Multiple function definition with gROOT.ProcessLine()

[Wile_E_Coyote]

Std::any in c++17 in ROOT and pyROOT

Try: ROOT.gROOT.ProcessLine('#include <any>') or: ROOT.gInterpreter.ProcessLine('#include <any>') or (better?): ROOT.gInterpreter.Declare('#include <any>') @Axel What is actually the best way to deal with it? Via “gROOT” or “gInterpreter”? Using “ProcessLine” or “ProcessLineSynch” or “Declare”?
