Hi all! I am trying to test out the root tutorial: pythiaExample.C using TPythia8.h instead of TPythia6.h. When I try to load and execute in root prompt it returns:
/path/to/pythia8.C:2:10 fatal error: ‘TPythia8.h’ file not found.
I copied the header to /root-6.26.10-install/include/TPythia8.h
and get a similar error:
/path/to/root-6.26.10-install/include/TPythia8.h:9:10 fatal error: ‘Pythia8/Pythia.h’ file not found.
Seems like I need to add the standalone pythia header to root’s compile path?
Hi, I rebuilt ROOT from source using the instructions in the link you provided. I am still getting the same error and root-config --has-pythia8 is still returning a flat no.
