Dear experts,

I am trying to setup Goo Run List cut needed for my analysis. It actually reads the xml file and apply the cut to those events which are good. The xml file and .so file is given by the package Good Run List.

But When I incorporate it to my code as follows, I am getting the error below the code. I want to specify that interactively, I can load .so file using gSystem but in code it is not recognising gSystem as well as DQ flag which I supose is after effect of no loading .so file. Could anyone help what header file or what needs to include in my code.

the code is as follows.

// Setup for Good Runs List

gSystem->Load("$TestArea/DataQuality/GoodRunsLists/i686-slc4-gcc34-opt/libGoodRunsListsLib.so"); DQ::SetXMLFile("data10_7TeV.periodD4.159041-159086_LBSUMM_DetStatus-v03-pass1-analysis-2010D_data_eg_standard_7TeV.xml"); TCut goodRunsList = "DQ::PassRunLB(RunNumber, lbn)"; Int_t nEvents;
nEvents = Chain -> Draw(">>list", goodRunsList); cout << "Number of Events after GRL:\t" << nEvents << "\n" << endl;

And I am getting following error.
