如何将 Rust 应用程序从 macOS x86 交叉编译到 macOS Silicon？

Question

我想将一个 Rust 程序从我的 x86 Mac 交叉编译为一个可以在硅 Mac 上运行的二进制文件，但我无法弄清楚链接。

我有：

x86 Mac 运行宁 macOS 10.15.7 Catalina
A Rust project called riff
cargo 1.51.0 (43b129a20 2021-03-16) 最近使用 rustup
Xcode 版本 12.4 (12D4e)

我想将它编译成一个二进制文件，可以在硅 (ARM) Mac 上运行。这可能是以下之一：

硅专用二进制文件
可以在 Silicon 或 x86 上运行的通用二进制文件

我有tried（通过./release.sh --dry）：

rustup target add aarch64-apple-darwin
cargo build --release --target=aarch64-apple-darwin

结果太长无法粘贴在这里，所以这是一个摘录：

Answer 1

添加适当的目标

rustup target add aarch64-apple-darwin

使用 macOS 11.x SDK 编译代码 ¹:

SDKROOT=$(xcrun -sdk macosx11.1 --show-sdk-path) \
MACOSX_DEPLOYMENT_TARGET=$(xcrun -sdk macosx11.1 --show-sdk-platform-version) \
cargo build --target=aarch64-apple-darwin

这会生成一个单一架构的二进制文件：

file target/aarch64-apple-darwin/debug/riff
target/aarch64-apple-darwin/debug/riff: Mach-O 64-bit executable arm64
