安裝boost：

http://www.boost.org/下載boost，我下下來是boost_1_51_0.
boost庫的大部分都可以直接引用頭文件就行了，因為大多數都是頭文件里模板加inline函數構成。但是也有些是需要安裝成二進制lib的，比如thread.（詳見文檔：”Getting Started…”）

$ cd boost_1_51_0 $ sudo ./bootstrap.sh //這條命令類似./configure. 也可以./bootstrap.sh --help看看有哪些命令參數. $ sudo ./b2 install //這樣，boost庫的所有頭文件和需要編譯的lib都安裝到/usr/local/lib 和 /usr/local/include了。（頭文件在boost文件夾里.）

boost擴展工具-線程池(threadpool)：
http://threadpool.sourceforge.net/下載threadpool，然后把threadpool里面的boost目錄下的threadpool.hpp和threadpool文件夾拷貝到/usr/local/include/boost/下(如果有權限問題還得cd /usr/local/include/boost && sudo chmod -R 777 *).
使用threadpool需要鏈接boost的兩個共享庫：boost_thread、boost_system（如果是靜態鏈接那就還得動態鏈接pthread庫）, 并且include

callback_task.hpp:/** @file callback_task.hpp* @brief add callback task for threadpool.*/#ifndef __callback_task_h__ #define __callback_task_h__#include <boost/function.hpp>namespace boost { namespace threadpool {template<class RetType> class callback_task {typedef boost::function<void (RetType)> CALLBACK;typedef boost::function<RetType ()> FUNCTION;private:CALLBACK m_Callback;FUNCTION m_Function;public:callback_task(FUNCTION f, CALLBACK c):m_Callback(c), m_Function(f){}void operator()(){ m_Callback(m_Function()); } };}} // namespace boost::threadpoll#endif // __callback_task_h__
