Re: Using ROOT for Histogramms in Pythia8

Hi Wajid,

this patch to Pythia8 should get you going. Torbjörn told me that we should expect it to end up in the next Pythia8 version.

Cheers, Axel.

The example in /root/root/tutorial/pythia8.C is working perfectly fine. What I am trying to do is execute the /pythia8145/rootexample/goex1. When I execute this script I end up with the following error. Is there any shared file missing I guess.
