How to install QtCharts module on Qt 5.5. OS is Ubuntu 16.04 lts



  • I am a newbie for Qt. My embedded device support Qt 5.5 and i am developing on Ubuntu 16.04 Qt 5.5. I am trying to run a QtCharts sample but it is not installed on 5.5 version of Qt.
    i downloaded module from "https://github.com/qt/qtcharts" and tried to install just as it says in readme file but it did not work. am i doing it right?
    How can i install this module on Qt 5.5 ?

    Thanx in advance

    QtCharts was a commercial-only module up to Qt 5.6. It was open sourced in Qt 5.7 but under GPLv3 license, which is probably not a good license for your project. So, to use QtCharts in Qt 5.5, you need to get Qt commercial license.

    Or update your Qt to a higher version (that's a very good idea anyway - a ton of new features and bug fixes have been implemented since 5.5) and distribute your whole app under GPLv3.



  • On my embedded device Qt 5.5 is installed and it does not supoort newer versions.
    So is it impossible to use QtCharts on this device and Qt version?

    I'm pretty sure it would support higher versions just fine, you may need to compile Qt yourself - but that indeed might be a bit hard.

    So it seems. Unless you get in touch with Qt Company and they help you - that will be costly though, as Qt 5.5 is long, long past it's End of Life date.

    There are other chart libraries for Qt, by the way: Qwt, and you can integrate JavaScript charts (example: https://github.com/milosolutions/mcharts).
