Build Linux binaries natively instead of with cross by antondlr · Pull Request #10283 · sigp/lighthouse

antondlr · 2026-10-09T09:55:31Z

Issue Addressed

CI builds Linux binaries with cross, which pulls third-party build images (ghcr.io/cross-rs), needs QEMU for arm64 docker images, and broke on the recent cc bump (#10278).

Stacked on the runner PR (#10282).

Proposed Changes

Build each architecture natively on a runner of that architecture, inside a pinned rust:1.99.0-bookworm image (scripts/ci/build-linux.sh).
Use it in release.yml and docker.yml; no cross or QEMU left in CI.
Add a RELEASE_RUNNER_ARM64 repository variable for the arm64 release runner (falls back to free ubuntu-24.04-arm).
Keep the make build-* cross targets for local use and binary-builder.

Additional Info

Concerns:

glibc floor goes up from 2.18 to 2.34. Release tarballs will no longer run on Ubuntu 20.04, Debian 11 or RHEL 8 (Ubuntu 22.04, Debian 12 and RHEL 9 are fine).
Rust is pinned by the image (1.99.0) instead of rustup update stable; bumping is a one-line change in the script.
Needs an arm64 release runner. maxperf runs out of memory on the free 16 GB arm runner; releases need an 8-core / 32 GB arm64 larger runner.
Trust: drops the cross-rs images, adds the Docker Hub official rust image (already used by Dockerfile.reproducible).

Tested on a fork with free runners (run): lighthouse x86_64/aarch64 and lcli aarch64 (release), and lighthouse x86_64 (maxperf, release features) all build natively, and the docker images run.

#10229 set CXX=clang++ in .cargo/config.toml to work around LevelDB's -Wthread-safety probe, but the cross images only ship GCC: x86_64 can't find clang++ and aarch64 uses its target-specific GCC and hits the original bug. Use GCC in cross and pre-seed the probe via a CMake wrapper. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…d Node 24 actions - docker.yml: unstable builds use free GitHub-hosted runners; tag builds use the paid larger runner named by the RELEASE_RUNNER repo variable. - release.yml: Linux builds use RELEASE_RUNNER (free runners on forks). - Drop self-hosted runners and the SELF_HOSTED_RUNNERS toggles. - Pin cross to 0.2.5 and docker/* actions to commit SHAs. - Bump runners to ubuntu-24.04 and actions to Node 24 releases.
