Impossible linker error?

Damn me. Obviously yes. I actually get this exact error message in a bigger (way more complex project) and tried to reproduce the buggy behavior in a simpler sample.It works fine after I added the missing library.

I guess I will have to keep looking for the real problem in my complex library... Anyway, this question is solved. Thank you very much. – ereOn Oct 11 at 15:05.

You can't link just main. O without derived. O as well.

Unless the first virtual function (or first function for a class with no direction virtual functions) is linked in, the vtable won't be linked in.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
