Hi all.

I've read some docs to understand how to instance a class from a library in
BTW: Linux's lib loading functions are "pure" C functions and, obviously,
dont' understand what's a class... :)))

I hope you all like this simple example of dynamic class loading.

The package contains 3 files:

- main.cpp    (main code: contains the calls to Linux's library loader)
- libgomd.cpp (is the class loaded at runtime)
- lgomd.hpp (an header used by both main.cpp and libgomd.cpp: so the main
app knows what to load!)

How to compile:
- main.cpp:        g++ main.cpp -o testlib.app -ldl
- libgomd.cpp:   g++ libgomd.cpp -o libgomd.so -shared

How to execute
- ./testlib.app [nodeId]

Obviously the two binaries must be in the same directory... :)

I need you comments... :)
