1. 下载

当前版本是1.82，下载链接：
https://boostorg.jfrog.io/artifactory/main/release/1.82.0/source/

2. 安装编译依赖库

本地环境是Ubuntu 22.04，需要安装以下依赖库，部分影响boost相关功能的开启，部分影响编译过程。
本地环境编译AOSP源码，安装过相关依赖库，除了这里列出的可能还需要其他依赖库，可根据提示安装。
sudo apt install icu-devtools libicu-dev libbz2-dev liblzma-dev libzstd-dev python3-dev python2-dev -y

2.1 解压

解压后源码文件夹：

boost_1_82_0$ ls
boost            boost.css      bootstrap.sh  index.html  libs             README.md  tools
boost-build.jam  boost.png      doc           INSTALL     LICENSE_1_0.txt  rst.css
boostcpp.jam     bootstrap.bat  index.htm     Jamroot     more             status

2.2 执行bootstrap.sh脚本，生成b2编译工具

1）执行bootstrap.sh后，源码目录下增加b2和project-config.jam两个文件。
2）b2工具是用来编译和安装boost库。
（1）查看帮助：b2 --help
（2）编译：b2
（3）clean：b2 --clean
（4）安装：b2 install
（5）重新配置编译脚本：b2 --reconfigure
如果编译失败或者过程中发现缺少一些依赖库及boost相关模块，安装依赖库后，需要执行这个命令重新检测依赖并生成编译脚本。

$ ./bootstrap.sh

2.3 编译和安装

1）执行b2命令编译源码，先检测编译依赖，然后根据依赖配置进行编译。
2）成功编译后，安装：b2 install。
默认安装路径为：/usr/local/include/boost 和 /usr/local/lib/

2.4 测试程序

安装后，不用指定include和library path，编译时可自动搜索到。
以下测试程序可用clion或者命令行编译：

$ g++ -o main main.cpp

#include <string>
#include <iostream>
#include <boost/foreach.hpp>int main()
{std::string hello( "Hello, world!" );BOOST_FOREACH( char ch, hello ){std::cout << ch;}return 0;
}

2.5 CMake依赖

在cmake脚本中使用find_package显示引用boost：

find_package(Boost 1.82 REQUIRED COMPONENTS filesystem regex PATHS C:/Boost)
find_package(Boost 1.82 REQUIRED COMPONENTS ALL)
find_package(Boost 1.82 REQUIRED ALL)
