arm-none-eabi.buildenv

Arm bare metal compilation environment.

Creating the image

The following command can be used to create an image from the docker file. It is assume the Dockerfile is located in the same directory.

docker build -t arm-none-eabi.buildenv .

Usage

The working directory of the image is /work. To use the image call it similar to the following examples:

docker run --rm -v $(pwd):/work --user $(id -u):$(id -g) arm-none-eabi.buildenv make

This puts your current work directory into the container, builds your code and afterwards it removes the container.

docker run --rm -v $(pwd):/work --user $(id -u):$(id -g) -it arm-none-eabi.buildenv /bin/bash

This puts your current work directory into the container and starts an interactive bash from the container.

Example output

docker run --rm arm-none-eabi.buildenv arm-none-eabi-gcc --version
