Note: If you are building on a memory constrained system you might want to limit the number of parallel jobs by setting e.g. In this scenario, you could externalize the global planner to a standard computer/laptop, which is working remotely from the robot. Note that if you wish to build 'dev' and you wish to build C++ CORBA support then you must have installed a debug version of TAO. The latter will be used to monitor all robots, and create a path for each one so they do not collide with the environment and other robots. Thanks for contributing an answer to Stack Overflow!
