安装boost：

http://www.boost.org/下载boost，我下下来是boost_1_51_0.

boost库的大部分都可以直接引用头文件就行了，因为大多数都是头文件里模板加inline函数构成。但是也有些是需要安装成二进制lib的，比如thread.(详见文档："Getting Started...")

$ cd boost_1_51_0

$ sudo ./bootstrap.sh //这条命令类似./configure. 也可以./bootstrap.sh --help看看有哪些命令参数.

$ sudo ./b2 install //这样，boost库的所有头文件和需要编译的lib都安装到/usr/local/lib 和 /usr/local/include了。(头文件在boost文件夹里.)

boost扩展工具-线程池(threadpool)：

http://threadpool.sourceforge.net/下载threadpool，然后把threadpool里面的boost目录下的threadpool.hpp和threadpool文件夹拷贝到/usr/local/include/boost/下(如果有权限问题还得cd /usr/local/include/boost && sudo chmod -R 777 *).

使用threadpool需要链接boost的两个共享库：boost_thread、boost_system(如果是静态链接那就还得动态链接pthread库), 并且include 。(详见文档: "Installing & Using threadpool")

在使用threadpool时，编译会报错：

task_adaptors.hpp:149:28: error: ‘TIME_UTC’ was not declared in this scope。。。

这是因为boost::TIME_UTC has been renamed to boost::TIME_UTC_ in Boost 1.50。修改task_adaptors.hpp自不必说.
