1.下载boost源码：

地址：https://sourceforge.net/projects/boost/files/boost/

3. 编译：

1）解压，cd 到目录

–show-libraries可查看所有库，如下

Building Boost.Build engine with toolset gcc... tools/build/v2/engine/bin.linuxx86/b2

The following Boost libraries have portions that require a separate build
and installation step. Any library not listed here can be used by including
the headers only.

The Boost libraries requiring separate building and installation are:
link.jam: No such file or directory
    - atomic
    - chrono
    - context
    - coroutine
    - date_time
    - exception
    - filesystem
    - graph_parallel
    - iostreams
    - locale
    - log
    - math
    - mpi
    - program_options
    - random
    - regex
    - serialization
    - signals
    - system
    - test
    - thread
    - timer
    - wave

使用 --without-libraries=, , , 逗号隔开去掉不想编译的库，–prefix指定编译后的安装路径
这里去掉了pytho和graph，其他的全部编译

./bootstrap.sh --without-libraries=python,graph --prefix=/home/ubuntu/workplace/asio/boost_lib

生成有 b2 和 bjam ，以及一个 project-config.jam 的文件，修改该文件的一行(指定自己的编译器)：

# Boost.Build Configuration
# Automatically generated by bootstrap.sh

import option ;
import feature ;

# Compiler configuration. This definition will be used unless
# you already have defined some toolsets in your user-config.jam
# file.
if ! gcc in [ feature.values <toolset> ]
{
    using gcc : : /opt/hisi-linux/x86-arm/arm-hisiv500-linux/target/bin/arm-hisiv500-linux-gcc ; 
}

project : default-build <toolset>gcc ;

# List of --with-<library> and --without-<library>
# options. If left empty, all libraries will be built.
# Options specified on the command line completely
# override this variable.
libraries =  --without-python --without-graph ;

# These settings are equivivalent to corresponding command-line
# options.
option.set prefix : /home/fens/workplace/asio/boost_lib ;
option.set exec-prefix : /home/fens/workplace/asio/boost_lib ;
option.set libdir : /home/fens/workplace/asio/boost_lib/lib ;
option.set includedir : /home/fens/workplace/asio/boost_lib/include ;

# Stop on first error
option.set keep-going : false ;

注意：这中间是有空格的，如下图标示的地方：

特别是最后一个分号前是有空格的，要不然会出错。

2）执行 ./bjam 即可，这是编译，创建的 lib 文件默认在 stage 文件夹
3）编译完后，执行 ./bjam install 即进行安装到上面 --prefix指定的目录
编译完成的库文件如下（包括静态版本和动态版本）：

boost库有80%是只需要引用头文件就可以使用的，比较方便
