circular dependency

asked 2011-03-10 06:31:37 -0600

Are there any ROS tools to help me track down circular dependencies between my ROS nodes?

As a follow up, I thought i had a circular dependency in my packages because when i call rosmake with a few of my stacks, i see this message: [rospack] woah! expanding the dependency tree made it blow up.

Note that dependencies are between packages or stacks, not nodes.

To list the dependencies of a package named foo:

$ rospack depends foo

To list the packages that depend on foo (directly or indirectly):

$ rospack depends-on foo

But when I manually created a circular dependency in some packages, they would not even compile. Because rosmake found the circular dependency right away. Even if I tried to compile with the "-s" flag.
Maybe that message is only for inter-stack circular dependencies? But rosmake seems to handle it fine, so i am not worried about it.
