ROS master URI is not set

Question

I followed the procedure exactly in the Ubuntu ROS installation page. After installation in ubuntu 12.04 with rosbuild the command 'roscore' returns the error - "ROS master URI is not set".

The following lines are included in ~/.bashrc

ROSLISP_PACKAGE_DIRECTORIES="" ROS_DISTRO="groovy" ROS_ETC_DIR="/opt/ros/groovy/etc/ros" ROS_MASTER_URI="http://localhost:11311" ROS_PACKAGE_PATH="/opt/ros/groovy/share:/opt/ros/groovy/stacks" ROS_ROOT="/opt/ros/groovy/share/ros" source /opt/ros/groovy/setup.bash

Please help me out

Answer 1

What instructions did you follow? This should not be in your .bashrc. It should only have added:

source /opt/ros/groovy/setup.bash
