Can a kind soul walk me through the process of installing and running pd-vanilla under Fedora25 please. I DLd tar.gz from Miller's site, I read and followed the INSTALL.txt, installed automake, autoconf and libtools, and it still won't run; this is so frustrating for a command line n00b. Is there a simple, transparent and reliable method?

Brendan

Apparently Pd is installed but you can't get real-time priority (this is what the message "priority 8 scheduling failed." means). Also, it looks like you don't have wish installed, which is where the GUI runs (if I'm not mistaken). Try installing wish from Fedora's repositories and see what you get.

Hi
I installed wish (the tk rpm, from rpmfind.net, for anyone else with the same issue), and PD now runs; thank you very much. PD still gives me this error though:
priority 6 scheduling failed; running at normal priority

Can I safely ignore it?

Brendan

I found this:
https://www.mail-archive.com/pd-list@lists.iem.at/msg03032.html
Which describes how to add user to a group, then edit a file: /etc/security/limits.conf

I don't feel safe editing conf files, and unsure about creating/adding groups.

Should I install the planetccrma kernel? I'm not too concerned about realtime scheduling right now

Brendan

If planet ccrma has a real-time kernel, then go for that. I can confirm that editing the limits.conf file won't harm your system. Only, when you run Pd (and Jack if you run it with it), your computer won't be able to do some things like play a Youtube video, for example.
But you'll need these permission (and to add yourself to the audio group) in order to get real-time. You'll definitely need a real-time kernel as well to run on real real-time.

Hi
thanks for the advice - could you possibly advise me how to take ownership of a 'locked' file such as limits.conf; I'm unable to edit it via the GUI, and don't know how to do it within the Terminal.

Many thanks
Brendan

sudo nano /etc/security/limits.conf
This will ask you for your user password and will open the file in nano. nano is a text editor that opens up in the terminal. It's very easy to use, you'll probably find sufficient sources about it online.
Note that this is not for Jack. If you've installed Jack with real-time priority, then there should be another file, /etc/security/limits.d/audio.conf or something like this. You should probably edit this file as well, writing the same stuff at the end of it, as you did with /etc/security/limits.conf

Alexandros
many thanks for this, I now feel happy to pursue this on my own; I will report back soon, confident that I can mark this "solved"

Hello, I am new to puredata and saw this post, I am also having difficulty installing pd 0.47-1 but on Linux Mint Rafaela, I am only able to download version 0.45.
I am very new to Linux and not sure if I am doing something wrong.
I have been entering
"apt-get install puredata"
but each time it says that the newest version is installed.
Does this mean that 0.47 is not compatible with my version of Mint?

@OJO This means that the repositories of your Linux distribution have an outdated version of Pd, which is what you get with apt-get install.
If you want to get the latest version (and you probably should get it), go to Miller's website and download the source, then compile after you make sure you have all the necessary dependencies (check the INSTALL.txt file).
