Hi,

so, i use a Makefile
i generate the dictionnaries .so, in particular from the main class that contains the main code, using rootcint, with

   gSystem->Load("./checkOQ_cxx.so");
   gSystem->Load("./EnergyRescaler_cxx.so");

   //  to produce checkOQ_C.so : .L checkOQ.C+; to create the checkOQ_C.so
   //.L checkOQ.C+
   // needs to do setup.sh -tag=15.6.9.11,AtlasProduction before

   TChain *mychain_data=new TChain("photon");    mychain_data->Add("/sps/atlas/groups/photons/PhotonD3PD/data/p541/Skimmed/2011/PeriodB/group10.phys-higgs.HSG1.Skim2g20loose_data11_7TeV.00177986.physics_Egamma.merge.NTUP_PHOTON.r2276_p516_p523_p541_v0001.110427183221/*root*");

   gSystem->AddIncludePath("-I/afs/in2p3.fr/home/e/escalier/public/Photon/Common/DataQuality/GoodRunsLists");    gSystem->AddIncludePath("-I/afs/in2p3.fr/home/e/escalier/public/Photon/Common/PhysicsAnalysis/AnalysisCommon/PileupReweighting");

   mychain_data->Process("ComputeInvariantMass.cxx+"); //note the "+"

-->this creates ComputeInvariantMass_cxx.so

maybe : actually i don't understand what is the meaing of "loading the library"

just in case : in my code, i have put :
gSystem->Load("./ComputeInvariantMass_cxx.so");

-->no impact on this warning
