Hi all,

in the newest trunk (rev 6990) I can't load libEmc.so anymore (see below).

Is this maybe related to the proxy dictionary? (the undefined symbol looks a bit like this).

thanks in advance, Soeren

Yes, I think you have load two additional libraries to solve this error (it was changed in gconfig/rootlogon.C). See the 3rd and 4th posts in this thread.

In the macro you use to load the PandaRoot libraries, PndBase and GlobalTasks have to be added:

...
gSystem->Load("libBase")
gSystem->Load("libPndBase") (<- here to add)
gSystem->Load("libGlobalTasks") (<- here to add)
gSystem->Load("libTrkBase")
...

But the macro tutorial/lhetrack/run_sim_tpccombi_pgun.C is already loading the gconfig/rootlogon.C macro. Is it possible that maybe gconfig was not updated?

Hi,

the problem is simply the rootlogon.C in the tutorial/lhetrack, by default root looks in the current directory for the rootlogon.C and here he find one which does not contain the libraries he need, I remove it from SVN, so it should at least crash somewhere else now (MDT).


regards

Mohammad
