The _RWCONFIG=<buildtype> command line macro defines for you all the preprocessor macros required by a particular build type of SourcePro. The prebuilt SourcePro libraries in SourcePro for Open Sources Databases are all shared libraries, also called dynamically linked libraries (DLLs) on Windows.

On Windows, the shared libraries are built with multithreading support and using the Microsoft Visual C++ or Microsoft Visual Studio .NET implementation of the C++ Standard Library. For this build type, set the command line macro as ‑D_RWCONFIG=12d for a release build, or ‑D_RWCONFIG=15d for a debug build.

On UNIX, the shared libraries are built with multithreading support and using the compiler’s implementation of the C++ Standard Library. Set the following command line macro for this build type ‑D_RWCONFIG=12d for a release build, and ‑D_RWCONFIG=15d for a debug build.
