[Development] Qt open source license in product

[Attila Csipa]

Hi,

Disclaimer: IANAL

No, the LGPL does not require the release of *sources* of your 
application. However, there are extra requirements to the *binaries* 
(especially related to being able to replace the Qt libraries you're 
providing). In general, if you're using Qt libs from a user accessible 
directory/source, you're likely ok. This is especially tricky on mobile 
- in my (IANAL) reading, Ministro is OK, but bundling the Qt libs within 
apps is a grey area at best unless you take extra precautions regarding 
the disclaimers/instructions.

Best regards,
Attila Csipa
