INSTALL for PIBOX V3 on a Ubuntu Laptop/Desktop ( 18.04 or 20.04 )

Pibox V3 app was developped by http://p-node.org and in particular by jack@rybn.org and it is aimed at providing a streaming station/solution on Raspberry PIs.

It can also act as a radio FM transmitter on Pi boxes, but this part will not be available on PCs.

Here are the instructions to install it on a regular Ubuntu system :

PREREQUISITES

A ubuntu 18.04 or 20.04
Tools : git, python3, node.js, npm

 ** on Ubuntu 18.04, we used :
    git 2.17.1 
    python 3.6.9 
    node.js v12.10.0 
    npm v6.9.0

IMPORTANT !!

You must install and run under the account that started the gnome session to be able to connect to pulse audio.

So, use your normal account and not the pi account like indicated in some p-node manuals.

My user here is chevil, my usual account.

INSTALL

Pibox V3 consists of 2 parts :

* a back-end which is a python app

* a front-end which is an angular/node.js app

Adjust pulse configuration

edit ~/pibox/pibox_v3_back/app/main.py

change :

/etc/wpa_supplicant/wpa_supplicant.conf

to :

/etc/dbus-1/system.d/wpa_supplicant.conf

change :

/sys/class/ieee80211/phy1/device/net

to :

/sys/class/ieee80211/phy0/device/net

 * Note : this could be wrong, this depends on how many network cards you have in your system, so check what is in /sys/class/ieee80211

Setup the front-end

 cd ~/pibox/pibox_v3_front
 rm package-lock.json
 npm i

Restart your machine

 reboot

Start the back-end

 cd ~/pibox/pibox_v3_back
 python3 app/main.py

* Note : it will ask your password here to execute commands with sudo, it's normal

Start the front-end

 cd ~/pibox/pibox_v3_front
 npm run start

Epilog

That's it !

Your Pibox V3 UI should be available at : http://localhost:4200

Err, Wait, no, There is a problem on Ubuntu 20.04 :

The libshout ( 2.4.3-1 ) has a regression and does not work ( you cannot send stream out ),

so you have to use an older version of libshout, here is how you can install it, overriding the official one :

 sudo apt-get install xz-utils wget
 cd /tmp 
 wget http://mirrors.kernel.org/ubuntu/pool/main/libs/libshout/libshout3_2.4.1-2build1_amd64.deb
 ar xv libshout3_2.4.1-2build1_amd64.deb
 xz -dc data.tar.xz | tar xv
 sudo cp ./usr/lib/x86_64-linux-gnu/libshout.so.3.2.0 /usr/lib/x86_64-linux-gnu/
 sudo ldconfig -v

Now, it should be ROLLING !!
