Commercial license vs LGPL license

[Lykurg]

1) I link the app dynamically
2) I do not make any changes to the Qt source

You can make changes, but you have to publish them. (!= the sources of your application)

3) I include a copy of the LGPL license/a link to the Qt source along with my app

So basically, the only benefits I see of having a commercial license are that I can link statically and that I can freely modify the Qt source to my heart's content without having to distribute anything else.

With commercial there is also bundled a support from Nokia.

And if I make no changes, there's nothing at all to publish.

Of course, that's an added bonus.


Other than that, do I have everything right?
When deploying the app, do I have to include an actual copy of the LGPL license (i.e. this file) or is it enough to say that this application is licensed under LGPL, and the provide a link to http://qt.nokia.com/ ?

Right.

I am not a lawyer, and beside: the LGPL is interpreted different in each country. I would ship a copy of the LGPL with my application. It has not to be in the root directory. The link to nokia is a must if you don't want to ship the sources of Qt itself with your application.

If you want to be 100% sure, ask a real lawyer. Otherwise: Nullum ius sine actione! (which means in English something like: no complaint, no redress)

Great, thanks for your help!
