windows 7下编译:
编译环境: windows 7 + VS2010
(1)解压libevent到F:libeventlibevent-2.0.21-stable (请根据你的路径做相关修改)
(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:(此处不修改编译通过)
在以下3个文件开头添加“#define _WIN32_WINNT 0x0500”
libevent-2.0.21-stableevent_iocp.c
libevent-2.0.21-stableevthread_win32.c
libevent-2.0.21-stablelistener.c
(4)使用VS命令提示工具编译:
cd/d F:libeventlibevent-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)VS2010下使用lib
新建一个VC++控制台项目:
环境配置:
项目下建一个Lib目录,将上面三个lib文件copy到该目录下。
新建一个Include目录,将F:libeventlibevent-2.0.21-stableinclude下的文件和文
件夹copy到该目录下,F:libeventlibevent-2.0.21-stableWIN32-Code下的文件copy到该目录下,2
个event2目录下的文件可合并一起。

项目属性设置:
VC++目录:
包含目录,添加:F:ProjectsLibeventTestLibeventTestInclude;
库目录,添加:F:ProjectsLibeventTestLibeventTestLib;
C/C++:
代码生成–>运行库:多线程调试 (/MTd)(Debug下),多线程 (/MT)(Release下)
连接器:
输入:ws2_32.lib;wsock32.lib;libevent.lib;libevent_core.lib;libevent_extras.lib;
ws2_32.lib;wsock32.lib;是用来编译Windows网络相关的程序库。
编译,生成!
编译好的libevent lib下载 Libevent2.0.21.rar
这个是很久前跟xsky玩xblog的时候关注的libevent。
自己亲自测试过,也没什么难度,不同平台可能报不同错,根据错误提示做相关修改就行,
(以上源码不同平台需要细微修改。)
现在的环境是Win10 64位 + Vs2015
刚刚下载了最新的libevent-2.0.22-stable
编译成功,这里最关键的就是环境的设置(包含目录,库环境等),遇到问题还是自己多调试吧,编译后的结果如下,因为没有玩xblog程序了,
原本计划为xblog增加功能,个人精力有限,就没有时间研究那么多了,目前主要学习精力放在前端开发,移动web app。(这个教程已经很详细了,
看了下,并且有给测试结果,如果还不会的话,麻烦多搜索下了。)
