qbz-ui's Slint build imports the lyrics fonts from the repo root (../../../../static/fonts/*.ttf), which is outside the crates/ workspace cross mounts — so the cross build couldn't find them. Mount static/ at its host path via CROSS_CONTAINER_OPTS. cc

# build-aarch64-linux.sh — build the Linux aarch64 (ARM64) `qbz` binary, e.g.
|
|
# for a Raspberry Pi 4 / other ARM single-board boxes.
|
|
#
|
|
# ── READ FIRST: where can this run? ──────────────────────────────────────────
|
|
# The generated Slint crate `qbz_ui` compiles as ONE ~1.6M-line module whose
|
|
# single `rustc` needs ~30 GB RAM (RSS+swap). Consequences:
|
|
# • An 8 GB Mac or a 4 GB Pi CANNOT build it natively — it OOMs. Don't try.
|
|
# • Build on a box with >= ~16 GB RAM + swap (the wall is survivable at
|
|
# ~14 GB RAM + swap, proven on the dev box).
|
|
#
|
|
# This script has two modes, auto-selected by the host arch:
|
|
#
|
|
# 1. NATIVE (running ON aarch64 Linux: an ARM runner, an ARM VM, etc.)
|
|
# -> apt-installs the build deps and runs `cargo build --release -p qbz`.
|
|
# This is exactly what a future Slint aarch64 CI job runs — treat the
|
|
# dep list + build line below as the workflow's source of truth.
|
|
#
|
|
# 2. CROSS (running on x86-64 Linux with Docker, e.g. the dev box, 30 GB)
|
|
# -> uses `cross` (https://github.com/cross-rs/cross): a container with
|
|
# the aarch64 sysroot + the arm64 dev libs (see crates/Cross.toml) does
|
|
# the compile. Needs Docker running and ~30 GB RAM available to it.
|
|
#
|
|
# macOS is intentionally NOT a build host here: cross from macOS to
|
|
# linux-gnu means re-creating a full Linux sysroot for every native dep
|
|
# (ALSA, dbus, fontconfig, …). Run the CROSS mode on a Linux box instead.
|
|
#
|
|
# Output: dist/qbz-aarch64-linux (an aarch64 ELF — verify with `file`).
