Build AVR tool chain inside containers

Have a look at Building and Installing the GNU Tool Chain from microchip for upstream documentation.

[WIP] Usage

Keep in mind: This is a work in progress.

The image is currently based on alpine and that means it should be linked with musl. If this affects the avr tool chain, is still unknown to me. Further testing has to be done.

Running the container will result in a newly compiled avr toolchain, provided you mounted a local directory as avr-toolchain inside the container.

Building the container

podman build -t avr_toolchain:latest .

Compiling the toolchain

# run the container while mounting `/avr-toolchain` to a local directory.
podman run -ti -v $(pwd)/avr:/avr-toolchain avr_toolchain:latest

# After the container (sucessfully) exit, you can find the toolchain the
# directory you mounted inside the container.

Using the toolchain

You can use the toolchain inside the container:

podman run -ti --entrypoint /bin/sh \
           -v $(pwd)/avr:/avr-toolchain \
           -v $(pwd):/app \
           avr_toolchain:latest

or you use the toolchain on your local machine if you have a musl installation:

# Add avr binaries to your PATH
export PATH=${PATH_TO_TOOLCHAIN}/bin:$PATH
