I create a very simple class:
class TCoord : public TObject {
public:
TCoord();
Float_t& x() {return pos[0];};
Float_t& y() {return pos[1];};
Float_t& z() {return pos[2];};
ClassDef(TCoord,1)
private:
TArrayF pos;
};
With this implementation:
ClassImp(TCoord)
//_______________________________________________________________________
TCoord::TCoord()
{
/////////////////////////////////////////////////////////////////////////
// Constructor
/////////////////////////////////////////////////////////////////////////
pos.Set(3);
}
But I get this link error:
Linking ...
/bin/ld: Unsatisfied symbols:
TCoord::ShowMembers(TMemberInspector&,char*) (code)
Virtual table for class 'TCoord': first non-inline virtual function
in 'TCoord' is not defined. (1930)
How may I solve this problem an why I get this error ?
do I need to derive TCoord from TOject ?
Thank you.
