Hello forum,
I’ve a problem! Up to yesterday I’d used a RedHat 7 version of operative system and the ROOT 4.04 version. Yesterday I moved to a Scientific Linux and a ROOT 5.10 version.
I have a code (it reads a TTree and fill some histograms), which works well on ROOT 4.04, but we I try to execute it on ROOT 5.10 I get these error messagges:
Warning in :
The StreamerInfo of class TTree read from file /yp/dsnuclex1_home3/nuclex/ntuple_05/fast_c5_6_6073_6080.r

has the same version (=15) as the active class but a different checksum.
You should update the version to ClassDef(TTree,16).
Do not try to write objects with the current class definition,
the files will not be readable.

I’m not able to understand what is the problem (the compilation of the code works well in both cases, I get these messages when I execute the code)…
How can I solve it?
Thank you for your help,
Paola
