Description

Fresh Linux source builds with visualization enabled can fail inside GLFW because the documented prerequisites omit libxkbcommon-dev. Check xkbcommon>=0.5.0 in the shared Wayland preflight and report the package in the existing combined installation command.

Document the GLFW development packages and point OAK, Wuji, LeRobot, and camera source-build setup at the shared prerequisites.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Testing

• Isolated CMake/pkg-config checks: installed, missing, too-old, Wayland/viz disabled, missing pkg-config, non-Linux, and retry after the dependency becomes available.
• Real top-level configure with xkbcommon hidden: actionable failure before GLFW fetching.
• make -C docs current-docs, shell syntax check, and all pre-commit hooks with the CI skip.
• No new test suite; exercised the existing preflight directly. Device hardware regressions remain for QA.

Checklist

• I have read and understood the contribution guidelines
• I have run the linter and formatter with SKIP=check-copyright-year pre-commit run --all-files
• I have made corresponding changes to the documentation
• I have added tests that prove my fix/feature works (or explained why not)
• I have signed off all my commits (git commit -s) per the DCO

Summary by CodeRabbit

• Bug Fixes

  • Linux visualization builds using GLFW’s Wayland backend now check for xkbcommon 0.5.0 or newer and report it when missing.

• Documentation

  • Updated source-build prerequisites and installation guidance for Linux visualization and related features.
  • Clarified setup steps for OAK cameras, Wuji Gloves, and SO-101 Leader plugin builds, including the required Linux format-checking tool.
  • Directed camera visualization installation guidance to the shared build-prerequisites documentation.

Walkthrough

The build preflight now checks for xkbcommon >= 0.5.0 when BUILD_VIZ enables GLFW’s Wayland backend and PkgConfig is available. The source-build instructions list this prerequisite and related Ubuntu development packages. The OAK, Wuji Glove, SO-101 Leader, and camera visualization instructions now refer readers to shared setup documentation.

Merge Risk: Low · up to 2ba4c

Most builds remain unaffected, but some Wayland setups require an avoidable additional configure cycle.

Full details: Title check

Explanation

The title "build: preflight xkbcommon and document GLFW prerequisites" matches the main changes: the CMake preflight now requires xkbcommon>=0.5.0 when the Wayland backend is enabled, and the docs now list GLFW prerequisites and point source-build entry points to the shared prerequisites page. It is specific, concise, and follows a conventional commit style. Minor detail omitted: the title does not mention the Ubuntu install command update, which is part of the documentation change but not the main point.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files. (5 skipped: 5 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Line 56: Update the PkgConfig_FOUND guard in the build-dependency check so a
missing pkg-config does not prevent xkbcommon from being included in the
generated install command; probe xkbcommon without pkg-config or conservatively
add libxkbcommon-dev when pkg-config is absent.
