The MIDL compiler, RPC header files, and RPC import libraries that are necessary to build interface marshalers might not be a part of your development environment. They are really part of Microsoft's RPC development kit. They can be found in the Win32 SDK but are not included with compilers such as Visual C++. Specifically, you need the following files from the Win32 SDK in order to work with MIDL:
MIDL.EXE | The MIDL compiler |
RPCPROXY.H | The header file for interface marshalers |
UNKWN.IDL | Contains the IDL description for IUnknown that you include in your own IDL files; pulls in WTYPES.IDL |
WTYPES.IDL | Contains IDL descriptions of Windows types, structures, and so on |
RPCRT4.LIB | A mixed static-link and import library that provides the rest of the interface proxy/stub implementation you'll need |
In addition, the Win32 SDK contains full documentation for MIDL and the IDL language. This book doesn't document them beyond what is in the following section.
