Hi, I'm trying to use a lua script to grab voicemail PINs from Kamailio's db as shown here <http://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc> However, I get the following error message which is driving me nuts. Googling for the "undefined symbol: lua_settop" error message doesn't seem to return anything relevant, and looking around the FS wiki here <https://wiki.freeswitch.org/wiki/Mod_lua> didn't help either. [ERR] mod_lua.cpp:199 error loading module 'luasql.mysql' from file '/usr/lib/x86_64-linux-gnu/lua/5.1/luasql/mysql.so': /usr/lib/x86_64-linux-gnu/lua/5.1/luasql/mysql.so: undefined symbol: lua_settop stack traceback: [C]: in ? [C]: in function 'require' /usr/local/freeswitch/scripts/sqluser.lua:14: in main chunk 2014-07-12 22:21:17.470474 [ERR] mod_lua.cpp:265 LUA script parse/execute error! Any ideas? Thanks
