Ed,
The problem has nothing to do with TH1I, but with an incomplete declaration
of vector. Choose one of the two solutions:
//solution1
===========
#include <TROOT.h>
#include <TH1.h>
#include <vector>
using namespace std;
class Analysis {
private:
vector<TH1S*>* m_particleLevelsHist;
};
solution2
=========
#include <TROOT.h>
#include <TH1.h>
#include <vector>
class Analysis {
private:
std::vector<TH1S*>* m_particleLevelsHist;
};
