Re: agentx example gives compile errors

Hi,

the declarations for the above functions are in

#include <net-snmp/net-snmp-config.h>
#include <net-snmp/net-snmp-features.h>
#include <net-snmp/net-snmp-includes.h>
#include <net-snmp/agent/net-snmp-agent-includes.h>

which are not included properly ,

it should get automatically with

CFLAGS=-I  `net-snmpf-config --cflags`


check with this command   "net-snmp-config --cflags" on your terminal , and
check the output path with header files


In my case

$net-snmp-config --cflags
    -fno-strict-aliasing -g -O2 -Ulinux -Dlinux=linux  -I. -I/usr/local/include


the header files are in current or in /usr/local/include(these header
files were in /usr/local/include)
