This is a Dockerfile that contains tools to compile, run and debug ARM programs. More specifically, it contains the GCC toolchain for ARM, gdb-multiarch and qemu. This image is intended to be used as a semi-permanent environment for running and compiling ARM binaries, rather than for running one-off commands.
Use the following command to build the image:
sudo docker build . -t xshill/arm --build-arg UID=<MY_UID>
Replace <MY_UID> with your own user ID. If you don't know it, you can use the following linux command to find it:
id -u
The UID parameter is used to create an internal container user that has the same permissions as your current user.
Use sudo docker run -it xshill/arm to launch the container. This will drop
you in an interactive bash session where you can use the tools. The working directory is /work.
You will most likely
want to access files that are outside of the container. To achieve this, you can use the -v flag to create a volume (a folder shared between your host and your container). For example:
sudo docker run -it -v /tmp/my_arm_files:/work xshill/arm
This will create a container with a link from the /work folder in the container to the /tmp/my_arm_files folder on the host.
The following aliases are available to the container user:
cc: compile program for ARM using gcccchf: compile program for ARMHF using gccrun: run ARM programs using qemurunhf: run ARMHF programs using qemu
