This docker container will reproduce an environment with the SLAC specific buildroot tool used to cross compile kernel modules and packages.
The docker images are published in https://hub.docker.com/r/jesusvasquez333/buildroot/
docker pull jesusvasquez333/buildroot
From the directory where the source code of your package/module is locate run:
docker run -ti -v ${PWD}:/home/build/ jesusvasquez333/buildroot
By default make will be run when the container starts. If you need to run something different, you can start the container with:
docker run -ti -v ${PWD}:/home/build/ jesusvasquez333/buildroot /bin/bash
You will be inside the container with your source code located in /home/build/. You can can then run the specific command you need to build your package/module.
