While doing make command for the RooUnfold, I am getting this error:

$ make

Hello,

This is an error using a package RooUnfold which is not part of ROOT.
I think however the error is caused by using a too old version of ROOT, RooWrapperPdf was introduced in ROOT version 6.20 and you are using a very old version 6.12. The solution is to use a most recent version of ROOT, like the recommended one, 6.28

Thank you so much.
My current ROOT version is 6.24/08. But when i am giving the command ‘cmsenv’ the ROOT version is changed to 6.12. Also, in the newer version, I am getting the error:

It looks like Roounfold is present also in the cms (CMSSW) environment. You should probably use consistent versions, not mixing the two

Got it now.
Thank you.
