#!/usr/bin/env bash
# build.sh — Clean build of production binary (standard or with UI).
#
# Usage:
#   scripts/build.sh                              # Standard binary
#   scripts/build.sh --with-ui                    # Binary with the UI embedded
#   scripts/build.sh --help                       # Full usage
#   scripts/build.sh --version v0.8.0             # With version stamp
#   scripts/build.sh --arch x86_64                # Force x86_64 build
#   scripts/build.sh CC=gcc-14 CXX=g++-14        # Override compiler
#
# This script is the SINGLE source of truth for building release binaries.
# Used identically in local development and CI workflows.

Usage: scripts/build.sh [--with-ui] [--version V] [--arch ARCH] [VAR=VAL ...]

The canonical production-build entry: identical in local CI, PR CI, dry run
and release. Always a CLEAN build of BUILD_DIR (build/c by default) — the
content-verified compiler cache (ccache via scripts/env.sh) makes repeat
builds fast without ever reusing a stale object: every object is re-derived
from current sources; a cache hit is byte-identical to a cold compile by
construction (CCACHE_COMPILERCHECK=content).

Options:
  --with-ui       Build the web UI as a content-addressed sidecar (needs node).
  --version V     Stamp the version string (release venue passes the tag).
  --arch ARCH     Force target arch (arm64 | x86_64), e.g. under Rosetta.
  -h, --help      This text.

Make passthrough (VAR=VAL, forwarded verbatim):
  CC= CXX=        Compiler override (venues pass their matrix compiler).
  BUILD_DIR=      Build in an isolated directory — REQUIRED when a clean
                  product build must not wipe build/c's test-runner (e.g.
                  build/smoke for the local ladder smoke).
  STATIC=1        Fully static portable build (Alpine/musl leg).
  EXTRA_CFLAGS= EXTRA_LDFLAGS=   Sanitizer soak builds (see _soak.yml).

Environment:
  CBM_NO_CCACHE=1  Disable the compiler cache (build correctness is identical;
                   only speed changes).

Callers: _build.yml (all release artifacts) · pr.yml pr-smoke · every
docker-compose build/smoke service · win.sh build (Windows VM ladder).
