Hi,
In the FinishTaks() method of class R3BCalifaMapped2CrystalCalPar.cxx (which is a FairTask) I implemented a TSpectrum call in order to find some calibration parameters, such as,
#include <TSpectrum.h>
...
TSpectrum *ss = new TSpectrum(fNumPeaks);
for (Int_t i=0;i<fNumCrystals;i++){
nfound = ss->Search(fh_raw_energy_crystal[i],fSigma,"",fThreshold);
fChannelPeaks = (Double_t*) ss->GetPositionX();
TMath::Sort(nfound, fChannelPeaks, idx, kTRUE);
...
}
When I compile everything is ok. However, when I try to run the macro using the fairtask R3BCalifaMapped2CrystalCalPar, appears the following error:
/home/fpddv1/elisabet.galiana/Escritorio/FairSoft/FairSoft_Install/bin/r oot.exe: symbol lookup error: /home/fpddv1/elisabet.galiana/Escritorio/R3BRoot/R3BRoot_build/lib/libR3 BCalifa.so.SOVERSION: undefined symbol: _ZN9TSpectrumC1Eid
I have checked for another usages of TSpectrum in R3BRoot and I found that in tof/R3BTofdCal2HitPar.cxx it is used but currently commented out.
In addition, I try to solve it by introducing the solution found in the ROOT forum: https://root-forum.cern.ch/t/undefined-symbol-with-tspectrum/24109 but it doesn't work either.
Could you give me some light about it, please?
Many thanks in advance.
