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-stable\event_iocp.c”、“D:\libevent-2.0.21-stable \evthread_win32.c”、“D:\libevent-2.0.21-stable\listener.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:\libevent\include\
xcopy /E /H /R D:\libevent-2.0.21-stable\include\* D:\libevent\include\
xcopy /E /H /R D:\libevent-2.0.21-stable\WIN32-Code\* D:\libevent\include\
xcopy /E /H /R D:\libevent-2.0.21-stable\*.h D:\libevent\include\
mkdir d:\libevent\libs
copy D:\libevent-2.0.21-stable\*.lib D:\libevent\libs\

 新建vs2010控制台项目并使用以下代码

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;.\include\event2

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。
