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

The GCC FAQ has an entry on it:

The solution is to ensure that all virtual methods that are not pure are defined. Note that a destructor must be defined even if it is declared pure-virtual [class.dtor]/7.

Therefore, you need to provide a definition for the virtual destructor:

virtual ~CDasherModule()
{ };
