1To build tcpdump under Windows, you need:
2
3- version 6 (or higher) of Microsoft Visual Studio or the Cygnus gnu 
4C compiler.
5- The November 2001 (or later) edition of Microsoft Platform 
6Software Development Kit (SDK), that contains some necessary includes 
7for IPv6 support. You can download it from http://www.microsoft.com/sdk
8- the WinPcap source code, that includes libpcap for win32. Download it
9from http://winpcap.polito.it or download libpcap sources from
10http://www.tcpdump.org and follow the instructions in the README.Win32
11file.
12
13First, extract tcpdump and WinPcap in the same folder, and build WinPcap.
14
15The Visual Studio project and the cygwin makefile are in the Win32\prj
16folder.
17
18From Visual Studio, open windump.dsw and build the program. The release 
19version of the WinDump.exe executable file will be created in the 
20windump\win32\prj\release directory . The debug version will be generated
21in windump\win32\prj\debug.
22
23From cygnus, go to windump\win32\prj\ and type "make". WinDump.exe will be
24created in the same directory.
