DelphesPythia8 with Pythia 8.226

[apdf]

I could previously make and use DelphesPythia8 (in both Delphes-3.4.0 and Delphes-3.4.1) with an older version of pythia (8.219). However, I had to update to a newer version of pythia (8.226). Now when I try to make DelphesPythia8, by running:

make HAS_PYTHIA8=true DelphesPythia8

I get the following errors:

I also double checked that I could get this to work with pythia8219 and that I could use my install of pythia8226 separately from Delphes. I can't seem to track down what's causing this, any help would be appreciated. Thanks!

I've just tried to build Delphes with Pythia 8.226 and it worked.

Could you try to rebuild Delphes with the following commands?

make HAS_PYTHIA8=true distclean
make HAS_PYTHIA8=true DelphesPythia8

Hi Pavel,

Apologies for the slow reply. I tried making DelphesPythia8 on my local machine and that worked fine. The problem is only isolated to making on the server I am using. So I believe my original problem has nothing to do with Delphes, but more than likely is something wrong with my setup there. I'm sure I can figure that out, now that we've isolated the problem.

Thanks!

Hi,

Just curious how you fixed this on your server? I'm seeing the exact same error with Delphes 3.4.1 and pythia8243 (and it was also working previously for me with pythia8219).

Thanks,
David
