When several catkin workspaces overlap on the same machine, especially with identically named packages, you may not discover which copy is actually running until something fails.</p> <p>These are my notes from consolidating and migrating workspaces: understand how catkin finds packages, simplify the source chain in order, and finally restore hardware bindings such as udev rules.</p>
