How do I temporarily swap out a core package with a locally compiled one?
Suppose I found and want to fix a bug in ros_comm. I've forked and cloned a local copy of ros_comm and implemented my fix. How do I go about testing my fix? More specifically, how can I temporarily swap out the current ros_comm installed in my system with my work in progress ros_comm without recompiling the whole ROS stack?
Naively putting ros_comm in the same workspace as my package for testing my fix (test_node) and building (and sourcing) them together doesn't work as it still uses the system installed ros_comm.
that is actually supposed to work, so perhaps you should add some more info on what you did exactly.
hmm that's strange, my test node in the same workspace is still linking to the system
ros_commpackage, not the customros_commpackage in the local workspace... It seems to be related to this question
