I'm trying fbclient 0.5.0 on ubuntu 10.10 (maverick 32bit). but getting the following messages.

>lua: /usr/local/share/lua/5.1//fbclient/util.lua:147: attempt to index local 'alien' (a boolean value)

The LuaSocket similarly installed by luarocks is normal. Please see the my test code.

Location is: /usr/local/share/lua/5.1/ alien.lua fbclient/ socket/ ...

What is the cause?

-- test.lua print ("path="..package.path) print ("cpath="..package.cpath)

require 'luarocks.require'

local socket = require( "socket" ) print("socket:".. socket._VERSION)

local fb = require 'fbclient.class' print("fbclient:".. fb._VERSIONN)

-- Result

what does require('alien') return for you?

$ lua Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio

--alien test require 'alien' local buf = alien.buffer(100) print (buf) nil

looks like alien is installed. (Sorry, i'm a beginner of lua)

Then i think that result is run-timing of init.lua, but i got messages as follows.

export LUA_PATH="/usr/local/share/lua/5.1/fbclient/?.lua;/usr/local/share/lua/5.1/fbclient/init.lua" lua test.lua lua: /usr/local/share/lua/5.1/fbclient/init.lua:18: loop or previous error loading module 'fbclient.package' stack traceback: [C]: in function 'require' /usr/local/share/lua/5.1/fbclient/init.lua:18: in main chunk [C]: in function 'require' /usr/local/share/lua/5.1/fbclient/init.lua:18: in main chunk [C]: in function 'require' test.lua:5: in main chunk [C]: ?

I had the same problem but resolution is simple. Edit your alien.lua file (in my kubuntu it is located in /usr/local/share/lua/5.1/) as follows: at the end of file add this line:

return _M;

I hope it helps

It works. Thanks for your help.
