c++ a missing vtable error

Question

I am getting a really weird error related to missing vtable for a given class constructor and destructor. Please help me to resolve this.

Undefined symbols for archi

Ah! Mulling over this I think I get what is happening. I'm betting that CCNode is code which belongs to somebody else.

Any virtual functions you inherit are also virtual in the derived class... and it is common practice to make the destructor virtual... you might not realise the destructor is virtual.

Also if you are using somebody else's header file, but forgot to link to their object file, it might cause this error, as the linker would be missing the destructor of CCNode.
