Boost library study notes (1) Installation and configuration

Boost库学习笔记（一）安装与配置

1. 获取boost

https://www.boost.org/users/history/version_1_79_0.html

任选其一

boost的目录结构：

tip：

1. boostLibrary the root directory of the library should set the environment variable**$BOOST_ROOT** 中,笔者路径为（D:\Software\boost_1_79_0）
2. 编译boost程序时,你需要将boostThe header file directory added,笔者路径为（D:\Software\boost_1_79_0\boost）

Only the header file library：

大多数的boost库都是header-only的,The header file already contains templates and inline function,Don't need separate compilation or special treatment when link.

Of course there are some libraries need to separate compilation to use：

There are a few is optional separate compilation：

• Boost.Graph also has a binary component that is only needed if you intend to parse GraphViz files.
• Boost.Math has binary components for the TR1 and C99 cmath functions.
• Boost.Random has a binary component which is only needed if you’re using random_device.
• Boost.Test can be used in “header-only” or “separately compiled” mode, although separate compilation is recommended for serious use.
• Boost.Exception provides non-intrusive implementation of exception_ptr for 32-bit _MSC_VER==1310 and _MSC_VER==1400 which requires a separately-compiled binary. This is enabled by #define BOOST_ENABLE_NON_INTRUSIVE_EXCEPTION_PTR.
• Boost.System is header-only since Boost 1.69. A stub library is still built for compatibility, but linking to it is no longer necessary

2.Windows安装过程

使用windowsThe command prompt with administrator permissions to open,切换到boost的根目录.

bootstrap.bat  # 执行bootstrap.bat的批处理
# 运行完成后会生成b2.exe程序
b2.exe # 开始编译工作

b2.exeProgram can support parameters are：

• toolset 编译器类别,可以是gcc,或者是msvc

• target-os 目标操作系统,可以是Windows,Linux

• variant 生成类型,可以是 debug（-gd-）或者release (-)

• threadapi 线程API的实现,可以是win32或者pthread,在windows上编译就用win32

• link 链接库类型,可以是静态的static,也可以是shared,对应windows上的库就是.lib或者是dll

• runtime-link 动态还是静态链接C/C++运行时库.同样有shared (-)和static (-s-)两种方式,这样runtime-link和link可以产生4种组合方式,可以根据需要选择编译.

• prefix 安装路径

• user-config 用户自定义配置文件,在cross compile的时候可以用来配置编译工具链

• address-model 生成32位还是64位库文件

• architecture=x86 cpu架构,一般台式机位x86,嵌入式平台位arm

编译安装64位的Release版的静态链接库可以执行下面的指令：(-mt-s-)

.\b2.exe variant=release threading=multi threadapi=win32 link=static runtime-link=static --prefix=E:\boost_1_77_0 address-model=64 architecture=x86 install -j8

From this paragraphhttps://www.cnblogs.com/lylygoing/p/BoostDownload.html

当没有指定参数的时候,The default compiler generated in the current directory.

从输出可以看出,头文件在D:\Software\boost_1_79_0,The path of the link libraries inD:\Software\boost_1_79_9\stage\lib下,Which also would generatebin.v2的目录,大小在2.3G左右,可以直接删除.

3. Linux安装过程

• 下载
  https://www.boost.org/users/history/version_1_79_0.html
  

  tar -xzvf boost_1_79_0.tar.gz #解压
  cd boost_1_79_0 #进入目录
  vim bootstrap.sh #修改prefix为指定目录,笔者为/usr/local/boost1.79
  ./bootstrap.sh
  sudo ./b2 install # 不加sudoStill generated in this directory
  

4.VSThe compilation of prepared

• 创建新项目（VS2022）

  
  

• 新建一个源文件
  
  

  粘贴以下代码

  #include <boost/lambda/lambda.hpp>
  #include <iostream>
  #include <iterator>
  #include <algorithm>
  
  int main()
  {
        
      using namespace boost::lambda;
      typedef std::istream_iterator<int> in;
  
      std::for_each(
          in(std::cin), in(), std::cout << (_1 * 3) << " ");
  }
  

• The solution configuration
  

  

  

5.测试运行

Every time the output you input values three times

6.要点总结

1. To install, perform beforebootstrap的脚本文件（Windows执行.bat,Linux执行.sh）,之后再执行b2Program compiles the installation,Pay attention to the parameters can be specified.
2. 使用BoostIf master additional the header files and libraries directory,What kind of tools are to follow the principle of the.
