If you encounter the following error, the issue is pcaprub uses a hardcoded path for Winpcap.\u00a0 I downloaded winpcap v4.1.3 and downloaded the dev kit for Winpcap and put it in c:\\WpdPack.\u00a0\u00a0 Additionally, since I use an x64 machine I had to copy the file C:\\WpdPack\\Lib\\x64\\*.lib into C:\\WpdPack\\Lib and then the compilation worked.<\/p>\n
You need pcaprub for things like msf.<\/p>\n
