Hello, everyone! I see ROS is a real distributed system, all nodes use node_name and node_uri to identify itself. Now I need to write a monitor process, to monitor all nodes on the same machine.

From http://wiki.ros.org/ROS/Slave_API , I can use getPid( ) to get the PID of that node server. But how can I check if that node is running on the same machine ? Is there a standard way of doing this ? Thanks!

Hello, everyone: I see Master is a xmlRPC server that maintains all the information of all nodes, but when a node abnormal exited, that node still can be seen on the master ? How can I check the active status of that node? Thanks!

So is there possibility that your qt_ros_interface CMakelists is wrong ? I don't know .... maybe should use find_packag

Could you paste the CMakelist file of package robis_math_utilities ? Did it create a cmake config file for the package

Well, the cmake file seems correct. But I see your edited question, "can't parse dependency ros-kinetic-robis_math_uti

Hello, everyone,

I have some packages that are not located in the repo root, so I need to find an example of a release repo in the rosdistro file to finger out how to list these packages correctly ? But I can't find one...

From this link http://wiki.ros.org/bloom/Tutorials/F... , packages should be list like:

foo: packages: foo_msgs: foo_server: foo_utils: But the kinetic rosdistro file shows:

  packages:
  - hector_compressed_map_transport
  - hector_geotiff
  - hector_geotiff_plugins
  - hector_imu_attitude_to_tf
  - hector_imu_tools
  - hector_map_server

There isn't colon at the end of each package.

When packages are not located in the root dir:

packages:
  foo_msgs: util/foo_msgs
  foo_server: tool/foo_server

I tried this use python yaml module, packages as a dict, and foo_msgs as a key. But there don't have paths information in the created rosdistro file ? I don't know what I did wrong, Thanks!

Edit: Hello, I checked the code in rosdistro package:

class Package:

def __init__(self, name, repository_name):
    self.name = name
    self.repository_name = repository_name

    # for backward compatibility only
    self.subfolder = None
    self.status = None
    self.status_description = None

The subfolder is always None...

So this means new rosdistro file doesn't support putting packages in subfolders anymore ? I have to put all packages in the root of repo ?

Edit: Thanks for suggestions from @gvdhoorn, I should add more information about the problem!

Actually, I want to use bloom to release my project, but I don't want it to open pull request for me. I am using a local custom rosdistro, so I need to fill the release info into my rosdistro file including the packages list in my project repo. Then the problem is that rosdistro module can't parse the yaml correctly when the listed packages are not in the top directory of my repo... like can't find package.xml or can't find its depends... So I want to know is there a way to list packages name and their paths in the yaml file, and rosdistro module can parse and find package's depends correctly ? Thanks!

Well, I just wrote a demo to want to prove the problem. But I found out I was wrong. I used the rosdistro module uncor

@gvdhoorn, I have updated my question adding some details, Thanks!

@billyDong , I saw the log of fakeroot, it seems that cmake can't find 'robis_math_utilities' , maybe you need to instal

It works! Thank you very much!

Hi, everyone! Suppose I have two ros projects to develop at the same time, A and B. B use some exported files of A. But I can't source A and B devel/setup.bash at the same time... And I don't want to put A and B in one catkin_ws.

Thanks!
