Hi there..
follow the instructions in the attached readme files to be able to run 
libnet programs on WinXP with MSVS 6.0 Sp6, it is the same like the one in 
the libnet package but more detailed...It only works with me for libnet 
1.1.1 and wpcap developers pack 3.0 beta..
When i tried it with libnet 1.1.2 and wpcap 3.1 beta i got an error building 
the library.. But you can try it and if you succeed tell me how...
Regards, Mustaffa Abu Sedira

Kirby Kuehl [email protected]


Tested Platforms:
Windows 2000 SP4, Windows XP SP1

Tested IDEs:
VC++ 6.0 Service Pack 5
Visual Studio .NET 2003
Visual Studio .NET 2002

Winpcap 3.01 Developers pack: http://winpcap.polito.it/install/default.htm
Platform SDK : http://www.microsoft.com/msdownload/platformsdk/sdkupdate/


1. Extract Libnet tarball. (Probably unnecessary since you are reading 
this.)

2. Download and extract Winpcap 3.0 Beta developer's pack from 
http://winpcap.polito.it/install/default.htm
   NOTE: Must download 3.0 Beta developer's pack. Do not use earlier 
versions.

3. Open Libnet-1.1.1/win32/Libnet.dsw (If you are using VC++6.0)
        Libnet-1.1.1/win32/Libnet-1.1.1-2002.sln (If youa are using Visual 
Studio .NET 20002)
        Libnet-1.1.1/win32/Libnet-1.1.1-2003.sln (If youa are using Visual 
Studio .NET 20003)

4. To properly setup the winpcap/libpcap dependencies.

   Visual Studio .NET Instructions.
   Select Tools/Options
      Under the options dialog, select Projects and then VC++ Directories
      Select Include files.
      Add the following path
      <path>wpdpack\Include
      Select Library paths.
      Add the following path
      <path>wpdpack\Lib

   Visual C++ 6.0 Instructions
   You will need to also install the Microsoft Platform SDK in order to have 
iphlpapi.h
   The platform SDK is available here: 
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/
   NOTE: The include order is important, or you will get redefinition 
errors. Put the platform sdk's directory first.

to do so select Tools/Options within Visual Studio 6.0

Select the Directories Tab
      Select Include files.
      Add the following path
	<path>Program Files\Microsoft SDK\include
	<path>wpdpack\Include
	<path>libnet\libnet-1.1.1\win32

      Select Library paths.
      Add the following path
	<path>Program Files\Microsoft SDK\Lib
        <path>wpdpack\Lib
	<path>libnet\libnet-1.1.1\win32\lib

5.Build the project opened. You will have a libnet.dll file in the debug 
folder.


6.copy the file "libnet.dll" to the directory, from which you run the .exe 
files which need libnet.(usually the debug folder of your project)
