Can't compose Dockerfile during 'colcon build'

[zhuhaier1992]

The error msg are as follows:

It seems that /usr/bin/python3.10 can't find a module called rosidl_adapter. So I have tried add a command in Dockerfile that install rosidl_adapter by RUN apt-get install ros-humble-rosidl-adapter. Then it says it's already installed, and shows this same error msg again.

I updated the humble and iron docker files. Try to pull and then build the image.

Hi Jeguzzi, thank you for your prompt reply! Yet I met another problem when I run sudo docker compose up, it reports:

[+] Running 2/0
 Container ep-teleop-1  Created                                      0.0s

 Container ep-driver-1  Created                                      0.0s

Attaching to ep-driver-1, ep-teleop-1

ep-driver-1  | exec /ros_entrypoint.sh: exec format error
ep-teleop-1 exited with code 1
ep-driver-1 exited with code 1

If I run sudo docker build --platform linux/amd/v3 ., it reports:

And if I run: sudo docker run -it f38430005841 # id of jeguzzi/robomaster_ros, then it reports:

The requested image's platform (linux/arm64/v8) does not match the detected host platform (linux/amd64/v3) and no specific platform was requested
exec /ros entrypoint.sh: exec format error

I don't know if it's because I am running ubuntu20 on vmware. I will try to do it on physical machine tomorrow.

Hi @zhuhaier1992 ,

in case you still have the problem, I image that it is caused by pulling the docker image from my docker hub repo, and getting the wrong architecture. Try to build the image locally. I don't know why the build failed but most probably it does not have a direct link to the robomaster_ros image.
