Qt Licenses

  • Hello !

    I'm using Qt5.6 and I would like to create a commercial application.
    I dynamically linked with Qt and I do not share my source code.
    I have read that I can use Qt using a LGPL license, is it true ?

    Thank you !

    Hi and welcome
    Yes, most of us use Qt with dynamic linking to satisfy the LGPL
    so as far as I know, this should be fine.
    Disclaimer: Im not a lawyer
    This is for Widget Qt application.

  • Thank you mrjj !
    So the commercial license is necessary just for static link ?

    Well also for mobile apps and publish to app stores and other cases.
    It also give direct support and pro help if needed.
    So there are many benefit to being a a Pro user.

    But if you dynamic link your desktop app, it should be fine using the open source.

  • Thank you very much
