How to modify and build a rosbuild package from source in ros groovy?
I am trying to modify and build the rosfalcon package. I am using ubuntu 12.04 and groovy.
How do I set up a workspace from an existing package in groovy? There seems to be tons of examples about creating a workspace from scratch, but I couldn't locate any about setting up your environment to modify an already existing package. Everything I tried ended up with either ROS not being able to find that package, or the package not building.
So, if I have the sources for a package I want to modify, where do I place them and which commands should I use to tell ROS it exists/build it/install it?
