Hello Guys,

First of all my OS is Ubuntu 16.04 with Ros Kinetic and Gazebo 7.0. I installed that with full desktop install.

i followed the tutorial on :

everything works fine until i got to the ros part. I worked with ros before with turtlebot package and there everything works fine too...

when i type in :

cd ~/velodyne_plugin/build
source /opt/ros/kinetic/setup.bash
gazebo ../

i got :

[FATAL] [1509043732.797014978]: ROS_MASTER_URI is not defined in the environment. Either type the following or (preferrably) add this to your ~/.bashrc file in order set up your local machine as a ROS master:

export ROS_MASTER_URI=http://localhost:11311

then, type 'roscore' in another shell to actually launch the master program.

when i echo ros_master_uri i got the local host address... i have no idea what i am doing wrong

This reminds me of #q274044. Can you check that question and see whether you're seeing the same things?

Can you please add what OS this is, which version, how you installed your OS, which version of ROS and how you installed that.
