Especially for this task you __should__ absolutely use ROOT 4 (and preferable 4.04/02) because ROOT 3 had a much inferior way of dealing with Foreigh Classes (unrelated to your problem).

As far as your problem is concerned, it is extremely likely that it has been fixed in recent version of ROOT. However if you try ROOT 4.04/02 and still have the problem please send me how to reproduce it.

Cheers,
Philippe.

Subject: [ROOT] error in running a ROOT based code

Dear ROOTers,

while implementing a modification of ExRootAnalysis, that is a tool devoted to the conversion from ORCA-like data into ROOT TTrees, I met the following error messages:

Error in <TClass::New>: cannot create object of class TRootCalibObj Error in <TBranchElement::GetDataMemberOffset>: obsolete call with (TRootCalibObj,.fUniqueID)

Error in <TBranchElement::GetDataMemberOffset>: obsolete call with (TRootCalibObj,.fBits)

Error in <TClass::New>: cannot create object of class TRootMCEle Error in <TBranchElement::GetDataMemberOffset>: obsolete call with (TRootMCEle,.fUniqueID)

Error in <TBranchElement::GetDataMemberOffset>: obsolete call with (TRootMCEle,.fBits)

The ROOT distribution that I am using is the one related to the variable:

setenv ROOTCORE_BASE /afs/cern.ch/cms/external/lcg/external/root/ 3.10.02/slc3_ia32_gcc323

Does anybody have any suggestions that can help me solving or understanding this error?

Thank you very much,

kind regards
