Hi.....

MakeClass() function of a TTree is usually used to produce a class for the given root data file, which is later on compiled in ROOT and run with Loop() function. Similarly a class file, of the ROOT data produced with the CMS software CMSSW (EDM based) is generated along with header file, which is not able to compile within ROOT by giving the following message:

---

Error: class,struct,union or type edm not defined Ijaz.h:294: *** Interpreter error recovered

---

How can i remove this error, either this class is not valid for edm based software or something else?
