# build_audiod.sh — meow_audiod 交叉编译（mipsel 静态）+ 宿主多目标可选。
#
# 目标：R3 Pro II / MeowOS（mipsel-linux-muslsf，静态）。audiod 复用 meow_ipc.h（共享协议头，
# -I../meow_launcherd）。audiod 为 svcd 托管的独立守护；meow_audio 为用户侧 CLI。
#
# 用法：
#   ./build_audiod.sh            # 交叉编译 → meow_audiod（mipsel 静态）
#   ./build_audiod.sh cli        # 交叉编译 meow_audio CLI → meow_audio（mipsel 静态）
#   ./build_audiod.sh host       # 宿主编译 meow_audiod_host + meow_audio_host（集成测试）
