windows下編譯及使用libevent

Libevent官網：http://libevent.org/

windows 7下編譯：

編譯環境： windows 7 + VS2010

（1）解壓libevent到F:\libevent\libevent-2.0.21-stable

（2）開啟Microsoft visual studio 2010命令列工具

（3）修改以下三個檔案，添加宏定義：

在以下3個檔案開頭添加“#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命令提示工具編譯：

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

nmake /f Makefile.nmake

（5）編譯結果：

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

建立一個VC++控制台項目：

環境配置：

項目下建一個Lib目錄，將上面三個lib檔案copy到該目錄下。

建立一個Include目錄，將F:\libevent\libevent-2.0.21-stable\include下的檔案和檔案夾copy到該目錄下，F:\libevent\libevent-2.0.21-stable\WIN32-Code下的檔案copy到該目錄下，2個event2目錄下的檔案可合并一起。

項目屬性設定：

VC++目錄：

包含目錄，添加：F:\Projects\LibeventTest\LibeventTest\Include;

庫目錄，添加：F:\Projects\LibeventTest\LibeventTest\Lib;

C/C++：

代碼產生-->運行庫：多線程調試 (/MTd)（Debug下），多線程 (/MT)（Release下）

連接器：

輸入：ws2_32.lib;wsock32.lib;libevent.lib;libevent_core.lib;libevent_extras.lib;

ws2_32.lib;wsock32.lib;是用來編譯Windows網路相關的程式庫。

編譯，產生！
