Hi,

I'm trying to set my ROS_PACKAGE_PATH variable permanently. I appended the following line to the etc/environment file: ROS_PACKAGE_PATH="/home/zayin/catkin_ws/src:/opt/ros/groovy/share:/opt/ros/groovy/stacks". Then, I logged out and back in. However, when I type echo $ROS_PACKAGE_PATH in the terminal, I get /opt/ros/groovy/share:/opt/ros/groovy/stacks, which is the initial setting. What have I forgotten to do? Thanks!

Similar questions/answers exist - see here, here.

Unless you add your workspace to the package path in your ~/.bashrc file, each time you open a new terminal you will need to source your workspace (see this tutorial).

To set your workspace permanently, open your .bashrc file in a text editor, for example -- gedit ~/.bashrc -- and add

export ROS_PACKAGE_PATH=/your/path/to/workspace:$ROS_PACKAGE_PATH

at the bottom of your file. Obviously, make sure you change "/your/path/to/workspace" to your exact workspace path..

I don't understand the last part :$ROS_PACKAGE_PATH Should it be like this ROS_PACKAGE_PATH=/home/hjt/catkin_ws/src:$ROS_PACKAGE_PATH

The ":$ROS_PACKAGE_PATH" means that you are adding "/home/hjt/catkin_ws/src" to the start of the ROS_PACKAGE_PATH, whereas if you just did "export ROS_PACKAGE_PATH=..." then the new ROS_PACKAGE_PATH would overwrite the existing path.

May be you have defined ROS_PACKAGE_PATH in your ~/.bashrc file or you are sourcing other file after defining this variable. Look for something like source /opt/ros/groovy/setup.bash.

I just checked, and no, it's not there. Any other file I should check?

check the answer.

There's nothing like source /opt/ros/groovy/setup.bash in ~/.bashrc.

Zayin ( 2013-05-10 05:56:46 -0600 )edit

can you post the content of .bashrc?

I finally got it to work by adding "source ~/catkin_ws/devel/setup.bash" at the end of the file. Echo works fine and I can use rosrun right after opening my terminal. Thanks for your help!
