It is not a definition, but a mere declaration. Use c++filt to demangle the symbol. If you list the libraries you want to link in an order which is incorrect you can get the typeinfo error.

You never call that function statically, but the vtable wants a reference to it because it might be invoked in a dynamic binding context (i.e. The first time I did this I got strange "multiple definitions" errors, so I included the headers of the subclasses in the header of teh superclass, and it started to work.I'm Fno-rtti All done.You will be able to generate the dll.as per my observations this issue encounters sometimes with VC6.0.;) Shiv S.Kushwaha Marked as answer by Shiv S.Kushwaha Monday, August 10, 2009 5:14
