Problems with PandaRootCharmoniumTutorial

description: Hi, After PandaRoot installation I tried as a first step to run the PandaRootCharmoniumTutorial. I am getting the following error messages both with the trunk and the stable version. After root run_sim_tpccombi.C I immediately get: dlopen error: /home/kph446/fairroot/build_stable/lib/libRho.so: undefined symbol: _ZN19VAbsVertexAlgorithm15theDefaultAlgIdE Load Error: Failed to load Dynamic link library /home/kph446/fairroot/build_stable/lib/libRho.so (int)(-1) *** Interpreter error recovered *** Then, after a work-around by Tobias (modification of rho/Rho_LinkDef.h and rho/CMakeLists.txt): and after root run_sim_tpccombi.C root run_digi_tpccombi.C root run_reco_tpccombi.C root run_pid_tpccombi.C root run_ana_tpccombi.C crashes with: TRho::GetPDG: Instantiating TDatabasePDG from /home/kph446/fairroot/pandaroot_stable/rho/RhoParameters/PDT/evt.pdl Error in <TTree::SetBranchStatus>: unknown branch -> PidChargedProbability Error in <TTree::SetBranchStatus>: unknown branch -> PidNeutralProbability Error in <TTree::SetBranchStatus>: unknown branch -> PndMcTracks Error in <TTree::SetBranchStatus>: unknown branch -> PndEventSummary *** Break *** segmentation violation =========================================================== There was a crash.

description: Hi Albrecht, I just tried with a freshly compiled /trunk (rev. 10205) and it works fine (at least on SL5). By the way, this error can be ignored. Error in <TTree::SetBranchStatus>: unknown branch -> PidChargedProbability Error in <TTree::SetBranchStatus>: unknown branch -> PidNeutralProbability Error in <TTree::SetBranchStatus>: unknown branch -> PndMcTracks Error in <TTree::SetBranchStatus>: unknown branch -> PndEventSummary It comes from the PndEventReader, i.e. it checks which branches are there and which are not, and as far as I understand from Klaus there is no easy way to do this without generating an error. But if the branches are not found, it is no problem (in other words, the macro is not trying to access these branches). Anyway, which system are using? (maybe the PndEventReader has a problem with 64 bit) cheers, Soeren

description: Hi, I have tried to run 500 events at GSI, using lenny 64bit machines, and I had no problems. Probably your crash is connected to the "trunk" external packages that you are using, and not the standard "jan10" ones (or at least this seems to us after a discussion on your problem at the EVO meeting of this morning).

description: another check. fresh op system, fresh external packages, fresh pandaroot trunk. trunk rev. 10249 on suse 11.2 with jan10 external packages (just re-compiled from the tar file distribution) so root 5.26 (AMD64, but only 32 bit installation this time). -> also fine!! this means: with one scientific linux, debian and suse positive report, it probably seems the best option for a tutorial (at least no urgent indication to flag it "infunctional" in the wiki).
