#!/usr/bin/env bash
# Cross-build RustyIP for every Linux + Windows (GNU) target we can, inside a
# Rust container, placing arch-named binaries in dist/.
#
# Run from the repo root, e.g.:
# podman run --rm --name rustyip-build \
# -e CARGO_TARGET_DIR=/tmp/target -e CARGO_BUILD_JOBS=2 \
# -v "${PWD}:/work" -w /work docker.io/library/rust:1.96 bash build-podman.sh
#
# Toolchain notes:
# * The `ring` crate compiles C, so each cross target needs its libc dev
# headers; we use the `crossbuild-essential-*` meta-packages (which pull
# gcc-<triple> + libc6-dev-<arch>-cross) rather than the bare gcc-<triple>.
# * gcc-multilib (for i686-unknown-linux-gnu) conflicts with the GNU cross
# compilers, so toolchains are installed in two phases.
# * macOS targets are excluded (they require the Apple SDK; build those on a
# macOS host with build.sh).
