[Gate-users] Installation problems - Root related?

[Marc Chamberland]

Thank you for the quick reply, Simon.

The first time I tried making Gate, ROOTSYS was unknowingly set to a  
newer version of Root and the linking process failed miserably.

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  
beforehand):

mchamber at surt> printenv ROOTSYS
/data/data014/HEP/root-5.14
mchamber at surt> printenv LD_LIBRARY_PATH
/data/data014/HEP/root-5.14/lib:/local/X11/lib:/local/X11/lib/X11:/usr/ 
lib:/lib:/usr/lib/X11:/usr/openwin/lib:/local/lib:/opt/local/lib:/data/ 
data014/HEP/Geant4/geant4.9.0.p01/lib/Linux-g++:/data/data014/HEP/ 
CLHEP/lib:/data/data014/HEP/Coin/lib:/home/mchamber/geant4/lib/Linux-g++
mchamber at surt> make

`TTree::SetEntryList(TEntryList*, char const*)'
./tmp/Linux-g++/Gate/libGate.so: undefined reference to

./tmp/Linux-g++/Gate/libGate.so: undefined reference to

make: *** [bin/Linux-g++/Gate] Error 1

You say those functions should be defined in the header file? Would  
that be TTree.h? Or would they be in another header file? Because in  
TTree.h from root 5.14.00g, those functions are definitely not there.  
There's CopyAddresses, but it takes on an additional argument. If you  
have time, please have a look at the attached file. It's from the  
source code of Root 5.14 that I just downloaded from the Root website.

Thank you again for your time, it's really appreciated!
