Error when running voxl-cross image on Voxl2

[martongonczy]

Hi,
I am trying to run the voxl-cross image on the Voxl2 but after I push the image to the drone and try to run it I get this message.

I only added a few lines to the Dockerfile (to have opencv and numpy) and changed the build command to be compatible with the target environment (linux/arm64/v8) as I had that error originally.

Does someone know what the problem could be? I cannot find any information about this on the internet.

@martongonczy voxl-cross is a docker image you run on your host machine. It has a cross compiler to build applications to run on voxl. On voxl2 you have native compilers installed and don't need a docker.

@Eric-Katzfey Thank you for your reply.

So if I want to have OpenCV and Numpy installed on the drone I have to download it directly onto the drone without using Docker?

@martongonczy OpenCV is already installed on VOXL 2. numpy would require you to install it

@Moderator thank you for your help. When I run cmake it throws an error saying that it cannot locate OpenCV, I am using

Find the OpenCV package

find_package(OpenCV REQUIRED)
include_directories( ${OpenCV_INCLUDE_DIRS} )

This is from the OpenCV documentation but it does not work for me. What could be the solution?
