Warning in <TClass::TClass>

Hello, everybody!

I have a .root file and when I run it, I get these errors:

Warning in TClass::TClass: no dictionary for class TRootLHEFEvent is available
Warning in TClass::TClass: no dictionary for class TRootWeight is available
Warning in TClass::TClass: no dictionary for class TRootLHEFParticle is available
Warning in TClass::TClass: no dictionary for class TSortableObject is available

I’d appreciate it if anyone could help me to resolve it.
I use ROOT_v5.34.38 on Windows 7.

Thank you in advance.

As it seems on windows maybe @bellenot can help ?

Nothing to do with Windows, it’s just because you don’t have dictionaries (libraries) for the classes stored in the root file. I think you can ignore those warnings. Otherwise, you will need the libraries used to produce the original data

Thank you very much. So I don’t need those libraries to read the events?

It depends, but I guess that at the end, there should be only simple types…

Ok, thanks again.
