 executable.
wish86 was probably installed when I installed Pd via apt-get.
First check that you have them on your system........I think they must be there because you had Pd installed before.
Then, so far... the only help I have found is here..... https://askubuntu.com/questions/515610/wish-missing-but-tk-is-installed ........ but I find it strange that your error was for wish and not wish86.

If you don't find wish86 in that folder maybe you can simply copy it from the source code folder...... but it probably needs to be installed so..... sudo apt install wish86.... and maybe also sudo apt install wish.
... from this page....https://wiki.tcl-lang.org/page/Raspberry+Pi

I hope I am helping, but I am not confident.
Pd starts and then uses wish to create the on-screen windows and draw the patches..... so your build might well be good but without wish nothing will be drawn to the screen.
David.

@whale-av thanks for all your support.

I'm looking in usr/bin and both wish and wish8.6 are there already!

I wonder why it's not finding it...

sudo apt install wish confirms:

pi17@pi17:~ $ sudo apt install wish
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'tk' instead of 'wish'
tk is already the newest version (8.6.11+1).
tk set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I must confess this is starting to get a bit beyond me, it seems this build is not as simple as it promised!

OK, I ran

sudo apt-get --purge autoremove puredata

And then started all over again from the beginning, doing exactly the same thing, and this time it worked! Very strange.

All this aside, the good news is that all of the ELSE library now seems to be working! Phew, what a trip. I'm so grateful to everyone here for walking me through this.

@Dizzy-Dizzy That's good news, and thank you for posting how you solved the problem.
There are a lot of people using Pd on the RPI and your solution will be very helpful into the future..!
David.
