cound't find AF_INET address #4

after i run the rttlua-gnulinux -i deployment/youbot.lua i am getting below error. I have

Real-time memory: 517888 bytes free of 524288 allocated.

require("rttlib")
rttlib.color = true
tc = rtt.getTC()
depl = tc:getPeer("Deployer")
depl:import("rtt_tf")
depl:loadComponent("tf", "rtt_tf::RTT_TF")
tf = depl:getPeer("tf")
tf:configure()

Either add

depl:import("rtt_rosnode")

to start the ROS node (calls ros::init() internally) or use the "ROS-aware" import function provided by package rtt_ros:

depl:import("rtt_ros")
rtt.provides("ros"):import("rtt_tf")

The import operation of rtt_ros follows the <plugin_depend> dependencies declared in the respective package.xml files, which for rtt_tf would include rtt_rosnode through rtt_roscomm.

Note that the current version of rtt_tf is broken since ROS hydro: orocos/rtt_ros_integration#68

Ok, thanks for helping, now its working, so many things to learn o god :>.
