2019-05-20 01:50:37 -0500	marked best answer	ROS_MASTER_URI set, but program gives related error. Hello, I have ubuntu 14.04 , Ros indigo and Gazebo 2.2.6. I am running a gazebo_ros_control simulation, a simple robot with two movable joints. I can move the robot with rostopic commands. The problem is, that I am trying to publish messages to the topics from another program running in the same PC, but I get the following error: `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.` I have set ROS_MASTER_URI and ROS_IP to my .bashrc file and sourced it. I have tried setting ROS_MASTER_URI and ROS_HOSTNAME. I have tried setting all three of them. I have tried using "192.168.1.2 " instead of "localhost". I have tried to echo the variables and I get the expected result. Ι even tried to format my pc and reinstall everything, in case of broken packages. I always get the same error. What could be the problem? edit: The output of env \| grep -i ros \| sort ROS_ROOT=/opt/ros ROS_PACKAGE_PATH=/home/sofia/catkin_ws/src:/home/sofia/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks ROS_MASTER_URI=http://192.168.1.2:11311 LD_LIBRARY_PATH=/home/sofia/catkin_ws/devel/lib:/opt/ros/indigo/lib CPATH=/home/sofia/catkin_ws/devel/include:/opt/ros/indigo/include PATH=/opt/ros/bin:/opt/ros/indigo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin ROSLISP_PACKAGE_DIRECTORIES=/home/sofia/catkin_ws/devel/share/common-lisp ROS_DISTRO=indigo PYTHONPATH=/home/sofia/catkin_ws/devel/lib/python2.7/dist-packages:/opt/ros/indigo/lib/python2.7/dist-packages ROS_IP=192.168.1.2 PKG_CONFIG_PATH=/home/sofia/catkin_ws/devel/lib/pkgconfig:/opt/ros/indigo/lib/pkgconfig CMAKE_PREFIX_PATH=/home/sofia/catkin_ws/devel:/opt/ros/indigo ROS_ETC_DIR=/opt/ros/indigo/etc/ros the lines I added to .bashrc `source /opt/ros/indigo/setup.bash source ~/catkin_ws/devel/setup.bash export GAZEBO_MODEL_PATH=/home/sofia/catkin_ws/src/ export GAZEBO_PLUGIN_PATH=$PWD:$GAZEBO_PLUGIN_PATH export ROS_PACKAGE_PATH=/home/sofia/catkin_ws/src:$ROS_PACKAGE_PATH export ROS_ROOT=/opt/ros export PATH=$ROS_ROOT/bin:$PATH export ROS_MASTER_URI=http://192.168.1.2:11311 export ROS_IP=192.168.1.2 export ROS_HOSTNAME=192.168.1.2` Edit2: The only reason I started changing ROS variables was the error I am getting by the program. `env \| grep -i ros` output without exporting any ROS enviroment variables: `CMAKE_PREFIX_PATH=/home/sofia/catkin_ws/devel:/opt/ros/indigo CPATH=/home/sofia/catkin_ws/devel/include:/opt/ros/indigo/include LD_LIBRARY_PATH=/home/sofia/catkin_ws/devel/lib:/opt/ros/indigo/lib PATH=/opt/ros/indigo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin PKG_CONFIG_PATH ...` (more)

2017-10-27 03:21:22 -0500	commented answer	ROS_MASTER_URI set, but program gives related error. The ros::init is in the "other executable". I will do that in a day or two, because I have to export some data, now that
