Error: 'Fill' is a private member of 'TProfile'

[clemahieu]

Hello,

I am using RooUnfold on lxplus7 and to do so I use a specific source command:

source /cvmfs/sft.cern.ch/lcg/views/LCG_100/x86_64-centos7-gcc10-opt/setup.sh
source build/setup.sh

In the same code, I try to fill a TProfile histogram:

TProfile *h_profV2_5_gen  = new TProfile("h_profV2_5_gen","Profile v2 5 gen",5,0,40,-1,1);
h_profV2_5_gen->Fill(cos_2phi_gen);

And I get the error:
In file included from input_line_8:1:
/afs/cern.ch/user/c/clemahie/Unfold2/RooUnfold/examples/test4_fit_eff.cxx:293:23: error: ‘Fill’ is a private member of ‘TProfile’

Int_t Fill(Double_t) { MayNotUse(“Fill(Double_t)”); return -1;}

I haven’t gotten this error before with TProfiles, so I assume this is specific to the ROOT setup I’m using. Is there a way around this?

Thanks,
Cole

Try TProfile::FIll(x,y), with y=1 (i.e. adding 1 event, without weight, at that bin); see other Fill methods for v.6.24 on the linked page; the one you used, Fill(x), is listed but if you see the code by clicking on the link at “Definition at line…”, it just sends the message you get.

h_profV2_5_gen->Fill(cos_2phi_gen, 1);
