[AGENT++] No library found

[Samuele]

Hi,
I have successfully generate my own SNMP agent. I have my executable under
/<path-to-agent++>/agentgen/agent/src

When I try to start my agent i get the error message:
error while loading shared libraries: *libagent++.so*: cannot open 
shared object file: No such file or directory

Such a library is in
/<path-to-agent++>/lib. Why this library is not found? I have to say 
that this is my first time with agent++...
Do I miss something? Any help is appreciated.

Thanks in advance,

 Samuele
