#!/bin/bash
# build_launcher.sh — MeowOS launcher (A-1/A-2: launcher 用 SDK 渲染栈).
#
# 变更点（相对 M2.27 / A-0）：
#   - launcher 不再自建 back_buf/meow_present/refresh_governor —— 改用 SDK 渲染栈：
#     fb 指向 SDK 的 back_buf（meow_ui_back_buf），呈现统一 meow_ui_flush()（SDK present，
#     内含 vsync + 帧率门控 + 原子 blit 脏区）；刷新率档位经 meow_ui_set_refresh_rate()/
#     set_refresh_always_max() 交给 SDK（归口 PERF_SCHEDULER 显示子域）。
#   - 播放器 fb 双缓冲交互（fb_backup_player/fb_norm_buf0/fb_restore_player/FBIOPAN/yoffset）
#     保留不动（与 present 上屏不同层）。
#   - launcher 与 SDK 共用同一 meow_font.o（已打进 meow_ui.a）——不再单独链 meow_font.a。
#   - MEOWOS_VERSION 0.7.21 → 0.7.23（M2.28）。
#
# 用法（在 patch_v2/meow_launcherd 下或任意目录）：
#   bash build_launcher.sh         # 交叉编译 meow_launcherd（mipsel 静态）
#   bash build_launcher.sh test    # 宿主 gcc 跑本目录 affected 单测（test_bt_page / test_netmgr_ipc）
#
# 工具链：优先环境变量 ZIGCC / MIPS_SYSROOT（M47 起），否则退回历史固定路径 $HOME/Project/R3ProII。
#   export ZIGCC=$HOME/.tools/zig-mipsel-cc
