No type named 'DataLoader' in namespace 'TMVA'


I’m trying to execute tmva tutorial code, but at the

TMVA::DataLoader *dataloader=new TMVA::DataLoader("dataset");

this code line, error happens.

no type named 'DataLoader' in namespace 'TMVA'

for using DataLoader, I wrote this line


I used TMVA/DataLoader.h instead, but error again.

Also, I looked at this

but nothing wrong with my root. I’m using ROOT6.

Please read tips for efficient and successful posting and posting code
