Qt Licenses

[ClaraCaste]

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.
