[SOLVED]Freely distribute the Qt shared libraries (DLLs)?

anselmolsm

This 'allow updates' requirement is a way to guarantee your proprietary application does not depend on modifications you did in the library - it must be possible for the software to be linked with a newer version of the LGPL library (Qt, in this case :-P), not only to your Qt version. So, if you modify Qt (what is not you case, as you said), to respect LGPL you must submit the changes upstream.

You're absolutely right. Was thinking if this should be some kind of FAQ: "Never ever ask for legal advice on forums, mailing lists, IRC and whatsoever. Consult an IT lawyer." (?)

That might not help either. If you ask three of these guys you will get four opinions....

Haha, ok, point taken, but at least they're supposed to know the matter and you sign agreements with them, whilst on forums you have no guarantees whatsoever.

That's true. It's in most cases better to ask a specialized lawyer than a forum with all that "I believe that..." answers.

But if you ask 3 lawyers, you perhaps get also 4 answers.
Perhaps the Trolls can make a definite statement? That could then also be put to FAQ?

Hi, All, Another question that is can i distribute all files (e.g. my apps, Qt DLLs) use one package (e.g. one NSIS install package, or one zip/7z/tar.gz package) ?
Many thanks!
