Hi Selim, did you export operator<< via your LinkDef.h? For friend functions you have to add lines like: #pragma link C++ function operator<<(ostream&,const TRange&); to your LinkDef.h file, since friends are no class member functions they will not be automatically included when TRange is exported. Cheers, Fons.
