I've posted this on other forums, but the common misunderstanding is that static linking is prohibited under the terms of the LGPL, it is not.
Section 6a provides a provision which allows static linking provided that the developer provides (binary) object code, or an offer to do so for a period of 3 years, which may be re-linked with the LGPL components.
Regarding app bundle signing restrictions, these are prohibited by the GPL, but the LGPL allows you to distribute under "...terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications."
If those terms comply with 6a, i.e. that you provide access to unsigned object code in a form which may be relinked, modified for the users own use etc., then there doesn't seem to be a conflict.
6b specifies dynamic linking, but it is only one option in section 6.
Whether 'permitting modification' refers to the actual app bundle, or the components provided under 6a is to my mind an open question. If it were so, then 6a would be invalid regardless. The prerequisites for doing so would be an apple developer account and apple's tools / hardware etc, but under the terms of the LGPL and GPL, the developer is not required to provide these.
[quote author="jdbastardy" date="1284456113"]I liked it so much... I just want to use it for Symbian and Windows development. However. I do not know how to use it with symbian.[/quote]
You can install "Qt: Framework Only":http://qt.nokia.com/downloads/windows-cpp and then Nokia Qt SDK and in the QtCreator add path to Qt: Framework Only directory.
I've got this book. It is great! So many advanced topics in one book! And it is not a problem to read the code snippets. They are tiny and are typed with another font.
I haven't started reading the book but it seems to me that it is based on the author's practical experience. I wonder what other sources of practical experience exist on the Internet. Maybe there is a blog which describes solutions of practical problems with Qt.
Denis Kormalev, Target audience of this book - beginners in Qt for Symbian who want to make his first steps in mobile software development.
iddqd, If I remember correctly, book doesn't contain any info regarding QtCreator.
