docs: use cargo-zigbuild for aarch64 cross-compilation#43
Merged
Conversation
Replace the `cross` (Docker-based) cross-compile instructions with `cargo zigbuild`, which uses Zig as the linker and needs no Docker. This removes the "must run from a Docker-mountable path" restriction, so builds work directly from /Volumes/... checkouts. Pin glibc 2.31 to match Raspberry Pi OS bullseye/bookworm.

What
Replace the Docker-based
crosscross-compile instructions inCLAUDE.md(Build + Deploy sections) withcargo zigbuild.Why
cargo zigbuilduses Zig as the linker and needs no Docker, which removes the previous "must run from a Docker-mountable path (NOT/Volumes/)" restriction — builds now work directly from any checkout, including/Volumes/.... The glibc suffix (.2.31) pins the target ABI to cover Raspberry Pi OS bullseye/bookworm.Verified working: built current
mainthis way (~16s, no Docker) and deployed the resulting aarch64 binary to the live gateway successfully.Notes
cargo install cargo-zigbuild+ a Zig toolchain (brew install zig).🤖 Generated with Claude Code
