Hi all, First of all, sorry for bothering.
I’m trying to hook a function into compiled objects:. I have a hook_class:
#ifndef libstat_hook_h
#define libstat_hook_h
//#include "TH1F.h"
using namespace std;
class libstat_hook{
public:
libstat_hook()
{
};
virtual ~libstat_hook()
{};
virtual bool include(double cdata=0,double csm=0,double sigma=0, /*const TH1F* const hData=0,*/ int range_low=0, int range_up=0)
{
//Write your function here
//Example:
return true;
//your function
}
};
I have two compiled libraries , compiled to .SO. Both have #include “libstat_hook.h”.
Now I’m trying to run a root program.
#include "../Libraries/libstat_hook.h"
/*
class select: public libstat_hook
{
public:
select()
{
};
virtual ~select()
{
};
bool include(double cdata,double csm,double sigma, int range_low, int range_up)
{
cout<<"overwrite"<<endl;
return cdata>=csm;
};
};
*/
void test_only_statistic(TString number="1", TString stream="All")
{
//TString stream="Muon";
TString variable = "_all_minv";
//TString variable ="_MET";
TString suffix="_"+number;
//gSystem->Load("../Libraries/binning2_C.so");
gSystem->Load("../Libraries/libstat_C.so");
gSystem->Load("../Libraries/only_statistic_C.so");
TString dir="/scratch/jvamen/Output/Toys_test/no_signal/minv";
TFile* Toy=new TFile("/scratch/jvamen/Output/Toys_test/no_signal/minv/Toys_"+stream+suffix+".root");
libstat_hook* a = new libstat_hook();
// libstat_hook a;
//cout<<a->include(9,10,10)<<endl; //This works
statistic t(2);
t.insert_hook(a); //this doesn't
t.setOutputFileName("Statistic_"+stream+suffix);
//t.setOutputDirectory(dir);
t.setOutputDirectory(".");
t.setStream(stream);
t.get_toy_file(Toy);
t.findDataTopologies(variable, "../topo/topolist_mc_"+stream+".txt");
t.Calculate_all_pvalues(variable+suffix);
//t.pvalue(topo,variable+suff ix);
exit();
}The code then crashes in these lines:
void statistic::insert_hook(libstat_hook* input_hook)
{
cout<<input_hook<<endl;
if(input_hook->include(1,10,10)) cout<<"true"<<endl;
else cout<<"false"<<endl;
getchar();
stat->insert_hook(input_hook);
cout<<"Inserted hook"<<endl;
}With these errors:

This is even without handing a custom hook routine, why does this crash? It is just an allocated object that should always return true anyway? I can’t figure it out.
