Provide a 0.19.1 binary for linux_arm64 to be used in containers on Apple Silicon (M1)

[jsynacek]

Quick Summary: Please, provide a binary that can be used in a linux container running on an Apple Silicon (arm64) host.

Currently, the binary asset binary-for-linux-64-bit.gz is usable, but it's really slow and can't be used if elm is specified as a project dependency:

<inside the container>

$ which elm
/usr/local/bin/elm

$ npm run build
...
npm ERR! command sh -c node install.js
npm ERR! -- ERROR -----------------------------------------------------------------------
npm ERR!

Thanks for reporting this! To set expectations:

• Issues are reviewed in batches, so it can take some time to get a response.
• Ask questions in a community forum. You will get an answer quicker that way!
• If you experience something similar, open a new issue. We like duplicates.

Finally, please be patient with the core team. They are trying their best with limited resources.

I just tried to compile the project using docker on a Debian arm64 VM (M1 MacBook) with no luck. I am not familiar with Haskell so I wasn't able to do more

Have you tried installing via nix? That has worked for me on arm64 (pinebook) but not specifically an M1.

@jsynacek if you've not seen it already, I built linux_arm64 binaries and Simon has made them available with @lydell/elm: https://github.com/elm/compiler/pull/2287

[alshdavid]

Any updates to this? :)

[supermario]

@alshdavid you can find linux-arm64 binaries here: https://github.com/lydell/compiler/releases/tag/0.19.1

Is there a way to tell the install script for the elm package not to download the binaries?

https://github.com/elm/compiler/blob/master/installers/npm/download.js#L27

It seems npm install elm will fail when running on Linux arm, even if the binaries are supplied externally, because the script will fail to match the permitted platforms.

@alshdavid If you go to https://github.com/elm/compiler/pull/2287 and scroll to the end of the PR description and expand “Aside about unsupported platforms” you can see how the discussion went about that.
