Several and independent workspaces

Hi everyone,

For my training with ROS, I would like to create an additional workspace (e.g. in ~/catkin_ws2/) next to an existing one (~/catkin_ws/). Assuming that ROS Indigo was already installed on my computer, I followed the ROS tutorials to setup another catkin workspace :

$ mkdir -p ~/catkin_ws2/src/
$ cd ~/catkin_ws2/src/
$ catkin_init_workspace

Then I run catkin_make in ~/catkin_ws2/ and added the lines

source /opt/ros/indigo/setup.bash
source /home/myhome/catkin_ws2/devel/setup.bash

at the end of my .bashrc file in /home/myhome/. I specify that I already did all of this with the previous workspace.
But when I echoed the $ROS_PACKAGE_PATH, there were still the path of ~/catkin_ws/ in it. Why is it still here since I didn't tell to ROS that the first workspace still exists ?

Many thanks for your replies.

That means that the workspace in ~/catkin_ws/ was sourced when you built the workspace in ~/catkin_ws2/. You'll have to clear the build, devel, and install folders of ~/catkin_ws2/ and in a new terminal (without sourcing stuff in your ~/.bashrc) source /opt/ros/indigo/setup.bash and then build ~/catkin_ws2/ with catkin_make.
