If you haven't got a commercial license of Qt you can't compile your program with a static linking.

If you haven't got a commercial license of Qt you can't compile your program with a static linking.

Of course you can! Not under the LGPL, but under the terms of GPL it is still possible:

lykurg@XXX:/qt/qtsdk-2009.02/qt$ ./configure -static -release -qt-zlib -qt-gif -qt-libpng -qt-libmng -qt-libjpeg
Which edition of Qt do you want to use ?

Type 'c' if you want to use the Commercial Edition.
Type 'o' if you want to use the Open Source Edition.

o

Download the sources again, maybe you use "commercial" source?

Our wiki is also a good place for getting informations: Building static applications

Wow! So now I'll try the difference between GPL and LGPL.

I've got only a question: if on windows I compile my program with static lybrary using QtCreato (ming32-make), I still also need to add the dll of the compiler?

Wow! So now I'll try the difference between GPL and LGPL.

The most evident different is, that you must publish all sources of your program. And it must be runable even without linking to a proprietary/closed library.

Yes I think so.
