Description

Hello there,

I am trying to compile the zed-ros2-wrapper inside a docker container that already has ROS2, the Zed SDK, and the additional dependencies.

I am following the instructions to install the wrapper, but I am having an issue by compiling zed_components. Each time I try to compile it (colcon build --symlink-install --cmake-args=-DCMAKE_BUILD_TYPE=Release), I get the expected result (BELOW).

The dependency issue regards to zed_interfaces.

Has someone experienced a similar issue? Any suggestion? Thanks!

Steps to Reproduce

colcon build --symlink-install --cmake-args=-DCMAKE_BUILD_TYPE=Release

Expected Result

Package built successfully

Actual Result

--- stderr: zed_components                         
* Found ROS2 foxy
* ROS2 foxy is officially supported by this package.

ZED Camera model

ZED2i

Environment

ZED SDK Version 3.8.2
zed-ros2-wrapper foxy-humble-v3.8 (I also tried foxy-humble-v3.8.2. without success).
ROS Foxy

Anything else?

zed_interfaces compiles successfully. I have correctly sourced the ROS WS and checked that ROS detects the package. Besides, this is the output of rosdep install --from-paths src --ignore-src -r -y

#All required rosdeps installed successfully

@jprodriguezg you cannot use the master branch with ZED SDK v3.8.2. You must use this release tag: https://github.com/stereolabs/zed-ros2-wrapper/releases/tag/foxy-humble-v3.8.2

[jprodriguezg]

@Myzhar I am using the branch foxy-humble-v3.8 and I also tried foxy-humble-v3.8.2

[Myzhar]

The tag does not include the submodules. You can check it, the folder zed-ros2-interfaces is surely empty. You must fill it with this: https://github.com/stereolabs/zed-ros2-interfaces/releases/tag/humble-v4.0.8 it should be compatible

[jprodriguezg]

Thanks @Myzhar I just moved to branch foxy-humble-v3.8.2 of zed-ros2-wrapper, and to branch humble-v4.0.8 of submodule zed-ros2-interfaces. However, I still have the same issue.

[Myzhar]

What do you get if you try to build the zed_interfaces package separately? $ colcon build --symlink-install --packages-select zed_interfaces

[jprodriguezg]

Here is the output:

Starting >>> zed_interfaces
Finished <<< zed_interfaces [2.37s]                     

Summary: 1 package finished [2.48s]

[Myzhar]

The package is then correctly built. Can you now build all the other packages?

If that's not the case then check your environment settings.

[jprodriguezg]

I get the same error (above) while trying to compile zed_components.

I have sourced my ROS2 workspace and checked $CMAKE_PREFIX_PATH. Everything looks OK.
Are there any other environmental settings that I should take into account?

[Myzhar]

Can you check the content of the folders and subfolders in /home/user/D4A/ras/ros2/sensors_ws/install/zed_interfaces? Are the searched files there?

[jprodriguezg]

@Myzhar thanks for the feedback. All of the files that were reported as having errors are located within the folder. I discovered that some of them are hyperlinks to a file in the build directory which also exists in its respective folder.

@Myzhar Hola, ahora estoy usando este paquete de funciones en ROS2-humble en ubuntu22.04 pero aparece un error: Failed <<< zed_components [11.5s, exited with code 2]

Summary: 2 packages finished [19.2s] 1 package failed: zed_components 1 package had stderr output: zed_components 2 packages not processed

Intenté muchas formas de resolver este problema, pero no funcionó. Espero puedan darme una respuesta.Gracias.
