Setting Up your Project

In order to use the classes and functions in the Datasmith SDK, you'll need to tell your compiler and linker where to find the SDK's header files and compiled library, and you'll need to set up some pre-processor definitions.

Tip: If you create a new project in Visual Studio that uses the Datasmith SDK inside the same solution that contains the Unreal Engine source code (UE4.sln), the include directories and pre-processor definitions below are taken care of for you automatically by the Unreal Build Tool. However, most customers prefer to integrate the Datasmith SDK library into a standalone application outside of the Unreal Engine solution. In this case, you'll need to set these values yourself in your own Visual Studio or other IDE project.

1. Install Unreal Engine to a stable location on your computer.

   You can use the binary version that you install from the Epic Games Launcher, or you can download the source code from GitHub. Both have the header files you'll need. However, if you choose the source code distribution, you'll need to generate the UE4.sln file and build the Programs/Enterprise/DatasmithSDK project.

2. Add the following additional include directories for your project. You'll find all these folders within your Unreal Engine installation directory.

   DatasmithSDK\Public
   Engine\Source\Runtime\Core\Public
   Engine\Source\Runtime\CoreUObject\Public
   Engine\Source\Runtime\Projects\Public
   Engine\Source\Runtime\TraceLog\Public
   

3. Add the following pre-processor definitions for your project:

   UE_BUILD_DEVELOPMENT=1
   UE_BUILD_MINIMAL=1
   WITH_EDITOR=0
   WITH_EDITORONLY_DATA=1
   WITH_SERVER_CODE=1
   WITH_ENGINE=0
   WITH_UNREAL_DEVELOPER_TOOLS=0
   WITH_PLUGIN_SUPPORT=0
   IS_MONOLITHIC=1
   IS_PROGRAM=1
   PLATFORM_WINDOWS=1
   CORE_API=DLLIMPORT
   COREUOBJECT_API=DLLIMPORT
   DATASMITHEXPORTER_API=DLLIMPORT
   DATASMITHCORE_API=DLLIMPORT
   DIRECTLINK_API=DLLIMPORT
   WIN32=1
   _WIN32_WINNT=0x0601
   WINVER=0x0601
   UNICODE
   _UNICODE
   UE_BUILD_DEVELOPMENT_WITH_DEBUGGAME=0
   UBT_COMPILED_PLATFORM=Windows
   

4. Add the following additional library directories for your linker:

   Engine\Binaries\Win64\DatasmithSDK
   

5. Add the following additional library dependency for your linker:

   DatasmithSDK.lib
   

6. When you run your compiled application, it will need to load the Engine\Binaries\Win64\DatasmithSDK\DatasmithSDK.dll file. Either copy this file to the directory that contains your application’s executable file, or configure your application to load the .dll file from a different location.
