Hi,

I am using rosinstall-0.5.16. I am troubled by a infinite recursion when calling rosinstall. (in python script /usr/local/bin/rosinstall line 518). I am puzzled by this behaviour that appeared only recently.

My rosinstall config file (stripped down to the offending lines) is

  - other: {local-name: /opt/ros/diamondback/ros}
  - other: {local-name: /opt/ros/diamondback/stacks}

and I believe, I am doing something wrong here. I get the following error when calling

$ rosinstall . my.rosinstall
  [...]

There's an open ticket with this symptom. It's caused by a .rosinstall in the parent directory.

Your rosinstall file looks good. Are you, by chance, executing rosinstall . my.rosinstall in a subdirectory of /opt/ros/diamondback? Try the following:

mkdir $HOME/ros
rosinstall $HOME/ros my.rosinstall

You need to make sure that rosinstall doesn't find a file named .rosinstall from the directory you are calling rosinstall on up to your filesystem root.

Nope, I never modify /opt/ros/diamondback. The hint with the .rosinstall file in the parent did the trick.
