Undefined reference to vtable

Question

When building my C++ program, I\'m getting the error message

undefined reference to \'vtable...

What is the cause of this probl

Answer 1

• Are you sure that CDasherComponent has a body for the destructor? It's definitely not here - the question is if it is in the .cc file.
• From a style perspective, CDasherModule should explicitly define its destructor virtual.
• It looks like CGameModule has an extra } at the end (after the }; // for the class).
• Is CGameModule being linked against the libraries that define CDasherModule and CDasherComponent?
