windows下编译Libevent

下载最新的libevent，目前是

libevent-2.0.21-stable.tar.gz

修改“D:libevent-2.0.21-stableevent_iocp.c”、“D:libevent-2.0.21-stable evthread_win32.c”、“D:libevent-2.0.21-stablelistener.c”三个文件，在文件开头分别加上一行：

#define _WIN32_WINNT 0x0500

在Makefile.nmake中的CFLAGS中加入/ZI选项,同时去掉/Ox优化选项，这样生成的lib库会带有调试信息

进入VS2010命令提示

切换到libevent的所在目录

nmake /f Makefile.nmake

编译成功生成

libevent.lib、libevent_core.lib、libevent_extras.lib

复制include 和libs

mkdir D:libeventinclude
xcopy /E /H /R D:libevent-2.0.21-stableinclude* D:libeventinclude
xcopy /E /H /R D:libevent-2.0.21-stableWIN32-Code* D:libeventinclude
xcopy /E /H /R D:libevent-2.0.21-stable*.h D:libeventinclude
mkdir d:libeventlibs
copy D:libevent-2.0.21-stable*.lib D:libeventlibs

新建vs2010控制台项目并使用以下代码

// libeventTest.cpp : Defines the entry point for the console application.
//
 
#include "stdafx.h"
/*
 * XXX This sample code was once meant to show how to use the basic Libevent
 * interfaces, but it never worked on non-Unix platforms, and some of the
 * interfaces have changed since it was first written.  It should probably
 * be removed or replaced with something better.
 *
 * Compile with:
 * cc -I/usr/local/include -o event-test event-test.c -L/usr/local/lib -levent

进入配置管理器，设置活动项目为release

C++常规附加包含目录 .include;.includeevent2

代码生成运行库多线程 (/MT)
高级编译为编译为 C 代码 (/TC)

链接器

常规附加库目录 .libs
输入附加依赖项 ws2_32.lib;wsock32.lib;libevent.lib;libevent_core.lib;libevent_extras.lib;%(AdditionalDependencies)
输入忽略特定默认库 libc.lib;msvcrt.lib;libcd.lib;libcmtd.lib;msvcrtd.lib;%(IgnoreSpecificDefaultLibraries)

haven2002标注：不用忽略也没事

include文件夹下面，包含event2文件夹和一堆.h文件即可。用上面的命令，复制了一堆没用的东西。
