    Officially, Qt is not distributed statically linked.

    As Luca said, you need to build it yourself, and you can read more about that "here":http://doc.qt.nokia.com/4.6/deployment.html , including specific notes for each platform.

      Thanks. If I use the LGPL version of Qt, can I legally compile my Qt application statically?

        LGPL only allows dynamic linking. You may have to use GPL / commercial version of Qt if static linking is required.

          Does this apply even if my project is open-source?

            Yes. For Free and open source project you can choose to use GPL license.

              Better is not to use LGPL Qt library statically linked.

                  No, GPL is free for use as LGPL. GPL is more restrictive license than LGPL.

                    Yes, both are free for use. The main difference between them is that with the GPL license your application must be GPL too.

                        Read this post: "Qt: Making the right licensing decision":http://blog.qt.nokia.com/2009/11/30/qt-making-the-right-licensing-decision/ and also the comments by Cristy Hamley. A very good differentiation between static and dynamic linking is presented.
