TRolke Class on windows vista

I just installed ROOT 5.22 on windows vista, and tried running the Rolke.C tutorial, here’s what i got:

Error: Can’t call TRolke::SetPoissonBinomEff(x,y,z,tau,m) in current scope C:\root\macros\Rolke.C(67)
Possible candidates are…
(in TRolke)
*** Interpreter error recovered ***

Does anyone know what’s wrong with my installation? Thanks a lot.


it looks to me you are using a new version of the tutorial with the old version of TRolke (from ROOT 5.22).
Either update your root installation to 5.24 or use the old tutorial version
that you can get from: … sion=26659
