Full code of my scalar registration. Changed to register all scalars one by one
instead of in group.
The oid_wrapper class is a wrapper around oid that contains an oid pointer and
the length of that oid.
The scalar class cointains data on each scalars.
void
myclient::registerScalars() {
int scalar_counter = 0;
map<oid_wrapper, scalar>::iterator scalar_iterator;
for (scalar_iterator = scalars.begin();
scalar_iterator != scalars.end();
scalar_iterator++) {
const oid_wrapper _oid_wrapper = (*scalar_iterator).first;
const scalar _scalar = (*scalar_iterator).second;
const string scalar_name = _scalar.getName();
const oid *scalar_oid = _oid_wrapper.getOid();
const long scalar_length = _oid_wrapper.getLength();
const char *buffy = scalar_name.c_str();
int returnValue = netsnmp_register_scalar(
netsnmp_create_handler_registration(buffy,
handle_snmp,
scalar_oid,
OID_LENGTH(scalar_oid),
HANDLER_CAN_RONLY
));
if (returnValue == MIB_REGISTERED_OK) {
scalar_counter++;
} else if (returnValue == MIB_DUPLICATE_REGISTRATION) {
} else if (returnValue == MIB_REGISTRATION_FAILED) {
}
}
cout << "Number of scalars registered: " << scalar_counter << endl;
}
The output is always only 1.

Do the other groups use the same "root" OID as the first registration,
or do they all use different roots?
The usual cause of a duplicate registration would be having two
invocations of netsnmp_register_xxx() with the same root OID
(i.e. the third/fourth parameters to the
netsnmp_create_handler_registration call)
If that's not the case, it's probably worth posting the full code
of the block used to register these groups.
