Hi,

If I want to develop a proprietary software by using Qt LGPL version...

I must make sure these things:

1) Dynamic linking only (when no changes to Qt itself)

2) Say somewhere in my software that i am using Qt (for example under the Help menu->About Qt)


Then here: http://blog.qt.nokia.com/2009/11/30/...sing-decision/

If you are shipping an executable, you must include any data and utility programs needed for reproducing the executable (i.e. must provide components needed to recompile with a new version of the library) unless such data and utility programs are normally distributed with the major components of the operating system on which the executable runs
So
3) i have to include anything to reproduce the executable? What does this concretely mean? I ship the object files?? *.o? or how do you achive this? (perhaps theuser could just replace the dlls)

The Nokia Exception says that you can include up to 5% of the entire Library? Does it mean i can't create infinite amount of Buttons derivated from QButton class?


Thanks!
