External Lib : Lua LOOP not running [message #988928]

Hello,

I am new to LDT ( using version 0.9) under Debian Linux and I like it so far.
I can run Lua files within the LDT and it shows the output in the console.

However, if I use external libraries, errors will appear when trying to run them.

For example I tried to use the LOOP library :

local oo = require "loop.base"

I installed LOOP via LuaRocks and I can run classes based on LOOP without any problems on the Linux Shell.

However, running it in Linux will cause the following error message :

at org.eclipse.koneki.ldt.support.lua51.internal.interpreter.JNLuaLauncher.main(JNLuaLauncher.java:137)

How can I fix it so that I can use LDT for LOOP-based lua files, too.

Hi,

It sounds like there is a difference between the $LUA_PATH available from your terminal and the one available from where you run Koneki LDT.
Do you modify your $LUA_PATH in your .bashrc?
You can check this easily by running the following from shell and from a Koneki LDT project.

print( package.path )

If outputs differ, Koneki LDT and shell do not use same $LUA_PATH.
I think you might either uniform your $LUA_PATH or use the Lua interpreter of your system.

Kevin
