    Hi

    I noticed QT includes a lot of third party software by looking at:
    https://doc.qt.io/qt-5/licenses-used-in-qt.html

    I am unsure of the license requirements for these included third party components (I am not a lawyer).
    Note: I am using the open source version of Qt. Not commercial.
    E.g. qtlocation has quite a lot of third party components included: https://doc.qt.io/qt-5/licenses-used-in-qt.html#qt-location.
    When shipping software that uses qtlocation, what should we:

    • list as license ? Just for qtlocation itself, or also mention the third party included software ? Or maybe just for those that are actually used ? And if the included third party has itself included third party software, should we include that ?
    • what license files files should we include ?

    I'm using Yocto for building my rootfs including Qt libraries.
    Currently, https://github.com/meta-qt5/meta-qt5 , does (almost) not include any license for third party components.
    If I include qtlocation to my rootfs, Yocto (incorrectly?) does not include ISC, MIT, Boost and the rest of the licenses for the third party include software.
    Legally speaking; Should it ? And should we include the license files ?

      I think so, yes.

      (but of course please ask a lawyer etc.) ;-)

      Embedded board and open source Qt? Are your users able to replace Qt libs (LGPLv3) or is your code GPLv3?
