Under Win32, libpcap is integrated in the WinPcap packet capture system. WinPcap provides a framework that allows libpcap to capture the packets under Windows 95, Windows 98, Windows ME, Windows NT 4, Windows 2000 and Windows XP. WinPcap binaries and source code can be found at http://winpcap.polito.it: they include also a developer's pack with all the necessary to compile libpcap-based applications under Windows. How to compile libpcap with Visual Studio ----------------------------------------- In order to compile libpcap you will need: - version 6 (or higher) of Microsoft Visual Studio - The November 2001 (or later) edition of Microsoft Platform Software Development Kit (SDK), that contains some necessary includes for IPv6 support. You can download it from http://www.microsoft.com/sdk - the latest WinPcap sources from http://winpcap.polito.it/install The WinPcap source code already contains a recent (usually the latest stable) version of libpcap. If you need to compile a different one, simply download it from www.tcpdump.org and copy the sources in the winpcap\wpcap\libpcap folder of the WinPcap distribution. If you want to compile a libpcap source retrieved from the tcpdump.org Git, you will have to create the scanner and the grammar by hand (with lex and yacc) or with the cygnus makefile, since The Visual Studio project is not able to build them. Open the project file winpcap\wpcap\prj\wpcap.dsw with Visual Studio and build wpcap.dll. wpcap.lib, the library file to link with the applications, will be generated in winpcap\wpcap\lib\. wpcap.dll will be generated in winpcap\wpcap\prj\release or winpcap\wpcap\prj\debug depending on the type of binary that is being created. How to compile libpcap with Cygnus ---------------------------------- To build wpcap.dll, cd to the directory WPCAP/PRJ of the WinPcap source code distribution and type "make". libwpcap.a, the library file to link with the applications, will be generated in winpcap\wpcap\lib\. wpcap.dll will be generated in winpcap\wpcap\prj. Remember, you CANNOT use the MSVC-generated .lib files with gcc, use libwpcap.a instead. "make install" installs wpcap.dll in the Windows system folder.
