I have installed both ROS Hydro and ROS Indigo on Ubuntu 12.04. I want to know how to switch between these versions when I am compiling a catkin workspace in Ubuntu. I have two catkin workspaces, one of them works with ROS Hydro and the other works with ROS Indigo. So, if I want to do a catkin build of the catkin workspace based on ROS Indigo, then what should I do?

Thanks

In a new terminal you need to run

source /opt/ros/indigo/setup.bash

That will set your current terminal to use Indigo. Be careful that you don't source any other Hydro setup.bash files in your ~/.bashrc file or you might start overlaying packages, which is probably not what you want to do.

To switch back to Hydro, you need to open a new terminal and run

source /opt/ros/hydro/setup.bash

Sourcing a different setup file does not affect previously configured workspaces. You need to wipe the build/devel folder and rebuild the workspace with the different environment.
