[Users] mysqlso error

I compile mysql.so with the following command. make modules=modules/mysql modules I have followed the document to configure openuser to use SQL. When I start openser, the error message below is shown. What does it mean the module compile flags? Any clue? openser: ERROR: module compile flags mismatch for /usr/local/lib/openser/modules/mysql.so core: STATS: Off, EXTRA_DEBUG, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT module: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT <mailto:users@openser.org>
