Can I use Qt LGPL license and sell my application without any kind of restrictions? [closed]

Solution 1:

Just dynamically link to Qt. If you dynamically link to LGPL libraries, there's nothing to worry about.

If you statically link to them, you can just distribute your object files (not your source code), and you'll be fine.

The idea of the LGPL is that the end user has to be able to replace the LGPL library with a version they want. Dynamically linking to the LGPL library lets you do that, as does statically linking and distributing your object files. So long as you do this, you can sell your closed source program all you want.

Of course, there's more to the LGPL than just this, but that's the relevant part.
