You have probably heard some of the following statements, if you intend to use Qt under LGPL-3.0:
- “You must make the source code of your proprietary application public.
- “You cannot link the Qt libraries statically.”
- “You must allow users to install a modified version of the Qt libraries on your X-ray machine.”
- “You cannot switch from Qt Commercial to Qt LGPL or vice versa.”
- “Qt Commercial gives you complete peace of mind when it comes to licensing.”
These statements have one thing in common: They are all wrong. In my talk, I’ll explain why and how you can safely use Qt under LGPL-3.0 on embedded devices – as thousands of companies do.
