Header-only(?)

Most Boost libraries are header-only: they consist entirely of header files containing templates and inline functions, and require no separately-compiled library binaries or special treatment when linking.

版本 boost_1_88_0
测试环境 Ubuntu 24.04 (WSL 2) 非root 当然gcc/g++肯定是必需的

使用Header-only的库
下载代码解压后，在Include Path中添加：/some_path/boost_1_88_0/；或者使用：-I/path/to/boost_1_88_0

使用需要编译的库

./bootstrap.sh # 配置构建工具
 
./b2 # 全部编译
# 可以附加参数（--with-filesystem --with-system等）指定需要编译的模块
 
# 编译后的提示（按照指示配置即可）
...
The following directory should be added to compiler include paths:
 
    /home/zh-ge/boost_1_88_0
 
The following directory should be added to linker library paths:
 
    /home/zh-ge/boost_1_88_0/stage/lib
 
# 查看编译结果（静态库和动态库都是有的）

# 没有问题，可以安装（只是不好控制版本）
sudo apt update
sudo apt install libboost-all-dev
 
# 安装后的结果
zh-ge@DESKTOP-3UMDA4O:~$ apt list | grep 'boost'

Header-only 的部分肯定是直接编译到最终的程序中去了

g++ main.cpp -o my_program \
    -I~/boost_1_88_0 \
    ~/boost_1_88_0/stage/lib/libboost_system.a \
    ~/boost_1_88_0/stage/lib/libboost_filesystem.a

如果不设置环境变量的话，运行时可能找不到 .so（动态库）

g++ main.cpp -o my_program \
    -I~/boost_1_88_0 \
    -L~/boost_1_88_0/stage/lib \
    -lboost_system -lboost_filesystem
 
# 添加环境变量
export LD_LIBRARY_PATH=~/boost_1_88_0/stage/lib:$LD_LIBRARY_PATH
