voxl-emulator won't start
-
I have an Ubuntu 20.04 machine with docker installed.
I have followed these instructions to install
voxl-docker
.I have downloaded the latest voxl-cross, voxl-emulator, and voxl-hexagon from here. I have used
docker load
to create docker images from each of these tar.gz files.When I try to run the emulator, it gives me the error below:

As I understand it, It's telling me that there is no such thing as /bin/bash in the container. I don't really believe that is true, because this webpage uses the
bash
command:voxl-docker -i voxl-emulator -e "/bin/bash build.sh"
.Can you help me understand what I am doing wrong (and why this is not working)?
===============
What I am trying to (eventually) do is to build my own docker image (in Ubuntu) that I can
adb push
to my VOXL and run it there. As I understand it, if Idocker build <path_to_my_own_dockerfile>
on my Ubuntu machine, once I transfer it to the VOXL, it won't work because the architecture is not the same.If I want to
docker build
on my Ubuntu machine and have it work on the VOXL, I believe I will need to run the voxl-emulator anddocker build
inside of that. Is that correct? -
This post is deleted! -
Update: I completely removed docker and voxl-docker from my system.
I rebooted, reinstalled docker, and followed these steps to install voxl-docker.
Now, I get a different error (same as here) :
jared@jared-ubuntu:~/voxl-docker$ voxl-docker -i voxl-emulator -e "/bin/bash" launching image: voxl-emulator with the following command: docker run --rm -it --net=host --privileged -w /home/jared --volume=/dev/bus/usb:/dev/bus/usb -e LOCAL_USER_ID=0 -e LOCAL_USER_NAME=root -e LOCAL_GID=0 -v /home/jared/voxl-docker:/home/root:rw -w /home/root voxl-emulator /bin/bash standard_init_linux.go:228: exec user process caused: exec format error
I followed the instructions at the link. The first two commands ran without any issues. I had to modify the last one to fit my architecture:
sudo apt-get install qemu binfmt-support qemu-user-static docker run --rm --privileged multiarch/qemu-user-static --reset -p yes jared@jared-ubuntu:~/voxl-docker$ docker run --rm -t amd64/ubuntu uname -m Unable to find image 'amd64/ubuntu:latest' locally latest: Pulling from amd64/ubuntu 7b1a6ab2e44d: Pull complete Digest: sha256:7cc0576c7c0ec2384de5cbf245f41567e922aab1b075f3e8ad565f508032df17 Status: Downloaded newer image for amd64/ubuntu:latest x86_64
That worked. Now the voxl-emulator appears to work too:
