[quote]Regarding your suggestion in my another post ([How to call external libraries , I did not exactly understand what you mean by after ‘actual declaration’? Does it mean including pragma after #include [/quote]I somewhat mis-read your code snipped and guessed (wrong) that fastjet::PseudoJet was declare later in the same file. In that case it looks like all you were missing was the proper #include before the #pragma:[code]#include
#include <iostream.h>
#include
#include “TString.h”
#include “fastjet/PseudoJet.hh”
#include “fastjet/ClusterSequence.hh”
#include “fastjet/Selector.hh”
#ifdef CINT
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ nestedclasses;
#pragma link C++ class fastjet::PseudoJet+;
#pragma link C++ class std::vectorfastjet::PseudoJet+;
#endif
…[/code]
