Hi Daniel,
This message is printed when you connect a TFile containing classes
for which the corresponding shared lib is missing in the running executable.
In your case, the file contains a class MEvenement and you are running
without this class.
This is not a problem if you do not use the class in your scripts.
If you have used the split mode, the TBrowser and TTree::Draw will even be able
to operate on the data members of this class.
If you have lost the original lib containing this class, you can generate
the code of the data part of the class with
myfile->MakeProject("xx","*","recreate++");
This will automatically generate a sub-directory "xx" containing all the header
files for the classes in your file for which the library is missing. It will
also
compile the generated classes, make a shared lib and will link it in memory.
