Re: Getting started with lua in eclipse (LDT)

[Benjamin Cabé <bcabe@...>]

Hello Barry,

By default, LDT ships with a built-in Lua VM (based on jnLua) so as anyone without even having to install Lua on its machine can start running Lua scripts real quick. I think that the way you've set the PATH and CPATH, the jnLua VM itself is not found anymore. 

What you probably want is to configure a "local interpreter" for your local native VM. You can use [1] as a reference. Once you have the interpreter set up, you can launch the script against this interpreter instead of the embedded jnLua one by tweaking your launch configuration.

Hope this helps,

Benjamin--

Objet : Getting started with lua in eclipse (LDT)

Hello, apologies for the newbie question:

I am trying to get started with programming in lua using the Eclipse LDT Plugin.

So far I have:

installed the plugin:

Lua Development Tools 1.0.0.201306101641org.eclipse.koneki.ldt.feature.groupEclipse Koneki

installed lua-socket from the fedora repo:

[root@localhost lib]# yum list installed | grep "^lua"

lua.i686                             5.1.4-11.fc18                     @fedora  

lua.x86_64                           5.1.4-11.fc18                     @fedora  

lua-copas.noarch                     1.1.6-4.fc18                      @fedora  

lua-coxpcall.noarch                  1.13.0-4.fc18                     @fedora  

lua-socket.x86_64                    2.0.2-8.fc18                      @fedora

On the run configuration I have set the environment variables:

LUA_CPATH=/usr/lib64/lua/5.1/?.so;?.so

LUA_PATH=/usr/share/lua/5.1/?.lua;?.lua

Now when I try to run a simple "socket" main.lua:

socket = require'socket'

print(socket._VERSION)

I get:

Exception in thread "main" com.naef.jnlua.LuaRuntimeException: error loading module 'socket.core' from file '/usr/lib64/lua/5.1/socket/core.so':

/usr/lib64/lua/5.1/socket/core.so: undefined symbol: lua_gettop

at org.eclipse.koneki.ldt.support.lua51.internal.interpreter.JNLua51Launcher.main(JNLua51Launcher.java:137)

Any ideas what is going wrong ?

Thanks.

Baz.
