Hello,

I'm trying to install pythia from mg5 with 'install pythia-pgs', here is the mg5 debug file (already have g++, gcc and gfortran). Thanks in advance.

Hi,

The first advice would be to NOT install pythia-pgs package this package is fully outdated both in term of code but also in term of physics.
The author of the associated package do not provide support for such tools (for PGS) or that version of the tools (for pythia6) since at least 10 years.

You can install pythia8 via "install pythia8" and Delphes via "install Delphes" command.

If you really want to install pythia-pgs, you will need to wait 2.9.2 where that particular bug is fixed.
But do remember that pythia-pgs is not compatible with modern compiler (gcc needs to be below version 8)

Cheers,

Olivier

Hello Olivier,

thank you a lot, had no idea about those issues regarding pythia-pgs. Installed pythia8 with no problem.
