This probably means you haven’t provided a definition/implementation for MyEventAction::MyEventAction(MyRunAction*) (and similarly for MySteppingAction::MySteppingAction(MyEventAction*). I.e. you’ve probably only got something like

class MyEventAction ...
{
  public:
   MyEventAction(MyRunAction*); // this is the definition
...
};

and you also need the definition, i.e. the actual body of that function. E.g. in MyEventAction.cc:

MyEventAction::MyEventAction(MyRunAction*)
{
  // code to construct MyEventAction goes here
}
