problem when using ddd debuger on Linux

I'm trying to use the debugger of Linux ( ddd ) with no success.
I compile all the files with -g option, but that didn't help.

when I try to run the snmpd using the debugger I got the following message:

(gdb) file /home/local_user/net-snmp-5.1.3/agent/.libs/snmpd
(gdb) run

What I should do in order to debug the net-snmp application using ddd ?
