Compiling Delphes 3.1.2

[Philipp]

Hi,

when trying to compile Delphes 3.1.2 i get the

modules/PileUpMergerPythia8.cc:25:20: fatal error: Pythia.h: No such file or directory
compilation terminated.

error already reported in two earlier tickets. Unfortunately, the unset PYTHIA8 recipy did not work.

What seems strange to me is that the Delphes 3.0.5 compiles just fine.

Thank for any hints on how to proceed.

Cheers
Philipp

I am having similar problem installing delphes inside of madgraph:
