Good Morning Genevaaa,..;) Thanks for the help,.. I did what was requested, but not correctly as it seems and would need further assistance,.. My files are as follows: >>> TRange.H ==================================== #ifndef TRange_H #define TRange_H #include <iostream.h> #include "/usr/local/root/include/TObject.h" class TRange : public TObject { public: [...delete...] friend ostream& operator<< (ostream& AStrm, const TRange& ARange) { AStrm << "hello"; return AStrm; } ClassDef(TRange, 1) }; #endif <<< ---------------------------------------------- >>> LinkDef.h ==================================== #ifdef __CINT__ #pragma link off all globals; #pragma link off all classes; #pragma link off all functions; #pragma link C++ class TRange; #pragma link C++ function operator<<(ostream&,const TRange&); #endif <<<------------------------------------------------ >>> Makefile ====================================== [...delete...] LIBNAME1 = TRange DICTNAME1 = $(LIBNAME1)Dict $(LIBNAME1).o: $(LIBNAME1).H $(LIBNAME1).C $(CXX) $(CXXFLAGS) -c $(LIBNAME1).C -o $(LIBNAME1).o $(DICTNAME1).C: $(LIBNAME1).H $(LIBNAME1).C @echo "Generating $(LIBNAME1) dictionary ..." @rm -f $(DICTNAME1).* @rootcint -f $(DICTNAME1).C -c -p $(LIBNAME1).H LinkDef.h <<<------------------------------------------------ I included the -p option after I was requested to do so, but still get the following error message: >>> stdout/err ==================================== Generating TRange dictionary ...
