Commercial application using Qt [closed]

Question

I am a new user of Qt...I want to know can I create commercial and closed source applications using Qt4(LGPL Licensed)? and also what is the difference between Qt4(LGPL version) and Qt4(Commercial version)?

Thanks in advance...

Answer 1

The LGPL allows for use in proprietary products. One thing you do have to do when using an LGPL library is allow the end-user to replace the library code with their own (modified) equivalent, implying dynamic linking to your actual application in most cases.

That's why the commercial edition of Qt touts static linking as one of its features, on top of the other features relating to development support.
