Hi everybody,

I've updated pandaroot today using the howto update tutorial. When I used the run_sim_sttcombi_pgun.C, run_digi_sttcombi.C and run_reco_sttcombi.C macros, I obtained the following error concerning the libDch, but anyway the macros didn't crash and finished normally.

Then I opened the reco_sttcombi.root file. I had the message below and I also could see that the LhePidTrack.GetMomentum() folder disappeared.

I checked the directory /vol0/home2/boucher_loc/soft/buildpanda/lib/ and the libDch.so exist.
For the moment, I comment out in the rootlogon.C file the line:
gSystem->Load("libDch");
and I don't have anymore the error with libDch neither with the reco_sttcombi.root file.


Did someone have this problem before?

Thanks

Jérôme
