If you did not remove the tmp directory in the Gate directory (it contains
all *.d files (dependency files) created during the compilation) since this
time, I am pretty sure that the problem comes from here. Because in this
case, for the first time the compilation found the declarations in the
TTree.h file (from the newer version of Root), so even if you have now fixed
ROOTSYS to the good directory (5.14), the compilation continues to search
the implementation of the functions in the library corresponding to TTree.h.
But the problem is that in the 5.14 version, those implementation are
certainly in an other header file.

So if you have never removed the tmp directory, do so and launch again the
makefile with the appropriate path and ROOTSYS variable pointing to
the 5.14version of ROOT, the compilation will start again from the
beginning. Else,
this is a strange case ! because ROOT5.14 is appropriate for Gate3.1.2.

Then, I changed ROOTSYS and LD_LIBRARY_PATH to point to the Root 5.14
> installation and I got the error message from my previous message. In
> any case, I've tried it again just to make sure (I source env_gate.csh

There's CopyAddresses, but it takes on an additional argument. If you
