QT5 for Notepadqq on Raspberry



  • Hello,

    I installed qt5 to run notepadqq on the raspberry with the following commands:

    sudo apt-get install qt5-qmake
    sudo apt-get install -y libqt5webkit5 libqt5svg5 coreutils
    sudo apt-get install -y libqt5webkit5-dev libqt5svg5-dev qttools5-dev-tools

    Next, I downloaded notepadqq and tried to configure:

    ./configure --prefix /usr --qmake /usr/lib/arm-linux-gnueabihf/qt5/bin/qmake

    I received the following errors:

    checking for Qt5WebEngine library… not found!
    checking for Qt5WebEngineWidgets library… not found!
    checking for Qt5WebSockets library… not found!
    checking for Qt5WebChannel library… not found!

    I assume, some qt5 library or libraries are missing, but was not able to figure out, which ones are required by notepadqq, despite extensive research.

    Do you have any idea how to proceed?

    Thanks in advance!

    Hi and welcome to devnet,

    You installed the QtWebkit modules while Notepadqq requires the QtWebEngine modules as well as QtWebSocket and QtWebChannel.



  • Thank you for your response and welcome.

    Could you indicate me the lib and dev-lib names or refer me to the appropriate lib documentation? I have unfortunately not be able to figure out the correct commands and not found the reference in the documentation... Thanks...

  • Many thanks for your answer and time. I have tried a couple of combinations to install the libraries, but I always failed... the ones you indicated both throw error e - package not found:

    sudo apt-get install -y qtwebengine5
    Paketlisten werden gelesen... Fertig
    Abhängigkeitsbaum wird aufgebaut.
    Statusinformationen werden eingelesen.... Fertig
    E: Paket qtwebengine5 kann nicht gefunden werden.

    Thanks again for your help!

    I'm not sure whether it's going to work but you can always try to get it from the Debian project.

    Otherwise, you'll likely have to build the module yourself.



  • thanks for the advice; sounds a little bit too complex for me as a newby though ;-)
    Best regards & have a nice evening...
