missing dependency with ddynamic_reconfigure #812
Comments
|
Hi,
Therefor, the fix for the error is |
|
@doronhi Then I get the following error: I am testing with a D435 and T265, both now working in the Realsense Viewer after I upgraded the firmware on the D435 to 05.11.01.100. The T265 didn't require any firmware update (Just FYI). |
|
@doronhi I am running: When running the following commands, I get... version: 1.1.2.realsense-1.3.5 command: sudo apt-get update |
|
A new GPG keys were deployed for packages.ros.org. |
|
And if I'm using ros melodic on Ubunto 18.04.2? |
|
See #790 |
|
@doronhi |
|
I am getting that error too and I did your steps. |
|
The message you posted states "Report the problem to the maintainer 'Noam Dori theNODO55@gmail.com". |
|
Hi @dorodnic , |
|
Yes,I cloned it by myself and not by apt-get and it is work. |
|
I am also running ROS melodic on ubuntu 18.04.2, tried to build the ROS node source 2.2.6, ran into the same issue (ddynamic_reconfigure was missing from catkin_ws/src), cloned it from https://github.com/pal-robotics/ddynamic_reconfigure, and everything build smoothly then. Thanks for the help here. |
What do you mean by "default source"? The realsense2_camera does not state a source for ddynamic_reconfigure. |
|
You can also try deleting the |
|
I have the same issue and do not know how to solve ... @doronhi @PhilippeRerole Thanks guys! |
|
Sorry for misleading anyone. I didn't mean that "ddynamic_reconfigure" is not needed. Simply that it is not built by realsense2_camera and that the source code for that package is not included or pointed to by realsense2_camera. The package "ddynamyic_reconfigure" is needed for building and running realsense2_camera. |

Still need any further clarification for this topic? If not, will close this. |

No further clarification needed. Unit is operational.

I'm getting the same error on ubuntu 18.04, so the package is not available yet, right? |
|
The package is available for ubuntu 18.04. type: |
|
is it avaialable for windows? |

The lack of this package up-to-date source breaks all ros1 installs done from source. Hence, the issue at hand should be open. While one can compile using the source here. The package has not been updated or known to work since ros kinetic. This renders Realsense's useless in real world robotic scenarios. For example, using the Jetson Nano for inference with Realsense. That is, the Nano official image has Ubuntu 18.04 and running native ros1 with python3 requires installation from source. Other hacks are possible (like docker, upgrading manually) none of which will work with realsense (at least not with 435i or 455). |

Hi @dnovischi ddynamic_reconfigure can be manually installed using sudo apt install with specific versions for Kinetic, Melodic and Noetic. This instruction is used instead of cloning the source. Kinetic Melodic Noetic |

Hi @MartyG-RealSense, I don't understand how having some packages solves the issue. The setup is the following:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ros-noetic-ddynamic-reconfigure : Depends: libgcc-s1 (>= 3.0) but it is not installable
Depends: libstdc++6 (>= 9) but 8.4.0-1ubuntu1~18.04 is to be installed

Depends: ros-noetic-roscpp but it is not going to be installed
E: Unable to correct problems, you have held broken packages.So, @MartyG-RealSense what am I missing? What is the solution for installations from source? |

In the RealSense ROS1 wrapper, ddynamic_reconfigure is a required component. It allows changes to settings to be made dynamically during runtime after launch instead of in a launch file or roslaunch instruction before launch. It is not required in the ROS2 wrapper. ddynamic_reconfigure can be installed by cloning its source as the wrapper installation instructions suggest. Whilst it is certainly valid to install it this way, I personally always recommend installing it from packages instead by using the apt-install packages for particular ROS1 branches that I listed above. The reason for this recommendation is simply because it is an easy installation method. Checking carefully through your detailed description of your complete installation procedure on Jetson, I cannot see anything that is obviously incorrect and you have installed the various components in the appropriate order (librealsense, ROS, ddynamic_reconfigure, RealSense ROS1 wrapper). Your librealsense / Python installation is also working correctly. There are occasionally problems with the ROS1 wrapper that are not correctable no matter what is tried, but are suddenly resolved if the entire catkin_ws/src catkin workspace folder is deleted and the wrapper is built from source again by following the instructions from the beginning after the catkin_ws/src folder is recreated. Choose to either install ddynamic_reconfigure from source or packages but do not use both methods. |
So the best bet when using Jetson Nano is to do a distribution upgrade to ubuntu 20.04 and switch to ROS2?
I'll give it a try. Also can you post your way of re-configuring udev rules? On the other hand, what's your recommended way of using Realsense (435i and/or 455) with Jetson Nano based on a python3.x version? (I really don't care about the OS, as long as I can run ROS on python3. Our code requires tensorrt compiled models to run inside of ros nodes). Thanks and Happy New Year! PS: I'll post findings for this in more appropriate issue, as continuing the discussion here is kind of out of scope. (Probably in #2580) |

You are very welcome! A RealSense user provides a complete guide at #2197 (comment) for using Python 3 with Jetson Nano and RealSense D455. The guide at the link below may also be worth reading, although it is not specific to RealSense or Jetson. https://idorobotics.com/2020/08/19/setting-up-ros-with-python-3-and-opencv/ |
on the last updates, the dependency folder ddynamic_reconfigure has changed the name to realsense2_description. However, the CMakeLists.txt on those updates (tags 2.2.5 and later) still link to ddynamic_reconfigure (lines 18 and 76), which creates the following error:
CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by
"ddynamic_reconfigure" with any of the following names:
Maybe it passes the test based on some cached build, but this is clearly a broken dependency link.
