def topological_sort(dependency_graph):
    """ Topological sorting algorithm.

    Args:
        dependency_graph: A mapping type whose keys represent graph nodes.
            Dependencies are indicated by the values which are sets containing
            keys for other nodes.
            Note: a node with no dependencies is a key indexing an empty set.

Building ROS on OS X

This is a fork of @mikepurvis original ROS indigo installation notes. I tried to find a straightforward way to keep the system Python throughout the build. I ran into some well known issues while building rviz and had to extend the header exclusions for moc a bit more.

Helpful Stuff

catkin build options

• -p # (parallel jobs)
• catkin build pkg_name to build a certain package with dependencies
• --start-with pkg_name skip dependencies up to a certain package
• the two above combined allow for a quick retry if one package keeps failing
