Installing QT5 on raspberrypi



  • Hello everyone,

    I want to install Qt5 on my "RaspberryPi", using "armv6l"- (linux, debian).

    I used the terminal and install Qt with the following comand: "sudo apt-get install build-essential libgl1-mesa-dev" and it runs.
    My first question is, do I now have installed the whole qt library? I can't find it on my disc.

    And my second question is, how can I install the qt creator? Is there a apt-get-comand like above??
    I allready try it with the installer: " Qt 5.5.1 for Linux 32-bit or 64-bit" and "Qt Creator 3.5.1 for Linux/X11 32-bit or 64-bit", but I just get an error "bash .... cannot execute binary file".

    Thanks for your time and answers.

    with greedings Jeff

    Hi and welcome to devnet,

    You have two options to get Qt 5 on the Raspberry Pi:

    1. Cross-compile it
    2. Build it natively

    The failure you get with the installers is because they are built for x86 and x86_64

    @Jeff_T69
    Debian has prebuilt Qt5 (5.3.2 in the raspbian version, so it's a bit behind in versions) packages available. I'm not a debian user, but I think the package to install is libqt5.

    I have no idea how well QtCreator will run on a RaspberryPi, but you certainly can try. (normally people cross compile on their PCs) The package is qtcreator in debian, so try apt-get with that.

    However if you really want to learn things, go with what @SGaist suggest, and cross compile the latest Qt on your PC.



  • Thank you for your fast reply.
    You are right, I see the problem.
