ARM64 Builds

[lewis262626]

Is your feature request related to a problem? Please describe.
I'd like Spotifyd to include a Linux ARM64 build. I can currently work around this by installing the 32-bit C libraries but I'd prefer a native 64bit build.

I'm running on Raspbian Buster on a Raspberry Pi 4B+.

Describe the solution you'd like
GitHub actions to test, build and release a Linux ARM64 build

Describe alternatives you've considered
You can get Spotifyd working using the armv6 or armhf builds and installing the nesseccary C libraries through your package manager, but this requires installing extra dependencies just for one program. I'd like Spotifyd to run out of the box on the 64bit Raspberry PIs

dpkg --print-architecture
arm64

readelf -a spotifyd | grep interpreter:
      [Requesting program interpreter: /lib/ld-linux-armhf.so.3]

This is also useful if you want to run a docker container on an mac M1 or later, because they also use ARM64 and so the docker containers built for linux/arm64 work better.

What is armhf anyway? Is that the linux/arm64? does the linux armhf tarball have a working binary for this use case?

Armhf stands for Arm32 *hard float *. Hard float meaning hardware support for floating point calculations. So, yep you can run armhf on an arm32 Linux but you've got to install loads of arm32 packages such as libc etc.

Apple devices can use Docker like you said or Rosetta

Thank you very much for your help in understanding 🙏

I don't know if anyone is interested, but if it helps, I wrote this small Dockerfile to produce a linux/arm64 debian package. I'll just post it here in case anyone needs it for this or any other rust project:

# this file is just a rust builder for ARM
FROM --platform=linux/arm64/v8 rust:slim-bookworm

# this could be any rust repo
ENV RUST_REPO="https://github.com/Spotifyd/spotifyd.git"
# all the prereq packages you need to install, separated by spaces
ENV APT_PKGS="libasound2-dev libssl-dev libpulse-dev libdbus-1-dev"

# install prereqs for spotifyd and install cargo-deb for making debian packages
RUN apt update && \
    apt install -y --no-install-recommends git $APT_PKGS && \
    cargo install cargo-deb

# # clone the rust repo
RUN git clone $RUST_REPO /app

WORKDIR /app

# build the rust package and copy it to /
RUN cargo deb && \
    cp ./target/debian/*.deb /

To just run the docker container and get the spotifyd_0.3.5_arm64.deb out of it, you can do:

# build the docker image, but you could also grab the code from this file and do a multistage build
docker buildx build --platform=linux/arm64 -t rustbuilder:spotifyd-dev .

# this creates the docker image and copies the deb to your current directory before cleaning up the container
docker cp $(docker create --name rustemp rustbuilder:spotifyd-dev):/spotifyd_0.3.5_arm64.deb . && docker rm rustemp

and installing the nesseccary C libraries through your package manager

@lewis262626 any chance you'd be willing to elaborate for a *nix n00b (me)?

I've got a Pi4B and some other apps I suspect would benefit from the 64-bit OS, but I'd hate to lose Spotify.

@jessebot Awesome, thank you for the instructions!

Just in case anyone has problems extracting the .deb file in the last step: I needed to replace spotifyd_0.3.5_arm64.deb by spotifyd_0.3.5-1_arm64.deb .
