Hi Belen, It looks like you are mixing two versions of gcc: you seem be using 2.95 but your ROOT lib path points to 2.96 . You should check your environment variable LD_LIBRARY_PATH and make sure that you have the following path /afs/cern.ch/sw/root/v3.05.05/rh73_gcc2952/root/lib in there (instead of /afs/cern.ch/sw/root/v3.05.05/rh73_gcc296/root/lib). Cheers, Gerri ps: you may find detailed instructions about setting LD_LIBRARY_PATH at http://root.cern.ch/root/Install.html On Tue, 9 Mar 2004, Belen Salvachua Ferrando wrote: > Hello, > > I have been the whole afternoon with a problem and I am not able to > localize the solution.
