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 ...
Error: Unexpected EOF G__fgetstream():2 FILE:LinkDef.h LINE:4
