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.
