The following items are not strictly necessary to do a build, but are highly recommended:
A workspace is available under build/VC6/ to assist in compiling on Visual C++.
A workspace is available under build/VC.NET_2003/ to compile on VC.NET 2003.
Several environment variables need to be set for the VC .NET 2003 build. There is a sample batch file to set these variables and start the IDE here: http://linux.dell.com/libsmbios/download/windows/dev_environment. Also included are pre-compiled versions (with source) of xerces and cppunit, so everything that you need to compile all of the tools is there.
