How to set environment variables to run ROS project using Qtcreator?
<p>Using Qtcreator to run the ROS projects I get the following error:</p>

<blockquote>
  <p>FATAL] [1473647395.591961066]: 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.</p>
