fi流程 设置导出环境变量 make-targets | make-usage 参数的执行分支 创建输出目录软连接redme等 获取支持的命令 CMDS$(run_build_hooks support-cmds all | xargs)
通过调用run_build_hooks 并传入参数support-cmds all 最后输出通过xargs处理赋值给CMDS
这个字符串包含了所有支持的命令或选项。遍历选项 help | h | -h | --help | usage 等调用 usage 输出帮助shell | cleanall如果选项是shell或cleanall则执行一段检查代码确保这些选项不是与其他选项组合使用的。如果是单独使用即$opt等于$OPTIONS则跳出循环否则显示错误信息。post-rootfs如果选项是post-rootfs则检查它是否是第一个选项并且后面跟着一个目录参数。如果是将OPTIONS设置为post-rootfs并跳出循环否则显示错误信息。*对于所有其他选项使用option_check函数检查它们是否在$CMDS中定义的支持命令列表中。如果是则继续循环否则显示错误信息。 日志相关 初始化 加载配置环境变量等 设置环境变量处理特殊命令等 输出显示最终配置信息 开始构建最终进入run_build_hooks 传入参数 build debian run_build_hooks 函数 匹配分支 init | pre-build | make-* | usage | support-cmds日志记录调用 run_hooks device/rockchip/common/build-hook debian run_hooks 调用device/rockchip/common/build-hook 下面的sh文件

流程
cp 跟文件系统的库制作交叉编译环境制作交叉编译配置文件配置编译qt并cp到跟文件系统
mk-image.sh

运行2个 post-build.sh制作打包跟文件系统
post-build.sh
后续的配置信息
文件系统的挂载信息修改添加执行 device/rockchip/common/post-hooks 下的sh启动一些服务 02-usb.sh05-udev.sh06-async-commit.sh10-os-release.sh20-info.sh30-fstab.sh40-busybox-reboot.sh50-locale.sh60-dirs.sh90-overlay.sh95-partitions.sh99-owner.sh
大致流程
编译安装必要库drmnpu等 进入文件系统然后gtp命令安装 然后cp ln等qt编译安装文件系统制作
系统制作步骤 解压 debian原始根文件系统 sudo tar -xpf linaro-bullseye-alip-20240903-1.tar.gz 获取文件系统大小然后300 sudo du -sh -m ./binary | cut -f1创建文件 dd if/dev/zero oflinaro-rootfsxw.img bs1M count0 seek2385写入内容并格式化ext4 sudo mkfs.ext4 -d ./binary linaro-rootfsxw.img
