13. Apple Silicon macOS¶

Warning

Experimental targets cannot be used in safety-critical contexts, and there is no guarantee that the Ferrocene test suite is successfully executed on the target. They are provided as a preview, with limited support available. They should not be used in production.

The aarch64-apple-darwin Ferrocene target provides support for macOS (Darwin) on Apple Silicon.

13.1. Prerequisites¶

This target uses the LLVM ld.lld linker. In order to locate the system C libraries required to link a functional macOS binary, this target drives the ld.lld linker using your system’s C compiler as a linker driver.

Install one of:

Xcode command line tools, or
Xcode

Note

If using Xcode, you will require an Apple Developer Program membership.

Xcode command line tools can be installed via xcode-select:

xcode-select --install
