The following set of preprocessor code forces this file to be compiled as C++/CX, which appears to cause Visual C++ 2012's build tools to create this .winmd file, and will help allow builds of SDL/WinRT apps to proceed without error. If other files in an app's project enable C++/CX compilation, then it might be possible for SDL_winrt_main_NonXAML.cpp to be compiled without /ZW, for Visual C++'s build tools to create a winmd file, and for the app to build without APPX0702 errors. In this case, if SDL_WINRT_METADATA_FILE_AVAILABLE is defined as a C/C++ macro, then the #error (to force C++/CX compilation) will be disabled. Please note that /ZW can be specified on a file-by-file basis. To do this, right click on the file in Visual C++, click Properties, then change the setting through the dialog that comes up. */ #ifndef SDL_WINRT_METADATA_FILE_AVAILABLE #ifndef __cplusplus_winrt #error SDL_winrt_main_NonXAML.cpp must be compiled with /ZW, otherwise build errors due to missing .winmd files can occur. #endif #endif /* Prevent MSVC++ from warning about threading models when defining our custom WinMain.
