There is this 3 dimensional quantity that I want to see, so I decided to use 3D histograms, looked up some examples and wrote what I needed, there’s no problem getting the data in the histograms, but when I try to save them, I get a single message:
Segmentation fault (core dumped)
which isn’t much to go on to fin d out what is the problem.
I stripped my code of everything, and I get the same message:
#include <iostream>
#include "TH3D.h"
#include "TFile.h"
//
using namespace std;
int main()
{
TFile* histos = new TFile("histos.root","recreate");
int r = 1000;
double limit = 10000;
TH3D *hist_leading_position = new TH3D("hist_leading_position", "Position", r, -limit, limit, r, -limit, limit, r, -limit, limit);
hist_leading_position->Fill(0.0,0.0,0.0);
cout<<"This will be printed, no problem so far"<<endl;
histos->cd();
hist_leading_position->Write();
histos->Close();
cout<<"This won't be printed, the problem is in the previous lines"<<endl;
return 0;
}
What is the problem?, what am I missing here?.
Thanks
