I am in a situation such that to use both diamondback and electric. Is it possible to use both the versions of ros in a same operating system?
If possible, how?
Thanks in advance for your suggestions.
I answered this previously here. Hopefully that will also make it clear how to treat the contents of your .bashrc file. Note that if you have your own source code then you will need to rebuild it after switching which version of ROS you are using.
As @joq says you will find it very difficult (at best) to use two versions of ROS at the same time. You may find more success in using the newer version of ROS as a system install, then any packages (or stacks) that you want to use from older versions of ROS you can install and build from source in one of your user directories. That approach has its own downsides (find fixes to make package work with newer version of ROS) but will be much easier than using two versions of ROS.
Yes, this is possible. If you have both ROS versions installed, you can use e.g. use Diamondback in one Terminal by sourcing the setup.bash of Diamondback:
source /opt/ros/diamondback/setup.bash
and use Electric by sourcing the setup.bash of Electric in another terminal:
source /opt/ros/electric/setup.bash
I have some questions regarding that
In 'bashrc', Should I write source for diamondback or electric or both
If both what will be the result for 'echo $ROS_PACKAGE_PATH'
What will be the result about trying to find a common package for both version. EX. rospack find openni_kinect.
