Cross.toml

# cross-rs configuration — cross-compile linux-aarch64 from x86_64 runners.
# The ubuntu-*-arm hosted runners on GitHub Actions have been chronically
# unstable (runner-shutdown signals before the build even starts), so we
# build the aarch64 artifact inside a Docker container on the x86_64 pool
# instead. The default `ghcr.io/cross-rs/aarch64-unknown-linux-gnu` image
# is based on Ubuntu 22.04 (glibc 2.35) — strictly more compatible than
# the pincab's Ubuntu 24.04 (glibc 2.39) and every supported SBC target.
#
# pre-build pulls all the SDL3/eframe/winit native deps for aarch64 via
# multiarch apt — sdl3-sys's build-from-source-static needs the X/Wayland
# headers at build time even though the resulting binary statically links
# only SDL3 itself.
