SDL_winrt_main_NonXAML.cpp (2088B)

      1 /*
      2     SDL_winrt_main_NonXAML.cpp, placed in the public domain by David Ludwig  3/13/14

      8 /* At least one file in any SDL/WinRT app appears to require compilation
      9    with C++/CX, otherwise a Windows Metadata file won't get created, and
     10    an APPX0702 build error can appear shortly after linking.
     11 
     12    The following set of preprocessor code forces this file to be compiled
     13    as C++/CX, which appears to cause Visual C++ 2012's build tools to
     14    create this .winmd file, and will help allow builds of SDL/WinRT apps
     15    to proceed without error.
     16 
     17    If other files in an app's project enable C++/CX compilation, then it might
     18    be possible for SDL_winrt_main_NonXAML.cpp to be compiled without /ZW,
     19    for Visual C++'s build tools to create a winmd file, and for the app to
     20    build without APPX0702 errors.  In this case, if
     21    SDL_WINRT_METADATA_FILE_AVAILABLE is defined as a C/C++ macro, then
     22    the #error (to force C++/CX compilation) will be disabled.
     23 
     24    Please note that /ZW can be specified on a file-by-file basis.  To do this,
     25    right click on the file in Visual C++, click Properties, then change the
     26    setting through the dialog that comes up.
