0. 环境、内容、汇总、自动部署脚本

1. 编译环境

在编译和运行环境的设置上，本文使用以下工具和版本：

编译环境：ubuntu-1804（x86_64）

运行环境：qca-IPQ6018，支持arm和arm64，基于openwrt系统

2. 文章内容

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：

3. 汇总步骤

1. 步骤汇总

autoscanf：用于生成configure.scan文件

修改配置文件：将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

新增Makefile.am文件：定义生成Makefile的规则

生成Makefile.in文件：使用automake --add-missing命令

编译、执行：运行./configure并编译项目

2. 命令汇总

以下是完整的命令列表：

# cmd : autoscan
autoscan
# cmd : mv configure.scan configure.ac
mv configure.scan configure.ac
# cmd : aclocal
aclocal
# cmd : autoconf
autoconf
# cmd : touch Makefile.am
touch Makefile.am
# cmd : touch src/Makefile.am
touch src/Makefile.am
# cmd : automake
automake --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

4. 多级文件生成Makefile

工程文件结构

.
├── bin/
├── include/
│   └── common.h
└── src/
    ├── func.c
    └── main.c

步骤汇总

修改配置文件：更新configure.ac中的AC_CONFIG_SRCDIR和AC_OUTPUT命令

在子目录中定义Makefile.am文件：分别为bin/和src/目录下创建Makefile.am

编译并生成文件：使用automake工具进行编译

5. 自动部署脚本

操作步骤

将以下脚本内容复制到编译环境并赋予执行权限

指定一个文件夹名并执行脚本

脚本源码

#!/bin/sh
# Liam
# 20210524
# GPL Version 3
# 1. 检查环境和命令
# 2. 创建项目并初始化源代码
# 3. 执行autoscan并修改配置文件
# 4. 执行aclocal、autoconf
# 5. 创建Makefile.am文件并生成Makefile.in
# 6. 编译和运行
