hi Elisabetta,
this is NOT a pattern recognition error in PndTrkTracking2 rather the class
GFAbsTrackRep is missing : as Ralf pointed out, there must be some missing library.

Besides, I checked the Pattern Recognition code again.
It actually returns with no results (== no PndTrackCand-idates) if the TClonesArray of the Mvd MC Points
is missing.
In other words : you have no crash, but you don't get any PndTrackCand-idates.

I have changed one line of code in PndTrkTracking2.cxx and I fixed that. Now one should get PndTrackCand-idates
also when the Mvd are NOT simulated.

In case you need more help, please let know

Cheers ! Gianluigi

Hi Gianluigi,

the error which I get when running the reco_complete.C macro is a bit *cryptical*:

Error in <TClonesArray::SetClass>: called with a null pointer
dlopen error: /home/prencipe/panda/ undefined symbol: _ZTI13GFAbsTrackRep
Load Error: Failed to load Dynamic link library /home/prencipe/panda/
Error in <TCint::AutoLoadCallback>: failure loading dependent library for class PndRecoKalmanTask
Info in (PndGeoHandling::Instance): Making a new instance using the framework.

It is saying that I call a null pointer. then I assume it is because the mvd detector is commented out from the CMakeList.txt. However, up to now, with the mvd code included in the CMakelist.txt of the trunk24275, I don't get even pandaroot compiling....
So, for the time being, I would do the following: just test pandaroot with genfit2, when only the stt detector is active. Do you have any suggestion or/and other better thought?

cheers and thank you, Elisabetta
