Hi, I've developed an Application with GPL'd Qt and Visual Studio Express 2005 under Windows. Can I distribute my source files with the program (exe file) and the binary Qt library files (DLLs)? If not, can I distribute my program statically linked against Qt? Greetings, Thorsten. -- [ signature omitted ]

But only the release version of the Microsoft libs, are allowed to distributed. So as an result you can distribute only the release version of the Qt dll's. The same with static linking.

Not only you can, but you have to.
If your program is linked to the open source Qt libraries, you have to
make the sources of your program available together with the executable.

Just to make it clear: I can redistribute the binary Qt-DLL files of the
GPL'd Edition, right?

Yes, you can:
a) you did not modify the Qt sources (only your own): you can distribute all
involved binaries and MUST distribute your own sources along with them. You
have to give the users a link to where they can find Qt (usually in the
README file or about dialog).
b) you modified Qt: you can distribute all binaries. You also MUST
distribute your own source plus either the modifications you made to Qt
(plus a link to the original) or the full modified Qt source.
In short: the user MUST have the possibility to recompile and relink
everything that is under GPL (that is Qt and your program based on it).

Yes, but only the release one, because the debug one depends on the
debugs libs of Microsoft witch you can't distribute. So you can
distribute the debug DLL's of Qt, but nobody can use it, until he has VC
2005(Express) also.
