[Freeswitch-users] Latest FreeSWITCH pull and Lua

[James Mortensen]

Okay, so I figured out that the multiple Lua VMs detected is because the
version of Lua was slightly different than the compiled .so file for
LuaXML_lib, even though it said it was the right version. So I recompiled
it and added it into the /usr/local/lib/lua/5.2 folder, and I put
LuaXml.lua into /usr/local/share/lua/5.2.

Now, I'm seeing these undefined symbol errors and will need to tackle this
next:

2013-12-12 07:41:53.395054 [ERR] mod_lua.cpp:199 error loading module
'LuaXML_lib' from file '/usr/local/lib/lua/5.2/LuaXML_lib.so':
 /usr/local/lib/lua/5.2/LuaXML_lib.so: undefined symbol: lua_gettop
stack traceback:

/usr/local/share/lua/5.2/LuaXml.lua:1: in main chunk
[C]: in function 'require'
