Unable to run lua Script in LibreCAD 3

hi, I am tried to run example on LibreCAD manual
http://wiki.librecad.org/index.php/LibreCAD_3_-_Lua_Scripting 
But I am getting folowing error [string "d=app.currentDocument();..."]:1: attempt to index a nil value (global 'app'"

Any help regarding this?

I know that as It used to appear even before LibreCAD doesn't open GUI
interface . I just posted that to show that even no error is shown on
terminal.

And I think we can't say it doesn't start as after ./librecad command
it doesn't exit but Just GUI is not shown.
