Hi all
the following code i am using to see sthe spectrums it is worrking fine on FedoraCore5
but on Scientific Linux 5.2 it shows break segmentation which i am mentioning at the end
is there is any missing library in SL5.2
[code]#include<iostream.h>
#include “TTree.h”
#include “TFile.h”
#include “TH1F.h”
#include “TString.h”
#define MAXSAMPLES 200
void treetest2(const char* filename, int card, int channel)
{
TFile myfile = new TFile(filename);
TTree tree = (TTree)myfile->Get(“UnpackxTree”);
TXXXUnpackEvent event= new TXXXUnpackEvent(“input”);
TObjArray* blist = tree->GetListOfBranches();
TBranch* topb= (TBranch*) blist->At(0);
TString topname;
if(topb)
{
topname=topb->GetName();
cout <<"Found top branch "<<topname << endl;
}
tree->SetBranchAddress(topname, &event);
TString hname;
hname.Form(“Card_%d_Channel_%d”,card,channel);
TString htitle;
htitle.Form(“Sum of card %d, channel %d”,card,channel);
TH1F *his = new TH1F(hname, htitle, MAXSAMPLES, 0, MAXSAMPLES);
tree->GetEntries();
for (Int_t i=0;i<1;i++) {
tree->GetEntry(i);
// now take a sample from event structure:
for(int samp=0;samp<MAXSAMPLES;++samp)
{
Short_t value=event->fCards[card]->GetData(channel,samp); // access data from event structure
his->Fill(samp,value);
}
}
his->Draw();
}
[root@localhost Go4Example2Step]# root -l
