>  The problem is that in authenticationmonitor.h:44 you define a std::vector (hey, is this a c++ or qt program ? ;) ) and then export the class. Because of this msvc has to instantiate the whole class including the vector member. But due to the forward declaration it's not possible. See also KDE_FULL_TEMPLATE_EXPORT_INSTANTIATION in kdemacros.h .
