about gcc -o snmpdemoapp ... -lsnmp

Dear Thomas and Dave:
  when I apply the Makefile supported from
http://www.net-snmp.org/tutorial/tutorial-5/toolkit/demoapp/Makefile

 and execute  make snmpdemoapp, the following error message occurring :


#make snmpdemoapp

cc     snmpdemoapp.c   -o snmpdemoapp

Please use the Makefile we provide:

Or at least use the full set of libraries indicated by
   net-snmp-config --libs
