Hi, I’ve been trying to execute the example code pythia8.c from the ROOT manual, but I can’t make it work, it shows me this:
root [0] .x pythia8.c
PYTHIA Error in Settings::flag: unknown key Tune:preferLHAPDF
PYTHIA Abort from Pythia::Pythia: unmatched version numbers : in code 8.186 but in XML 8.307

It seems like I’m supposed to install HEB-MC, or LHAPDF, but I don’t know how to do that, I’m still a newbie. Can someone help me, please?
