// dump2def.cxx - Written and placed in public domain by Jeffrey Walton
// Create a module definitions file from a dumpbin file/
// Create a module definitions file from a dumpbin file.
// dump2def can be used to create a list of exports from
// a static library. Then, the exports can used to build
// a dynamic link library with the same exports.
//
// The workflow for Crypto++ is:
//
// 1. Open a Developer Prompt
// 2. CD to cryptopp/ directory
// 3. nmake /f cryptest.nmake cryptopp.dll
//
// The cryptopp.dll recipe first builds cryptlib.lib. Then it calls
// dumpbin.exe to export all symbols from cryptlib.lib and writes them
// to cryptopp.dump. The recipe then calls dump2def.exe to create a
// module definition file. Finally, the recipe builds cryptopp.dll
// using the module definition file cryptopp.def. The linker creates
// the import lib cryptopp.lib and export cryptopp.exp automatically.
//
// This is only "half the problem solved" for those who wish to use
// a DLL. The program must import the import lib cryptopp.lib. Then
// the program must ensure the library headers export the symbol or
// class with CRYPTOPP_DLL. CRYPTOPP_DLL is only present on some classes
// because the FIPS module only allowed approved algorithms like AES and
// SHA. Other classes like Base64Encoder and HexEncoder lack CRYPTOPP_DLL.
//
// CRYPTOPP_DLL simply adds declspec(dllimport) when CRYPTOPP_IMPORTS is
// defined. The limitation of requiring declspec(dllimport) is imposed by
// Microsoft. Microsoft does not allow a program to "import everything".
//
// If you would like to read more about the FIPS module and the pain it
// causes then see https://www.cryptopp.com/wiki/FIPS_DLL. In fact we
// recommend you delete the CryptDll and DllTest projects from the
// Visual Studio solution file.
