    Good afternoon,

    I would like to know about QT licenses. I would like to develop a QT based app liking dinamically qt libraries.

    I'm not sure if I have to pay or not if I would in the future make money with the developed app.

    I also would like to use QT creator IDE with Qt5. ¿Is there any necessity of paying for using this IDE with Qt5?

    Regards,

      If you fulfill LGPL requirements and use LGPL parts of Qt, then you don't need to pay for license and you can make money with your app.

      No need to pay for Qt Creator.
