    I have defined some classes which are giving a linker error like the one in the subject. could anyone provide some info on the error, I have understood it has something to do with the virtual table but am not able to figure out what. what makes it more harder is that I have not used any virtual functions in the class..

    What i wanted to know was what can cause a error like <class name>::_vtbl (linking error).. I do believe it has something to do with the virtual table but as i had mentioned in my post that I have not used any virtual function, I was unable to understand why am I getting such an error... Although I have inherited from the class ostrstream. could that be the problem?

    cant post the code.. confidentiality issue... the base class is ostrstream class and the derived class does not have a single virtual function..

    Perhaps you can construct a small, similar snippet that fails in the same manner. Failing that, you will need to go to the magician/mind reader forum.
