as C++/CX, which appears to cause Visual C++ 2012's build tools to

to proceed without error.

be possible for the .cpp file including SDL_main.h 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.
