Qt License for Commercial Application
-
@mrjj When i download Qt Opensource and use Qt Creator and leave everything as default, does it dynamic link the libs by its self or do i have to do it myself?

Hi,
Static Qt build for closed source application.
Support from the Qt Company.
Prioritisation of your bug reports.
No need to publish your Qt modifications if you did any (although it would be very nice).
Some additional tools and modules that you may find useful that are not in the OpenSource project. -
I want to verify what understood by me.
I am developing my application using embedded board which already have open source distribution with QT library.
GUI will develop using QT creater-open source and it will display "application is created using QT".I think above effort does not require to make source open for QT GUI Application.
Am i right? -

Am i right?@Jignesh-Patel Yes, For your case, don't care about license.

@Hung-Tran Thanks,
understand the QT license for open source distribution, I have one question for customise distribution.
I have customised Linux distribution to remove unnecessary package and make minimal, We are ready for keep source open of new customise Linux distribution.
I am developing my application using embedded board and install my customise Linux image.
Now, In above scenario. can i use my application as commercial and non open source?Thanks.

@Jignesh-Patel
Yes you can be closed source as long as you dynamic link to Qt.The license model of the customized Linux distribution is not important in this matter.

And unlike what @Hung-Tran wrote: care about the license, using GPL or LGPL also has implications.

Hi @Jignesh-Patel
As long as you dynamically link to (Qt or anything else) LGPL libraries you can keep your source closed and still comply with the LGPL. However if there are GPL licensed libraries that you are linking to, your code needs to be GPL, and thus you need to share your source.
