Hello,

I tried to compile the latest SDL 2.0 snapshot with MinGW on Windowns 8.
However, I'm having some problems with this.
When I first built SDL 2.0, I got an error saying that it wasn't built with force feedback support when running my program with it.
So I thought that I probably needed some DirectX headers for it to work correctly (and of course to get the better dsound backend).
Thus I copied the DirectX development headers and libraries from http://www.libsdl.org/extras/win32/mingw32/README.txt .
But then I got an error message saying that the file "wbemcli.h" was missing. I copied this header and "xinput.h" from the mingw-w64 project, but the headers don't seem to be compatible as I get a lot of error messages like this one:
c:\mingw\bin\../lib/gcc/mingw32/4.7.2/../../../../include/wbemcli.h:499:80: error: unknown type name 'VARIANT'

Do you know how I could solve these problems or do I have to use the MinGW version from mingw-w64 instead?
Thank you for your answers in advance!

I tried to compile SDL with mingw-w64 now. Compiling has worked (I still need to test it with my program) but it seems that everything is the way it should be.

However, I had to apply a small change to the SDL source code: I had to remove the following lines from src/joystick/windows/SDL_dxjoystick.c:

DEFINE_GUID(IID_IWbemLocator, 0xdc12a687,0x737f,0x11cf,0x88,0x4d,0x00,0xaa,0x00,0x4b,0x2e,0x24);

because IID_IWbemLocator is already defined in the header file wbemcli.h.
Probably this should somehow be fixed in the source code.

To compile using normal MinGW (I'm only just now experimenting with MinGW-W64 right now), you only need a few files, which can be ripped from wine and patched slightly to work (in fact, this is basically what MinGW-W64 did).

Perhaps the Visual C++ headers include oaidl.h while the MinGW-W64 ones do not, causing SDL to have this error.

oaidl.h defines the VARIANT type. Including this before the offending header should do the trick.

I managed to compile SDL, SDL_image, ... with mingw-w64 and the libraries work as expected.

But I'm a bit curious about using the header files from wine for mingw: What exactly has to be done to make them work?
