TDSet from TChain problem

ROOT
1 
root [0] TChain chain("PAUReco","PAUReco")
root [1] chain.Add("reduced.root")
(Int_t)1
root [2] TDSet *set = new TDSet(&chain, 0)
Error: Can't call TDSet::TDSet(&chain,0) in current scope (tmpfile):1:
Possible candidates are...
(in TDSet)

where am I wrong? Thanks

why do you use “chain” as a reference
TDSet *set = new TDSet(&chain, 0)
if you want to call this one
TDSet::TDSet(const TChain& chain,Bool_t withfriends=kTRUE);
?

Sorry, all my apologies. I’m working too much, I need a break.

No need to be sorry. It happens with everyone :wink:
