rust 1.84 + cross compiling to aarch64-apple-darwin results in curl linker error

[astelmashenko]

Hello, I't trying to cross-compile my cli tool from linux to apple darwin and got into issue, it is the same when I try to build in docker or on my local machine.

OS: linux (dockerhub rust:latest)
Rust/Cargo version: 1.84.0
Zig version (via pip3): ziglang-0.13.0.post1
cargo-zigbuild: v0.19.7

I run cargo zigbuild --target aarch64-apple-darwin and get the next error:

error: linking with `/root/.cache/cargo-zigbuild/0.19.7/zigcc-aarch64-apple-darwin-d40.sh` failed: exit status: 1

Any suggestions how to resolve it? Thanks.

You need to compile a static curl for aarch64 macOS before hand and specific it in RUSTFLAGS, or enable the static-curl feature from curl crate.
