    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.

        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.
