Realsense-ros: missing dependency with ddynamic_reconfigure

[tanismar]

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:

ddynamic_reconfigureConfig.cmake
ddynamic_reconfigure-config.cmake

Maybe it passes the test based on some cached build, but this is clearly a broken dependency link.

Hi,
A couple of changes happened.

1. The folder ddynamic_reconfigure was removed in favor of the newly released debian package ddynamic_reconfigure.
2. The folder realsense2_camera was split to realsense2_camera and realsense2_description, for reducing the package basic size.

Therefor, the fix for the error is
apt-get update apt-get install ros-kinetic-ddynamic-reconfigure

I had the same catkin build error as tanismar, and ran:
sudo apt-get update
sudo apt-get install ros-kinetic-ddynamic-reconfigure

Then I get the following error:
Err:1 http://packages.ros.org/ros/ubuntu xenial/main amd64 ros-kinetic-ddynamic-reconfigure amd64 0.2.0-0xenial-20190325-154841-0800

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]

A new GPG keys were deployed for packages.ros.org.
Follow the instructions here
In short, do the following:
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
sudo apt-key del 421C365BD9FF1F717815A3895523BAEEB01FA116
And now try
sudo apt-get update
again.
After that install ddynamic_reconfigure package.

And if I'm using ros melodic on Ubunto 18.04.2?
This package used to work with melodic, but now the ddynamic_reconfigure is missing and I can't find it for melodic distribution.

See #790

Thank you for the updated key. Still getting an error on update:

I am getting that error too and I did your steps.
CMake Error at /home/arl/catkin_ws/devel/share/ddynamic_reconfigure/cmake/ddynamic_reconfigureConfig.cmake:113 (message): Project 'ddynamic_reconfigure' specifies '/home/arl/catkin_ws/src/realsense/ddynamic_reconfigure/include' as an include dir, which is not found.

[doronhi]

The message you posted states "Report the problem to the maintainer 'Noam Dori [e-mail]".
It seems that you have cloned ddynamic_reconfigure from a wrong source. If you indeed in a need to build that package yourself and not use apt-get install, try cloning the package from here

[tanismar]

Hi @dorodnic ,
I followed your steps by installing ddynamic_reconfigure package, and checking out tag 2.2.6, and run into the same error as ARLVOL. If it is installed from a wrong source, means that the default source is wrong. Can this be fixed? thanks!

[ARLVOL]

Yes,I cloned it by myself and not by apt-get and it is work.
It will be better to update it from the apt and not clone it every time.
tnx

[PhilippeRerole]

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.

[ConnorChristie]

You can also try deleting the build folder in your catkin_ws then re-running catkin_make. This worked for me

[zblcm]

I have the same issue and do not know how to solve ...

@doronhi
Hi, if you see realsense-ros/realsense2_camera/CMakeLists.txt it shows "ddynamic_reconfigure" is required now in line 18. Should I simply remove that requirement, since you said reansense does not rely on it long time ago?

@PhilippeRerole
Hi, did you do any extra operation after cloned and installed ddynamic_reconfigure from gihub?
I have cloned source, compiled then installed, but the same error pops again.

Thanks guys!

[doronhi]

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?

[doronhi]

The package is available for ubuntu 18.04. type:

sudo apt-get install ros-melodic-ddynamic-reconfigure
