Hi, As you said, if your files are really in the following directory "/opt/cern/root-5.14/include/root", Gate will probably search its in this directory "/opt/cern/root-5.14/include", so I think you just have to put them in. And the environment variable LD_LIBRARY_PATH is only for librairies and not for headers. Hope it works.

But unfortunately this is not the reason of the problem. I added $ROOTSYS/include/root/ to my /:$LD_LIBRARY_PATH, but the error messages still exist when running "make". -----Ursprüngliche Nachricht----- Von: yannick grondin [mailto:<a href="mailto:yannick.grondin@imag.fr">yannick.grondin@imag.fr</a>] Gesendet: Freitag, 6.
