Open file .root

Ideas and Requirements

Hi everyone , I have Geant4 on ubuntu and I am trying to open the file scoring.root from example B3a. I write on terminal : “root -l filename.root” but I don’t know how to proceed after this . Thank you so much in advance

Try using the browser first (“root [1] Tbrowser browser1;”)?

More a question for the root forums though.

Thank you so much for your reply, I’ll try to do this.

Or just type

.ls

in ROOT session.

Hello I tried this suggestion , but terminal gives back this message:

‘‘IncrementalExecutor::executeFunction: symbol ‘_ZN5cling7runtime8internal9EvaluateTIvEET_PNS1_15DynamicExprInfoEPN5clang11DeclContextE’ unresolved while linking [cling interface function]!
You are probably missing the definition of void cling::runtime::internal::EvaluateT(cling::runtime::internal::DynamicExprInfo*, clang::DeclContext*)
Maybe you need to load the corresponding shared library?’’
Does someone know how to fix the error?
Thank you in advance

First of all, it seems like a ROOT problem, not Geant4. Second of all

what suggestion exactly: TBrowser or .ls. In either case it’s very strange that ROOT interpreter reacts in this way on such simple operation. Are you sure you installed ROOT correctly. One more time, it is a ROOT problem. Would be better to ask on ROOT forum.
