Hello everybody, I have tried the new release of ROOT. I am facing some problems I did not have on version 3.03.09. 1.When compiling a routine or a class using TVector3, I obtain the following warning: cxx: Info: /cern/root/include/TMatrix.h, line 343: function "AreCompatible(const TMatrix &, const TMatrix &)" redeclared "inline" after being called inline Bool_t AreCompatible(const TMatrix &im1, const TMatrix &im2) --------------^ 2. When I use a TTreeViewer tu analyse the data in a TTree using a class, the behaviour of the TTree is somewhat erratic: ROOT stops with a segmentation fault a random times. 3. when plotting bidimensional histograms, the "ZCOL" option generates floating point exceptions each time the TPad is updated (after a zoom on one axis or after defining a Graphical Cut). 4. when I use a TSelector (here Exo1) to analyse a TTree (generated with former versions of ROOT, 3.03.09 or 3.02.07), I obtain the following warning: cxx: Warning: /data2/cussol/Jour5/./uaaCHdKIP.cxx, line 61: statement either is unreachable or causes unreachable code Assert(sizeof(::Exo1) == sizeof(ROOT::Shadow::Exo1)); ------^ The TTree I use and the Classes Fragment (not forget to load the libPhysics.so library) and Event are present in the tarball at the following URL: http://caeinfo.in2p3.fr/root/Formation/Jour5.tar.gz I am the only one to face these problems/features? Could it be due to the system I use (TRUE64 on a Dec/Compaq)? I run root v3.04.01 compiled with cxx on a DEC/COMPAQ alpha under TRUE64. Thank you for your help.
