I tried to shower events for the NLO process p p > t t~ [QCD].
But I am getting the following error.

Does anyone know what could be happening?
Thanks

I am experiencing the same issues when simply compiling pythia with HepMC2 and including in a main.

Have you perhaps been able to solve it?

Hi aMC@NLO team, same problem here! Pythia8 showering works just fine when I do LO generation using the same model files.

Thanks for the tip Shilpa, but I do have all the extrapaths set, but still pythia8 doesn't compile in with aMCaNLO :*
