Troubles with ClassDef and ClassImp

Hi

I am trying to save my class in a TFile. I have read the documentation and I learned that I need to use the ClassDef and ClassImp in my .h and .C files. So far so good.

The trouble is that when I include those lines in my code, then I get an error when I compile my files. I even tried in a simple test file and I've got exactly the same error.

Well, I compile the code within root with the .x MyTest.C++ command

The .h and .C files are attached.

Thanks for your help. Salva
