Hi everyone,
I have a problem with all my .C codes with int main() when I try to execute them with the root -l command. Indeed, when I do this, I obtain :
alo@MacBook-Pro TMVA_TEST_Run1 % root -l MergeNTuplesForTraining.C
root [0]
Processing MergeNTuplesForTraining.C...
input_line_9:2:2: error: no matching function for call to 'MergeNTuplesForTraining'
MergeNTuplesForTraining() /* .x tries to invoke function `MergeNTuplesForTraining` */
^~~~~~~~~~~~~~~~~~~~~~~
/Users/alo/Documents/STAGE_M2.nosync/Root_stage_M2/TMVA_TEST_Run1/MergeNTuplesForTraining.C:16:5: note: candidate function not viable: requires at least 2 arguments, but 0 were provided
int MergeNTuplesForTraining(std::string OutputFileName, std::vector<std::pair<std::string, std::string>> InputFilenames, uint MaxEv = -1)
^
My code is like :
int MergeNTuplesForTraining(std::string OutputFileName, std::vector<std::pair<std::string, std::string>> InputFilenames, uint MaxEv = -1) {
// My function
}
int main() {
std::vector<std::pair<std::string, std::string>> SignalForTraining_Up_Vec;
SignalForTraining_Up_Vec.emplace_back(std::make_pair("/Users/alo/Documents/STAGE_M2.nosync/Root_stage_M2/TMVA_TEST_Run1/Tuples/Signal/DTT_13512010_Bs_Kmunu_DecProdCut_Up_Py8_MC12.root","Bs2KmuNuTuple"));
MergeNTuplesForTraining("DataForTraining/SignalForTraining_Up.root", {SignalForTraining_Up_Vec});
}
And I obtain this with all my codes.
But, if I do the following thing :
alo@MacBook-Pro TMVA_TEST_Run1 % root

Everything is working ! Can you help me with that ? Thanks !
