no roshandle and ros::init present in rtt_ros pkgs?

[Dinesh Lama]

When ever i ty to rttlua-gnulinux -i deployment/youbot.lua below error comes:

[FATAL] [1521766153.873659483]: You must call ros::init() before creating the first NodeHandle
Couldn't find an AF_INET address for []
Couldn't find an AF_INET address for []
[ERROR] [1521766153.896688903]: [registerPublisher] Failed to contact master at [:0]. Retrying...
Couldn't find an AF_INET address for []
Couldn't find an AF_INET address for []

even after i modified the cpp files same error si comming.
the youbot.lua file is:

-- In order to run this script, use:
-- rttlua-gnulinux -i deployment/youbot.lua

-- See also http://www.orocos.org/wiki/orocos/toolchain/LuaCookbook

require("rttlib")
rttlib.color = true -- Since we're running this script with -i

depl:connect("youbot.cmdvel","controller.cmdvel", cp);
depl:connect("youbot.cmdvel","teleop.cmdvel", cp);

-- Deployment Exercise:
-- Configure or start the necessary components:
-- areadetection, nobot (if applicable), supervisor
-- Remember that the supervisor has the authority to
-- control (start/stop) most components.
sup:start()

-- Deployment Exercise:
-- Visualise the current setup with the rtt_dot_service
-- Use rosrun xdot xdot.y orograph.dot to visualize
-- call generate again to update the graph

-- user/test commands:

cmd = rttlib.port_clone_conn(sup:getPort("events"))
cmd:write("e_circle")
cmd:write("e_manual")
So what is the problem?
