Agent++-4.6.1 cannot compile with SNMP++-3.5.2

SNMP++/AGENT++
1

Hi,

I could make SNMP+±3.5.2 sucessful. However, I could not cmake Agent+±4.6.1 using libsnmp++ of SNMP+±3.5.2. There are some compiled errors for examples such as #error “_SNMPv3 must be defined in order to use the ProxyForwarder”, ‘class Agentpp::RequestList’ has no member named ‘get_v3mp’, ‘class Agentpp::Mib’ has no member named ‘register_proxy’, … , etc. Therefore, I have to modify CMakeLists.txt to turn OFF the OPTION_EXAMPLES to help Agent+±4.6.1 to compile.

Note: I only saw ‘get_mpv3()’ in SNMP+±3.5.2. However, Agent+±4.6.1 src\snmp_pp_ext.cpp used ‘get_mpv3()’ and agenpro/examples/other src used ‘get_v3mp()’.

Please advise.
Thanks,
Phuoc.

Hi Phuoc,
You need to use the same compiler settings for SNMP++ and AGENT++.
You should activate SNMPV3, even if you would like to use the unsafe SNMPv2c or v1 later too.
Best regards,

Hi Frank,

Thanks for the reply.
I used the same compiler identification GNU 8.5.0
How can I activate SNMPV3?

Thanks,
Phuoc

Hi,

I could active SNMPV3 and compile both SNMP+±3.5.2 and Agent +±4.6.1. However, when I tried to run multi_agent/src/./agent, I got “Segmentation fault, aborting.” Do you have any ideas to help me to troubleshoot this error?
