Error in Delphes' ExRootAnalysis

[Amin Abou Ibrahim]

Dear Delphes developers,

I have been having issues with ROOT 6 and after fixing some errors it boiled down to an error in ExRootAnalysis. I have this question posted on the ROOT forum but then I figured it might be Delphes-specific so I am posting it here as well.
I am running Example2.C on my ROOT file and it works perfectly as long as I am in the Delphes directory. If I run it outside the directory I get an error, but this doesn't prevent the histograms from being generated. I have my LD_LIBRARY_PATH set to Delphes-3.4.0. The errors I get are:

Error in cling::AutoloadingVisitor::InsertIntoAutoloadingState:

Any idea what's going on?
Thanks a lot.

I think that the following commands should be somehow added to Example2.C when running it outside the Delphes directory:

.include <path_to_delphes>
.include <path_to_delphes>/external
gSystem->Load("<path_to_delphes>/libDelphes");

Hi Pavel,

I have those lines added in the script along with gSystem->Load("libDelphes"):
#include "external/ExRootAnalysis/ExRootTreeReader.h"
#include "external/ExRootAnalysis/ExRootResult.h

Also, PATH to Delphes is defined in my .profile. This is still not working.
I attached Example2.C so you can have a look at it if it helps locate the problem.

Thanks a lot.

I've just tested that the following works:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path_to_delphes>

# start ROOT
root -l

# run Delphes example from the ROOT command line
.include <path_to_delphes>
.include <path_to_delphes>/external
.L <path_to_delphes>/examples/Example2.C
Example2("delphes_output.root")

Thanks Pavel.
I tried this from the command line and it works. But I want to have those lines in my script and this where #include "path_to_delphes" is not working. Have you tried doing this?
I'm sorry for the trouble and thanks again.

Best,
Amin

No, I don't have any idea how to do it. Hopefully, you'll have a solution via the ROOT forum.
