[Qt-interest] LGPL and static linking

this exception file just allows incorporation of
"material from a header file that is part of the Library", 
where 
"material is limited to numerical parameters, data
 structure layouts, accessors, macros, inline functions and
 templates".

well. how else should i write code, which uses the library?

this is true?!
afaik, german law seems to distinct between "uses the lib" and "mainly consists of the lib".
so if your binary uses the lib (dynamically) and won't run without, this may be interpreted as "mainly consists of the lib",
and thus would not be GPL compatible. LGPL makes this possible, by explicitly allowing this, methinks.

i recently was in the same situation, where i had to decide to use GPL code in commercial code, dynamically linked again.
my employer decided not to do this after hearing the not yet solved problems or missing judgments concerning such tasks.
so, my advice would be not to try to get in trouble...

and, another good contact for such a question would be:
