windows 8下编译：

编译环境： windows 8 + VS2013

（1）解压libevent到D:\libevent\libevent-2.0.21-stable

（2）打开Microsoft visual studio 2010命令行工具

（3）修改以下三个文件，添加宏定义：

在以下3个文件开头添加“#define _WIN32_WINNT 0x0500”

libevent-2.0.21-stable\event_iocp.c

libevent-2.0.21-stable\evthread_win32.c

libevent-2.0.21-stable\listener.c

（4）使用VS命令提示工具编译：

cd/d D:\libevent\libevent-2.0.21-stable

nmake /f Makefile.nmake

（5）编译结果：

libevent_core.lib：All core event and buffer functionality. This library contains all the event_base, evbuffer, bufferevent, and utility functions.

libevent_extras.lib：This library defines protocol-specific functionality that you may or may not want for your application, including HTTP, DNS, and RPC.

libevent.lib：This library exists for historical reasons; it contains the contents of both libevent_core and libevent_extra. You shouldn’t use it; it may go away in a future version of Libevent.

（6）VS2013下使用lib

在工程目录下分别创建include和lib目录。

把libevent解压目录下的所有.h复制到include目录。

把lievent解压目录下的include的event目录复制到include目录。

把libevent解压目录下的WIN32-Code下的event2mulu和tree.h复制到include目录。

把libevent解压目录下编译生成的3个.lib文件(libevent.lib、libevent_core.lib和libevent_extras.lib)复制到lib目录。

// LibeventTest.cpp : 定义控制台应用程序的入口点。//#include "stdafx.h"#include <stdio.h>  #include <iostream>  // libevent头文件  #include <event.h>using namespace std;struct event ev; //事件struct timeval tv; //定时器/*事件处理函数,cb=callback*/void time_cb(int fd, short _event, void *argc){cout << "timer wakeup" << endl;event_add(&ev, &tv);/*重新添加定时器*/}int _tmain(int argc, _TCHAR* argv[]){WSADATA WSAData; /*初始化WINDOWS socket库*/WSAStartup(0x101, &WSAData);struct event_base *base = event_init();//初始化libevent库,相当于初始化一个Reactior,就可以注册事件了.tv.tv_sec = 3; //间隔tv.tv_usec = 0;evtimer_set(&ev, time_cb, NULL);//初始化关注的事件，并设置回调函数//等价于event_set(&ev, -1, 0, timer_cb, NULL);event_add(&ev, &tv);//注册事件 相当于调用Reactor::register_handler()函数注册事件event_base_dispatch(base);//进入消息循环和消息分发return 0;}
