Hello @bellenot…you are right, because I did a mistake to upload the log file…I upladed the file related to the HepMC building instead of the one releated to the installation (moreover, I deleted the log file, so I don’t have it anymore to show you)
…anyway, when I install HepMC using the ROOTIO option, it dowsn’t install anything and the HepMC-install directory is empty. I tried to install without the ROOTIO option and it looks like that it could install it, because there are directories in the HepMC-install directory
Unfortunately, running the Geant4 simulation, it looks like that CMAKE can’t find the HepMC
I know that it’s related to Geant4, but given that the error is from CMAKE, maybe do you know hot to set the HepMC-install path in CMAKE?
