Hello! I was trying to create a RooDataSet with the data from a TChain, but I’m receiving the following error:
Function Import(*ch) is not defined in current scope teste4.C:25:
My code:
{
TChain *ch = new TChain("tree_name");
ch->Add("file*.root");
RooRealVar tofhit_tmax("tofhit_tmax","tofhit_tmax",-100,100);
RooDataSet* ds = new RooDataSet("ds","ds", tofhit_tmax,Import(*ch));
}
I tried using the “using namespace RooFit”, but I received a more weird error (I checked and all the libraries are at root/lib):

Does anyone know why I am receiving this? Am I doing some mistake in the declaration of RooDataSet?
