[Qt-interest] Linker Error I do not understand

[Justus Best]

Hi,

Your pro file looks fine to me, but if I have to fight with such 
problems I would start with the most simple pro file possible so just 
absolut filesystem path, only TEMPLATE = lib and CONFIG += dll and the 
DEFINES you really need. Then compile the lib and check if the fuctions 
get exported. If not the error is in the code, I would look for typos in 
#ifdef's and even try to remove conditional compilation compleatly for 
the moment and just setup the classes for the one case you worry most 
about. If it works then u start adding conditonals again and check if it 
breaks. And maybe check if its a namespace problem, but then they should 
be at least exported.

Hope it helps

Justus
