Re: guitest

Patrick,

As indicated in the documentation of guitest.C, use

   root > .x guitest.C And you execute via the CINT interpreter)    root > .x guitest.C+ (and you use the natice compiler via ACLIC)

If you insist using your own main program, add #include <TClass.h> at the top of the file.
I have added it in the SVN trunk.
We systematically recommend to go away from "my main program syndrom", in particular with programs having a GUI. It is so much simpler to simply do ".x myscript.C+" ::)
