Question

I have the following structure:

class A{
public:
    virtual void fn() = 0;
} ;

class B : public A{
public:
    virtual void fn(){
       //implB
    }
} ;

class Base{
     //whatever
} ;

class C : public Base,public B{
public:
    virtual void fn(){
        //implC
    }
} ;

B* instance = new C();
(*instance).fn()

This seems to call implB and not implC. Is this normal?
I’d like to call implementation implC of fn, is there a way to do it?

You’re right, C::fn() is called when my example is ran alone. My problem actually was that I was dynamically loading this class (C) with ros:pluginlib (http://ros.org/wiki/pluginlib) so the multiple inheritance issue is probably coming from there. That’s a completly different issue I’ll have to look into.
