The value returned for a MIB object of syntax ASN_OBJECT_ID
should be of type "oid[]"   (not a string),   and the 'var_len' field
should be the size of this (in bytes, not subidentifiers).

I strongly suspect that you probably need to do something with
'strRetValue.c_str() to ensure it is an array of 'oid' values.

And if this always contains 14 subidentifiers, then you also need

   *var_len = 14 * sizeof(oid);
