Prebuilts for Apple Silicons (darwin-arm64v8)

[chengluyu]

Hi, is there any plan to add prebuilts for darwin-arm64v8?

Yes, it is dependent on a CI provider making Apple Silicon M1 hardware available for free to open source projects. If anyone knows of one please add a comment (or better yet a PR to integrate with it).

Please see lovell/sharp#2460 for some discussion about how to compile libvips from source on this new platform.

Thanks a lot! I should search in lovell/sharp first. I'm leaving this issue open. Feel free to close it.

I think you could also cross-compile for aarch64-apple-darwin on a x86_64-apple-darwin machine (or even on x86_64-unknown-linux-gnu). Note that dependencies built upon Rust (i.e. librsvg) require Rust to be installed via the beta channel, as Apple Silicon support only recently landed in Rust/Rustup. Perhaps we should wait for Rust 1.49 before considering this approach.

In an happy coincidence, I actually worked on this today: #74 (very wip, probably unmergable in its current state due to the maintenance cost)

Ran into some libffi trouble (which was quite expected) as the python build script is bugged

librsvg can be worked around by using an older version. As detailed in the PR, macports did exactly that.

sharp v0.28.0 is now available and provides prebuilt libvips binaries for darwin-arm64v8. Merci beaucoup for your help @abarisain!

Great! Thanks everyone!
