I have a situation where I need to use two modules... both of which load / reference another module. So I'm getting an error about a loop.

Here's the code in module1: 

require("posix")
posix.setenv("PATH", "/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin")

and in module 2 I have the same thing: 

require("posix")
local ts = posix.stat(spath, "ctime")

I found this post: Lua: How to avoid Circular Requires

I tried to apply what the above post said and I changed my logic in both modules to look like this: 

posix = posix or require("posix")

But I'm still getting the error message. Any suggestions would be appreciated.

EDIT 1

tester.lua

local main =require("main")

main.lua

module (..., package.seeall)
-- Load libraries
require("commonfunctions")
require("luasql.postgres")
require("session")

commonfunctions.lua

posix = posix or require "posix"

session.lua

posix = posix or require "posix"

Error Message

  • Which error message are you getting? What are the modules named? – lhf Dec 18 '13 at 15:11
  • lhf, please check out Edit 1 of my post. Thank you! – dot Dec 18 '13 at 15:20
  • It's not a loop problem like in that SO post you refer to. You don't have A require B and B require A. Does the problem go away if 'main' doesn't require 'session'? Have you tried running each module individually? – Oliver Dec 18 '13 at 16:05
