boost库安装记录

一、下载boost

1. Download .

2. 在boost库安装目录中解压
   tar --bzip2 -xf /path/to/boost_1_79_0.tar.bz2

二、boost发行版

目录结构：

* boost_1_79_0/ .................The “boost root directory”
  * index.htm .........A copy of www.boost.org starts here
  * boost/ .........................All Boost Header files
  *  libs/ ............Tests, .cpps, docs, etc., by library
      *  index.html ........Library documentation starts here
      *   algorithm/
      * any/
      *  array/
         …more libraries…
  *  status/ .........................Boost-wide test suite
  *   tools/ ...........Utilities, e.g. Boost.Build, quickbook, bcp
  *   more/ ..........................Policy documents, etc.
  *   doc/ ...............A subset of all Boost library doc

1. ** $BOOST_ROOT**通常是boost root directory (often /usr/local/boost_1_79_0)
2. 因为所有的boost头文件都有.hpp扩展名，并且位于boost根目录的boost /子目录中，所以boost #include指令可以：
   #include 或
   #include "boost/whatever.hpp"
3. 不要被doc/子目录分心;它只包含boost文档的一个子集。如果您想要查找全部内容，请从libs/index.html开始。

三、构建boost

1、大部分boost不需要构建，是head-only的库。
2、需要编译的库有：

• Boost.Chrono
• Boost.Context
• Boost.Filesystem
• Boost.GraphParallel
• Boost.IOStreams
• Boost.Locale
• Boost.Log (see build documentation)
• Boost.MPI
• Boost.ProgramOptions
• Boost.Python (see the Boost.Python build documentation before building and installing it)
• Boost.Regex
• Boost.Serialization
• Boost.Thread
• Boost.Timer
• Boost.Wave

3、一些库有可选的单独编译的二进制文件：

• 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.

四、示例

#include 
#include 
#include 
#include 

int main()
{
    using namespace boost::lambda;
    typedef std::istream_iterator in;

    std::for_each(
        in(std::cin), in(), std::cout << (_1 * 3) << " " );
}

1. c++ -I path/to/boost_1_79_0 example.cpp -o example
2. echo 1 2 3 | ./example

3. 结果如下：
