RE: query in mib2c

Hi Janki

Did MIB2C also create any files for you that ended with the words: …_data_get.c or …_data_access.c  ?

I ask because when I ran MIB2C it generated these files to give me an opportunity to write functions that would be called when the SNMP agent wanted to fetch a value to return to the manager when it is polled. I wrote in those functions, compiled and ran the executable and it attached to the snmp agent as an agentx subagent.

But then I  used a different config file (mib for dummies) so I will have different results, but in any case someone needs to write some code to return values for the MIB variables. You may have done so but I did not see it in your email.

This page: http://www.net-snmp.org/wiki/index.php/TUT:mib2c_scalar
Says…

The mib2c scalar configuration file<http://net-snmp.git.sourceforge.net/git/gitweb.cgi?p=net-snmp/net-snmp;a=blob_plain;f=local/mib2c.scalar.conf;hb=HEAD> generates a bare-bones skeleton handler for each scalar object. You must then write code to provide data for the object, handling each mode.

Did you do that ?

Subject: Fwd: query in mib2c

Hi

I am working on net-snmp since past few days. I want lldpLocChassisId from Q-BRIDGE-MIB.
I have added the mib and able to translate the OIDs.
Now I want to do get.
I did mib2c -c mib2c.scalar.conf lldpdLocalSystemData. lldpLocSystemData.c and lldpLocSystemData.h files are generated in the folder /agent/mibgroup
I ran ./configure --with-mib-modules"lldpLocSystemData", make and sudo make install

lldpLocSystemData.o and lldpLocSystemData.lo files are generated.
When I do snmpget -v 2c -c public localhost Q-BRIDGE-MIB:: lldpLocChassisId, I get unidentified object error.
When I run gcc lldpLocSsytemData.c -c lldpLocSystemData.o, it gives undefined reference to functions snmp_get_do_debugging, debugmsgtoken, debugmsg, netsnmp_create_handle_registration, netsnmp_register_scalar, snmp_set_var_typed_value, snmp_log.

Can anyone please help me? I am attaching .c and .h files
