在编译和运行环境的设置上，本文使用以下工具和版本：
ubuntu-1804（x86_64）qca-IPQ6018，支持arm和arm64，基于openwrt系统本文将逐步解释以下内容：
编写本地程序："
指定toolchain，交叉编译：
多级文件如何定义、生成Makefile相关文件：
autoscanf：用于生成configure.scan文件scan文件改名为configure.ac，并对相关内容进行修改aclocal：用于生成aclocal.m4文件autoconf：根据上述M4文件生成configure脚本automake --add-missing命令./configure并编译项目以下是完整的命令列表：
# cmd : autoscanautoscan# cmd : mv configure.scan configure.acmv configure.scan configure.ac# cmd : aclocalaclocal# cmd : autoconfautoconf# cmd : touch Makefile.amtouch Makefile.am# cmd : touch src/Makefile.amtouch src/Makefile.am# cmd : automakeautomake --add-missing# cmd : ./configure./configure
在交叉编译过程中，需要指定以下参数：
# 交叉编译示例./configure --host=arm-openwrt-linux --prefix=/[路径]/toolchain-qca/toolchain-arm_cortex-a7_gcc-5.2.0_musl-1.1.16_eabi
