Error Running Root Examples (Error in cling::AutoLoadingVisitor::InsertIntoAutoLoadingState:)

_ROOT Version: I am not sure how to check
_Platform: Linux
_Compiler: Not sure what this is, sorry

Hi all, I am very new to all of this, and so I apologize in advance.
I am working through the guide for madgraph and delphes from the cern wiki: (I tried putting the link here, but the forums won’t let me because I am a new user) Search “Madgraph and Delphes Tutorial”
Everything has been working well, except for when I try to run some Macro-based analysis.

Specifically, when I run

root -l examples/Analyzer1.C'("../ppTOzh_zTOvv_hTOaa_13TeV/Events/run_01/tag_1_delphes_events.root")'

I get errors (can’t upload the document because I am a new user)

Error in cling::AutoLoadingVisitor::InsertIntoAutoLoadingState:
Missing FileEntry for classes/DelphesModule.h
requested to autoload type DelphesModule
Error in cling::AutoLoadingVisitor::InsertIntoAutoLoadingState:
Missing FileEntry for classes/DelphesFactory.h
requested to autoload type DelphesFactory
Error in cling::AutoLoadingVisitor::InsertIntoAutoLoadingState:
Missing FileEntry for classes/SortableObject.h
requested to autoload type SortableObject
… (similar lines)

I was able to find the files that the error messages are looking for, so I think I just need to tell root the necessary file path(s), but I am not sure how to do that.
Any help would be greatly appreciated.

Hi @MaxL,

Please, see the related post Error in cling::AutoloadingVisitor::InsertIntoAutoloadingState: Missing FileEntry for modules/TrackCovariance.h. That should help. :slight_smile:

Cheers,
