Problem when creating array of histograms ROOT

Try: [code]#include “TFile.h” #include “TH1.h” #include “TString.h” #include “TDirectory.h” #include “TROOT.h” #include std::vector<TH1D*> *myhists(int runfirst, int runlast, int first_segment, int last_segment, int detn) { TDirectory cwd = gDirectory; std::vector<TH1D> hists = new std::vector<TH1D>; // Raw signals // Load File TString f_name = TString::Format(“HPGe_%d_%d_%d.root”,runfirst, runlast, last_segment); TFile *f = TFile::Open(f_name); if ((!f) || (f->IsZombie())) { st…
