# cross (https://github.com/cross-rs/cross) config for cross-compiling the
# aarch64 `qbz` binary from an x86-64 Linux host. Used by
# scripts/build-aarch64-linux.sh (CROSS mode).
#
# `image` pins a newer Ubuntu (cross 0.2.5's default aarch64 image is Ubuntu
# 16.04 "xenial" — EOL, archived repos, OpenSSL 1.0.2 — which breaks modern
# deps). The :main image is Ubuntu 20.04+. If pulling :main ever fails, the
# alternative is a newer cross itself:
#   cargo install cross --git https://github.com/cross-rs/cross --locked
#
# The image ships the aarch64 toolchain but NOT the native dev libs qbz links
# against, so we add the arm64 multiarch packages in pre-build. PKG_CONFIG_* is
# set so build scripts resolve the :arm64 .pc files.
#
# NOTE: each pre-build entry is a single-line TOML string (backslash line
# continuations are only valid in TOML """multi-line""" strings).
