4.3　构建Packet.dll库

构建Packet.dll库的源代码在packetNtx\dll\目录下，要求在Microsoft Visual Studio 2005 SP1版本的环境中构建。我们采用Microsoft Visual Studio 2005构建，同时不需要对AirPcap适配器的支持。

在Microsoft Visual Studio 2005环境中打开E:\winpcap\packetNtx\Dll\Project\目录下的Packet.sln工程，选择Release配置构建Packet.dll库，如果为了调试也可以选择Debug配置。

选择Release配置，开始构建，在Microsoft Visual Studio 2005中执行[Build]→[Rebuild Packet]菜单命令，结果如下：

1＞———Rebuild All started:Project:Packet,Confguration:Release Win32———

1＞Deleting intermediate and output fles for project'Packet',confguration'Release|Win32'

1＞Compiling…

1＞win_bpf_flter.c

1＞Packet32.c

1＞e:\winpcap\Common\packet32.h(53):fatal error C1083:Cannot open include fle:'airpcap.h':No such fle or directory

1＞NpfImExt.c

1＞AdInfo.c

1＞e:\winpcap\Common\packet32.h(53):fatal error C1083:Cannot open include fle:'airpcap.h':No such fle or directory

1＞Build log was saved at"file://e:\winpcap\packetNtx\Dll\Project\Release\x86\BuildLog.htm"

1＞Packet-2 error(s),0 warning(s)

==========Rebuild All:0 succeeded,1 failed,0 skipped==========

从上面的结果中可以看出，编译出错，无法打开airpcap.h文件，此处不需要支持AirPcap适配器，所以在文件packet32.h的第50行添加#undef HAVE_AIRPCAP_API，再重新构建，执行结果如下：

1＞———Rebuild All started:Project:Packet,Confguration:Release Win32———

构建成功，在E:\winpcap\packetNtx\Dll\Project\Release\x86下生成Packet.dll与Packet.lib文件。
