rk3568build-linux.sh解析

---

前言

正点原子rk3568学习笔记，rk官方RKNN_MODEL_ZOO文件中的build-linux.sh脚本解析

执行命令：./build-linux.sh -t rk3568 -a aarch64 -d mobilenet

解析

#!/bin/bash

指定脚本的解释器为/bin/bash，即使用Bash shell来执行此脚本。

set -e

如果脚本中的任何命令执行失败（返回非零退出状态），则立即退出脚本执行。这有助于捕获错误。

echo “$0 $@”

$ 0是脚本的名称，$ @是所有传递给脚本的参数。这行命令会打印出脚本名称及其接收到的所有参数。

while getopts ":t:a:d:b:m:r:j" opt; docase $opt int)TARGET_SOC=$OPTARG;;a)TARGET_ARCH=$OPTARG;;b)BUILD_TYPE=$OPTARG;;m)ENABLE_ASAN=ONexport ENABLE_ASAN=TRUE;;d)BUILD_DEMO_NAME=$OPTARG;;r)DISABLE_RGA=ON;;j)DISABLE_LIBJPEG=ON;;:)echo "Option -$OPTARG requires an argument." exit 1;;?)echo "Invalid option: -$OPTARG index:$OPTIND";;esac
done

使用getopts命令解析命令行选项，类似与for和switch case。脚本支持的选项包括-t（目标SOC），-a（目标架构），-d（构建演示名称），-b（构建类型），-m（启用ASAN），-r（禁用RGA），-j（禁用libjpeg）。根据选项的不同，设置相应的变量。
TARGET_SOC = rk3568
TARGET_ARCH = aarch64
BUILD_DEMO_NAME = mobilenet
