Following up on this problem, and after another set of debugging sessions, I think that the problem is due to the use of STL classes inside DLL's. In particular the use of STL collections like maps and vectors in Wt.dll . I had this problem before in a different project and I remember that it required to 'export' the definition of these collections in the dll project.
That would explain the type of warnings I am getting when I compile my project: 2>C:\Program Files\WT\include\Wt/WApplication(1395) : warning C4251: 'Wt::WApplication::encodedObjects_' : class 'std::map<_Kty,_Ty>' needs to have dll-interface to be used by clients of class 'Wt::WApplication' If this is the problem, is there any way to workaround it? Maybe I missed a CMAKE switch when I compiled Wt? Or should I refrain from using Wt dll's. If so... what are the other options?
