Mumble 1.4.0

Installare Mumble ultima versione su Raspberry Pi

Come abbiamo visto nell’articolo VoIP e stazione remota, Mumble si presta in modo egregio alla realizzazione di un sistema server e client VoIP per attività radio. Mumble è disponibile per diversi sistemi operativi, tra i quali appunto Raspbian (Raspberry Pi OS), che lo mette a disposizione per l’installazione dal suo repository. Purtroppo la versione qui presente non è tra le più aggiornate, al momento Mumble è alla 1.4.0 mentre sul repository è fermo alla 1.3.0. Vedremo quindi come compilare Mumble per RPi direttamente dal codice sorgente, il procedimento è lungo, richiede un po’ di tempo, ma nulla di complicato.

Installare le librerie

La maggior parte delle librerie necessarie alla compilazione sono già disponibili sul repository Raspbian.

  • Dopo aver aggiornato l’elenco dei pacchetti
sudo apt upgrade
  • Installare le librerie
sudo apt install \
build-essential \
pkg-config \
qt5-default \
qttools5-dev \
qttools5-dev-tools \
libqt5svg5-dev \
libboost-dev \
libssl-dev \
libprotobuf-dev \
protobuf-compiler \
libcap-dev \
libxi-dev \
libasound2-dev \
libogg-dev \
libsndfile1-dev \
libspeechd-dev \
libavahi-compat-libdnssd-dev \
libzeroc-ice-dev \
libpoco-dev

Installare CMake

Mumble utilizza il compilatore CMake, richiede la versione 3.15 o superiore. Sul repository di Raspbian Buster è attualmente disponibile la versione 3.16, possiamo quindi installarla semplicemente con il comando:

sudo apt install cmake

Compilare CMake da sorgente

Nel caso in cui si desideri installare l’ultima versione aggiornata di cmake, occorre compilarlo da sorgente.

wget https://github.com/Kitware/CMake/releases/download/v3.21.2/cmake-3.21.2.tar.gz
  • Scompattare l’archivio
tar -zxvf cmake-3.21.2.tar.gz
  • Rimuovere l’archivio compresso
rm cmake-3.21.2.tar.gz
  • Entrare nella cartella
cd cmake-3.21.2
  • Compilare CMake
./bootstrap
make
sudo make install
  • A questo punto eseguire il reboot del sistema
sudo reboot

Compilare Mumble

git clone https://github.com/mumble-voip/mumble.git
  • Entrare nella cartella
cd mumble
  • Recuperare ulteriori librerie
git submodule init
git submodule update
  • Creare una cartella per la compilazione
mkdir build
cd build
  • Preparare i file per la compilazione
cmake .. -Dspeechd=OFF -Dplugins=OFF -DOPUS_DISABLE_INTRINSICS=ON

Per risparmiare spazio e tempo di compilazione sono state aggiunte alcune opzioni. -Dspeechd=OFF disattiva il supporto di sintesi vocale con Speech Dispatcher, altrimenti andrebbe installata anche la libreria corrispondente e i campioni vocali. L’opzione -Dplugins=OFF disattiva i plugin per l’audio posizionale sui videogiochi. L’opzione -DOPUS_DISABLE_INTRINSICS=ON disattiva il supporto di registrazione nel formato ogg, purtroppo non supportato dalla libreria libsnd di RPi. Se non occorre compilare il server, aggiungere -Dserver=OFF. Per ulteriori opzioni di compilazione fare riferimento alla pagina CMake options.

  • Compilare l’eseguibile
make

Alla fine della compilazione, che richiede diverse decine di minuti, all’interno della cartella build vi ritroverete l’eseguibile mumble pronto per l’utilizzo.

Collegamento sul desktop

Vediamo ora come creare un collegamento sul desktop per tenere il programma a portata di mouse.

  • Aprire il File Manager, andare nella cartella /home/pi/Desktop e creare il file Mumble.desktop
  • Editare il file inserendo il seguente contenuto
[Desktop Entry]
Name=Mumble
Comment=1.4.0
Icon=/home/pi/mumble/icons/mumble.xpm
Exec=/home/pi/mumble/build/mumble
Type=Application
Terminal=false
Encoding=UTF-8
Categories=None;
  • Salvare e uscire

Al prossimo riavvio vedrete apparire sul desktop l’icona di Mumble e con un doppio click sarà possibile mandarlo in esecuzione.

  1. I followed your steps but used CMake V3.20.2 which latest.
    Everything went well until I got to the Mumble CMake step. It cannot find the Poco component. Did I miss installing a library?

    Thank You.

    Kevin

      1. I got it. All I needed to do was run this:

        sudo apt-get install libpoco-dev

        After that the rest of the build went very smooth.

        Thank you for the great tutorial!

  2. Mine was fine until right after cd build. this is what happened:
    pi@rigpi2:~/mumble/build $ cmake .. -Dspeechd=OFF -Dplugins=OFF –
    CMake Error: Unknown argument –
    CMake Error: Run ‘cmake –help’ for all supported options.

    What to do now?

    1. Hi Alan,
      your copy and past was partial, you miss the words after the last “-“:
      cmake .. -Dspeechd=OFF -Dplugins=OFF -DOPUS_DISABLE_INTRINSICS=ON

      1. OK I tried that.

        pi@rigpi2:~/mumble/build $ cmake .. -Dspeechd=OFF -Dplugins=OFF – DOPUS_DISABLE_INTRINSICS=ON
        CMake Error: Unknown argument –
        CMake Error: Run ‘cmake –help’ for all supported options.

        1. OK. I found that I had and extra space before DOPUS. But now this happens:
          pi@rigpi2:~/mumble/build $ cmake .. -Dspeechd=OFF -Dplugins=OFF -DOPUS_DISABLE_INTRINSICS=ON

          1. OK progress. I had missed the qttools5-dev-tools library. Went back and installed that. Now cmake is working. It is at 80%. Thank you.
