First I'd like to beg a pardon since I am not the author of that
code but Rene Brun and my name is mentioned there by mistake.

This example is NOT a macro. It is a piece of the STAND-ALONE code
to be compiled with the native compiler and run with no extra ROOT
executable.
This explains the message you got. An interactive ROOT includes all
ROOT classes pre-compiled. This means one needs no extra "include" to
define any ROOT class to use it. These include statements must be
supplied for the "native" compiler only to create "stand-alone"
application (it is useful for the batch processing for example)

The working example of "how to manage the user defined tree" can be
found under "test" subdirectory of the ROOT destribution kit.
You may find in there:
1. Makefile to create:
1.1. stand_alone code
1.2. share library to be used within a "normal" ROOT session
2. Several ROOT macros. All of them assume the "Event" share
library with ROOT dictionary has been created / loaded(see
above)
Please, look this "test" sub-directory up. Very likely it
answers your questions.
With my best regards,
Valery
