# packaging/build.sh — Top-level build orchestrator for smartbotic-vectorapi
#
# Supports two modes:
#   Default:  Docker build targeting Debian 13 (production .debs)
#   --local:  Native build on current system (development/testing).
#             .deb packaging only happens on a Debian-family host; elsewhere
#             (e.g. Void Linux) it compiles and tests only - packages for
#             release always come from the Docker/Debian-13 path.

Usage: packaging/build.sh [OPTIONS]

Build modes:
  (default)            Docker build targeting Debian 13 (production)
  --local              Native compile + tests for current system (development).
                       Builds .debs only on a Debian-family host; on any other
                       distro packaging is refused - use the Docker mode.

Options:
  --install            Install .debs locally after build (--local, Debian host only)
  --skip-tests         Skip building and running the test suite (--local only)
  --deb-revision N     Debian revision suffix (default: 1)
  --rebuild-base       Force rebuild Docker base image
  --no-cache           Build without Docker caches
  --repo               Add packages to local APT repository
  --suite NAME         Distribution suite (e.g., trixie)
  --sync               Add to repo and upload to repository.smartbotics.ai

Environment variables:
  BUILD_JOBS           Parallel build jobs (default: nproc)
  DEB_REPO_DIR         Path to smartbotics-deb-repo (default: /data/dev/smartbotics/smartbotics-deb-repo)
