Hi, everyone
I am writing the trap receiver on manager, based on the net-snmp source code
(apps/snmptrapd.c), i just modified some code, and compiled, then there are
something wrong,

I think there are some function library(.a or .so) to be linked bu I tried

what is wrong? what is the reason?
Thanks very much~!
