Compiling the Packet Driver

The Packet Driver is platform dependent, therefore it MUST be compiled on the platform where you intend to use it.

• Compiling on Windows NT 4.0
• Compiling on Windows 95/98

Compiling on Windows NT 4.0

Software requirements:

• Microsoft Windows NT 4.0 operating system
• Microsoft Driver Developer Kit (DDK) for NT 4.0
• Microsoft Software Development Kit (SDK)
• Microsoft Visual C++ 6.0

If your system satisfies the requirements, follow these steps:

1. From the Window NT Start menu, select the folder Programs and then Windows NT DDK. From here select the voice Checked Build Environment if you want to build a debug version, or Free Build Environment if you want to build a release version.
2. A DOS shell will be opened. Move to the directory whit the driver's source code and type the command
   
   compile
   
   This command will generate the driver (packet.sys). The debug version of the files will be generated in the directory \i386\checked. The release version in \i386\free.
3. To compile the sources of packet.dll, load the project contained in the directory packetNT\dll\project in the Visual C++ 6.0 IDE. Build the project to obtain the packet.dll and packet.lib files. The debug version of these files will be generated in the directory packetNT\dll\project\debug, the release version in packetNT\dll\project\release.

Windows 95/98 platform

To compile the driver there are the following software requirements:

• Windows 95/98 operating system
• Driver Developer Kit (DDK) for Windows 95
• Software Development Kit (SDK)
• Visual C++ 6.0

If your system satisfies the requirements, follow these steps:

1. Open a dos shell
2. Go in the VisualC++ BIN directory (for example C:\DEVSTUDIO\VC\BIN) and execute the command
   
   Vcvars32
   
3. Go in the SDK directory (for example C:\MSSDK) and execute the command
   
   Setenv sdk_path
   
   where sdk_path is the directory of SDK (for example Setenv C:\MSSDK)
4. Go in the DDK directory (for example C:\DDK) and execute the command
   
   Ddkenv 32 net
   
5. Move to the directory whit the driver's source code and type the command
   
   nmake rtl
   
   to obtain a release version, or
   
   nmake
   
   to obtain a debug version.
   The release version of packet.vxd will be placed in the retail directory, the debug version in the debug directory.

Warning: we often encountered problems compiling the driver for Windows 95. In particular on some systems the NMAKE utility was not able to launch ADRC2VXD (the driver is generated without the copyright informations), and on other systems the debug version was not compiled correctly. We don't know the cause of these problems.
