Dear Enrico,
I can send you a small working example, based on the example from FLUKA
site, with Makefile how to compile and link FLUKA object files and
ROOT/С++ object files. I don't use classes derived from TObject, so if
you are going to use standard ROOT classes and objects, it might be helpful.
I'm using ROOT-6.08.06 and GCC 8.2.0 multilib.
Best regards,
Mikhail
