Problem loading more than two libraries (rootlogon.C)

Hi everyone

I am trying to use Delphes on MadGraph then I chose to load libDelphes.so with

gSystem->Load(“libDelphes.so”);

on the rootlogon.C. The main problem is that I am also loading libExRootAnalysis.so and noticed it doesn’t works fine. I got the message

Loading SEStyle...
Warning in <TClassTable::Add>: class ExRootTreeReader already in TClassTable
Warning in <TClassTable::Add>: class ExRootTreeBranch already in TClassTable
Warning in <TClassTable::Add>: class ExRootTreeWriter already in TClassTable
Warning in <TClassTable::Add>: class ExRootResult already in TClassTable
Warning in <TClassTable::Add>: class ExRootClassifier already in TClassTable
Warning in <TClassTable::Add>: class ExRootFilter already in TClassTable

Someone knows what is going on?
Thanks!

Observation: It works fine if I try to load just one library, but more than one do
not.


ROOT Version: 5.34/36

Hi,

do you have the same warnings with ROOT6?
This warning is harmless but it’s informing you that the type system is already aware of those classes, i.e. they have probably been selected in two different dictionaries.
