i believe there are two missing preprocessor directives in mib.cpp (Agent++v3.5.12 released 4/29/2003). when SNMPv3 support is turned off, Mib::get_boot_counter and Mib::set_boot_counter should not be defined. thus the following two lines should be added: 2688d2687 < #ifdef _SNMPv3 2700c2699 < #endif Todd
