# build-static.sh — Build statically-linked nirc binaries via cargo-zigbuild
#
# Prerequisites:
#   1. rustup target add x86_64-unknown-linux-musl aarch64-unknown-linux-musl
#   2. pip install cargo-zigbuild  (or: cargo install cargo-zigbuild)
#   3. Install zig:  https://ziglang.org/download/
#
# Usage:
#   ./packaging/build-static.sh          # both targets
#   ./packaging/build-static.sh x86_64   # just x86_64
#   ./packaging/build-static.sh aarch64  # just aarch64
