Re: Pythia8 with ROOT V5.27.02

There is a problem in the standard distribution of pythia8135. The installation is problematic on 64 bits platforms, in particular macosx64. If you install on these platforms, you have to modify the config.mk file as follow and configure with

   ./configure --enable-shared

SHELL = /bin/sh
