# 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 Slint desktop `qbz`, whose generated `qbz_ui` crate is
|
|
# ONE ~1.6M-line module needing ~30 GB for a single rustc. `qbzd` is the
|
|
# slint-free column of the workspace: no UI crate, no fonts, no GPU libs. It
|
|
# builds in minutes and fits on modest hardware, so:
|
|
# • a 4 GB Pi CAN build it natively (unlike the desktop binary);
|
|
# • the container caps here are small — no 48 GB swap headroom needed;
|
|
# • the `static/` fonts mount the desktop script needs is irrelevant.
|
|
#
|
|
# 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`).
|
