Dear ROOT team and users,
As a beginner in ROOT and C language, I am trying to debug a root macro. For this purpose I tried to use the debugging platform that have been provided in [root.cern → debuging-root-scripts-in-eclipse]. Unfortunately I can’t proceed with the debugging because building the code is not successful. I am receiving the following errors upon compiling the “analysis.C” :
main.cpp:
#include <TApplication.h>
// TODO: Include your ROOT script below
#include "analysis.C"
int main(int argc, char **argv) {
// Instantiate TApplication
TApplication* app = new TApplication("rootEclipse", &argc, argv);
// TODO: Call your ROOT script entry fiunction
analysis();
// Enter the event loop
app->Run();
// Return success
return 0;
}
analysis.C:
#include <iostream>
#include "TROOT.h"
#include "DNAVolumeType.hh"
#include <fstream>
#include <sstream>
#include <cstdlib>
#include <TCanvas.h>

{
TH1* hist = new TH1D("hist", "hist", 10, 0, 10);
hist->FillRandom("gaus", 10000);

}
and the errors are:
/usr/bin/ld: CMakeFiles/root-eclipse.dir/src/main.cpp.o: in function `Molecule::Molecule(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, int, ThreeVector<double> const&, int)':

analysis.C:55: undefined reference to `ThreeVector<double>::Class()'
Since I am a new user I could not attach the “DNAVolumeType.hh” and the “CMakeList.txt”.
Just in case it could help:
I am using the Geant4-DNA package. The outputs of the example that I am using (dnadamage1) are 2 “.root” files. The final results are obtained using two ROOT macro files: “molecule.C” and “plot.C” through executing:
{
gROOT->ProcessLine(".L molecule.C");
gROOT->ProcessLine(".x plot.C");
}
Now, In order to be able to debug these codes, I am trying to combine “molecule.C” and “plot.C” into one(the “analysis.C”) as a standalone C++ code. I started with bringing the “molecule.C”, where I am encountering the above mentioned errors. If having the “plot.C” or “molecule.C” could help, I can share them with email.
Many thanks in advance,
Cheers,
Ali.
