# FILE:  scripts/build-board.sh
# DESC:  把源码同步到目标板卡 (RK3588 / Ubuntu 22.04)，在板卡原生编译
#        （aarch64 直编，比本地 QEMU 模拟快约 10 倍），并把产物部署到
#        /root/work/h100/bin/，可选重启 systemd 服务。
#
# 用法:
#   ./scripts/build-board.sh                       # 同步+编译+部署（不重启）
#   ./scripts/build-board.sh --start               # 编译后重启 3 个服务
#   ./scripts/build-board.sh --clean               # 板卡上重新 cmake 再编译
#   ./scripts/build-board.sh --jobs 4              # 指定并行度（默认板卡 nproc）
#
# 参数:
#   --host <ip>      目标主机（默认 192.168.0.223）
#   --user <user>    登录用户（默认 root）
#   --board-src <dir> 板卡源码目录（默认 /root/work/h100/src）
#   --board-bin <dir> 板卡部署目录（默认 /root/work/h100/bin）
#   --jobs <n>       编译并行度（默认板卡 nproc）
#   --start          编译部署后重启服务
#   --clean          先重新 cmake（配置变更时用）
#   -h, --help       显示帮助
#
# 前置: 板卡已配免密 SSH，且有编译环境（cmake/g++/MOOS/jsoncpp），
#       源码已能本地编译（本脚本只负责同步+板卡编译）。
