mg5amc_py8_interface

Asked by Christina Karagianni on 2018-11-07

Hello,

after the appearance of this message

    A Pythia8 path is specified via the option 'pythia8_path' but no path for option
    'mg5amc_py8_interface_path' is specified. This means that Pythia8 cannot be used
    leading order simulations with MadEvent.
    Consider installing the MG5_aMC-PY8 interface with the following command:
     MG5_aMC>install mg5amc_py8_interface

I am trying to download mg5amc_py8_interface but this error message appears

MG5_aMC>install mg5amc_py8_interface

HI,

Looks like the path that you specify for PY8 is not valid.
At least if does not find the file:
/home/christina/Programs/pythia8235/share/Pythia8/examples/Makefile.inc

Cheers,

Olivier

Thanks Olivier Mattelaer, that solved my question.
