Hello Philippe,

  The problem was related to the $LD_LIBRARY_PATH settings, I didn't clean it before assigning the new libs:

  arne_at_m011-arnevdb RMD_ANA]$ echo $LD_LIBRARY_PATH /home/products/ROOT/new/lib/root:/home/arne/root/macros:/home/products/root/root_v5.24.00/lib/:/home/arne/root/macros:

[arne_at_m011-arnevdb RMD_ANA]$ ./readdata_deb -f testt.txt Reading file :: testt.txt
  found 1000 points
1000 Tree entries
0 Ntuple entries

-------> EMPTY Ntuple !!!

[arne_at_m011-arnevdb RMD_ANA]$ LD_LIBRARY_PATH=""
[arne_at_m011-arnevdb RMD_ANA]$ source /home/products/set_env.sh
[arne_at_m011-arnevdb RMD_ANA]$ echo $LD_LIBRARY_PATH

/home/products/root/root_v5.24.00/lib/:/home/arne/root/macros: [arne_at_m011-arnevdb RMD_ANA]$ ./readdata_deb -f testt.txt Reading file :: testt.txt
  found 1000 points
1000 Tree entries
1000 Ntuple entries

-----> 1000 Entries :-D !!!!!

Thanks for your help !

  Arne.
