build-aarch64-linux.sh builds -p qbz-qt natively with the distro's Qt (gated at >= 6.8, the tree's floor; Debian 13 / Ubuntu 25.04 / Fedora 41 qualify), installs rustup when absent, forces one rustc at a time on <= 4 GB boxes, and runs the same offscreen smoke as CI. Its CROSS mode is retired honestly: cxx-qt runs the target Qt's qmake during the build, which cross-rs's Ubuntu 20.04 images cannot do. The qbzd script and Cross.toml keep cross-compiling the daemon, with the Qt-free dep set. cc

# build-aarch64-qbzd.sh — build the Linux aarch64 (ARM64) `qbzd` daemon binary,
|
|
# e.g. for a Raspberry Pi 4 + HiFiBerry/USB DAC streamer.
|
|
#
|
|
# ── Why this is NOT build-aarch64-linux.sh ───────────────────────────────────
|
|
# That script builds the Qt desktop `qbz`, which needs a Qt >= 6.8 with private
|
|
# headers on the build host and cannot be cross-compiled with cross-rs (the
|
|
# target Qt's qmake has to run during the build). `qbzd` is the Qt-free and
|
|
# Slint-free column of the workspace: no UI crate, no fonts, no GPU libs. It
|
|
# builds in minutes on modest hardware and cross-compiles cleanly, so:
|
|
# • a 4 GB Pi CAN build it natively;
|
|
# • CROSS mode via cross-rs + crates/Cross.toml still works here;
|
|
# • the container caps are small.
|
|
#
|
|
# Two modes, auto-selected by host arch (same shape as the desktop script):
|
|
#
|
|
# 1. NATIVE (on aarch64 Linux: the Pi itself, an ARM VM/runner)
|
|
# 2. CROSS (on x86-64 Linux with Docker, via `cross`; crates/Cross.toml
|
|
# supplies the arm64 dev libs inside the image)
|
|
#
|
|
# Output: dist/qbzd-aarch64-linux (an aarch64 ELF — verify with `file`).
