Would your application work without QT? You need QT+your code to make your application work. You don't need GNU C compiler for your built code to work, you will need GNU C library (glibc). But glibc is under LGPL. If glibc were under GPL, what you say will be correct. I think the confusion is because we are not used to many GPLed libraries and assume libraries can't be GPL. >> > "The Open Source Edition is freely available for the development of Open > Nokia? how did nokia come into the picture? well you found it yourself.

Any application that will need QT to run (compile time or runtime) is a derivative work. Any program that uses a library is a derivative work and your ability to use the library is based onthe license of the library. Well, there is still contention whether dynamic linking can be a derivative work. - Praveen -- പ്രവീണ് അരിമ്പ്രത്തൊടിയില് <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call, if you are unable to speak?
