Running dynamic-apps helloworld binary on Ubuntu 22.04 container gives errors #9

Closed jobpaardekooper closed 1 year ago

jobpaardekooper commented 1 year ago

Trying to run helloworld from the dynamic-apps repo inside a ubuntu 22.04 docker container is giving me errors. Running with app-elfloader_kvm-x86_64 and app-elfloader_kvm-x86_64_full-debug both give different errors.

I am running the container with the following command:

docker run --security-opt seccomp=unconfined --privileged --rm -it unikraft.org/hackathons/base:latest /bin/bash

Running cat /etc/os-release gives the following output:

PRETTY_NAME="Ubuntu 22.04.2 LTS"

I cloned this repo and inside that folder I cloned the dynamic apps repo.

Running ./run.sh -k app-elfloader_kvm-x86_64 -r ./dynamic-apps/lang/c/ /lib64/ld-linux-x86-64.so.2 /helloworld gives the following output:

The issue was that it should be run should be run with the following command:

./run.sh -k app-elfloader_kvm-x86_64 -r ./dynamic-apps/lang/c/ ./dynamic-apps/lang/c/lib64/ld-linux-x86-64.so.2 /helloworld

It should use the loader that is inside the extracted folder and not the loader of the docker container itself.
