[Freeswitch-users] LUA ESL Help

[Chad Phillips]

You shouldn’t need any ESL.lua — pretty sure that’s just part of the search when “require ‘ESL’” is called, and /usr/lib64/lua/5.1/ESL.so should satisfy that search. Not sure why the symlink isn’t working, as an experiment, did you just put the ESL.so there directly? I’d also try adding to CPATH.
