Support for darwin-arm64

[kingkong404]

Hey, are there plans to support Apple Silicon?

[lucacasonato]

Yes. But we need support in rusty_v8 first: denoland/rusty_v8#520. To get that working, we need to be able to build and test macos ARM64 binaries on CI. So that means either using QEMU, or waiting for GitHub to support macOS arm64 native runners.

There is also a few bugs within the dependency tree that are also failing to build.

So, we have a few mountains to climb first. But they are working on it! briansmith/ring#1063 and rust has to settle on a triple target for it as well rust-lang/rust#73628

[Zlitus]

When I download the latest x86 binary from here, everything run fine with rosetta2 👍. Waiting for a ARM64 native build, but all good in the meantime.

[frankhale]

Once support is in place for Apple Silicon will it be possible to run on a ARM64 board like Raspberry Pi 4? Or will this require additional work?

[kitsonk]

@frankhale that is issue #1846, they are distinct issues.

[kitsonk]

It is not "sustainable" at the moment and still experimental so we will keep this issue open.

[jimmont]

for anyone wanting apple-silicon support, simply install Rust then

cargo install deno --locked

on my m1 macbook air this results with Finished release [optimized] target(s) in 5m 27s and deno runs as expected

[frankhale]

@jimmont I'm a Rust noob, I've been using cargo build --release and am curious why everyone keeps mentioning to use cargo install deno --locked. What is the difference?

[Dygear]

Looks like that forces rust to ignore the network if it can and cherry pick the exact upstream version requested by the cargo toml lock file.

You can find more about that here. https://doc.rust-lang.org/cargo/commands/cargo-build.html#manifest-options

Great question!

[frankhale]

Thank you @Dygear, I'll check out that doc you mentioned!!!

[balupton]

On https://github.com/denoland/deno/releases there is a deno-aarch64-apple-darwin.zip asset, so seems this can be closed right?

[bartlomieju]

See #8346 (comment)

[lino-levan]

Any update on this? Are we waiting for github/roadmap#528 for a "more sustainable solution"?

[bartlomieju]

Yes, right now it requires manual work on release from the maintainers to provide an M1 build.

[crowlKats]

We now have automated releases for apple silicon, so closing.
