Hi all,

Is it possible to have several catkin workspaces and to source them sequentially in the .bashrc without conflict or may we experience issues with that?

source /ws1/devel/setup.bash
source /ws2/devel/setup.bash
source /ws3/devel/setup.bash
# ...

Thanks

Effectively the last line will "overwrite" all previously sources workspaces. You should chain your workspaces on top of each other as described in the answer from @joq and only source the leaf workspace.

For people having packages coming from different git/subversion repositories with their own file hierarchy not catkin-compliant and wanted to create several catkin workspaces because of these, I suggest to create a unique "central" catkin workspaces with symbolic links pointing to your git/svn repos, by this way you don't break the file hierarchy of your repos.

Problems are likely to arise. That approach is not recommended.

What should work reliably is to create

ws1 as an overlay of /opt/ros/hydro.setup.bash (for example)
ws2 as an overlay of ws1
ws3 as an overlay of ws2

Then, source /ws3/devel/setup.bash.

Oops. This might explain some problems I've been having. Thanks, ROS Answers!

I'm following the tutorial about how to create a proper overlay (http://wiki.ros.org/catkin/Tutorials/workspace_overlaying) but I don't get it. What do they do different from me with my 3 "source"? I don't have this message "This workspace overlays blablabla" so I'm missing something but what?

I don't think the documentation is very clear about this. What I posted is the recommended solution. Maybe others can explain why.

That is what I wanted to do, but how do you create an overlay, then? I found out that tutorial above and... apparently what it does is only sourcing all setup.bash in the right order. Isn’t it what I was doing in my initial post?
