Hello, I have an issue with TMVA. While I am running TMVAClassification.C in the guide, I got this error.

Since I am a rookie, does anyone know what to do?

Your variables.C macro is using something (likely TMVAGlob) that ROOT doesn’t know about. That’s probably due to a missing include or source file.

Even though it might not have anything to do with your question: Are you using the TMVA version from SourceForge? Can’t you use the TMVA included in ROOT?
