The colliding definitions are:

#ifdef __cplusplus
#define __FIReference_1_BYTE ABI::Windows::Foundation::IReference<BYTE >
#endif /* __cplusplus */

and

#ifdef __cplusplus
#define __FIReference_1_boolean ABI::Windows::Foundation::IReference<boolean >
#endif /* __cplusplus */

because boolean and BYTE are both typedefed to unsigned char.

This breakage was introduced by the change in windows.foundation.idl in mingw-w64/mingw-w64@77eaa95 which added interface Windows.Foundation.IReference<boolean>

Biswa96 · 2024-10-12T05:38:03Z

I have asked about this issue in the relevant upstream merge request https://gitlab.winehq.org/wine/wine/-/merge_requests/6594

zzhiyi · 2024-10-12T06:44:09Z

I don't think this is a bug in Wine. Native headers have both Windows.Foundation.IReference<BYTE> and Windows.Foundation.IReference<boolean> and no conflicts.

alvinhochun · 2024-10-12T08:06:01Z

windows.foundation.h in wInsdk does not have the string IReference at all from what I can see.

Biswa96 · 2024-10-12T12:45:16Z

It's in windows.foundation.idl

raedrizqie · 2024-10-12T14:57:00Z

it seems slightly different here, no?

struct __declspec(uuid("3c00fd60-2950-5939-a21a-2d12c5a01b8a"))
IReference<bool> : IReference_impl<ABI::Windows::Foundation::Internal::AggregateType<bool, boolean>> {
static const wchar_t* z_get_rc_name_impl() {
return L"Windows.Foundation.IReference`1<Boolean>"; }
};
typedef IReference<bool> __FIReference_1_boolean_t;
#define ____FIReference_1_boolean_FWD_DEFINED__
#define __FIReference_1_boolean ABI::Windows::Foundation::__FIReference_1_boolean_t

https://github.com/tpn/winsdk-10/blob/9b69fd26ac0c7d0b83d378dba01080e93349c2ed/Include/10.0.14393.0/winrt/windows.foundation.h#L8895-L8902

alvinhochun · 2024-10-12T16:09:35Z

In both the latest winsdk 10.0.22621.0 and the 4-year-old winsdk 10.0.19041.0, windows.foundation.h does not contain IReference. 10.0.14393.0 is ancient at this point.

Frankly I don't quite understand how the different instantiations of IReference are being handled in the winsdk. It seems in the winsdk they are spread across different headers, practically being defined "on demand" only if a header file requires a specific instantiation (an example being windows.ui.xaml.controls.primitives.h).

However it is possible that we can ignore this difference here. Practically speaking, it doesn't matter as long as the generated definitions are actually correct...

...But it looks like the definition of IReference<boolean> is wrong. Instead of becoming

struct IReference<boolean > : IReference_impl<boolean >

it should become

struct IReference<bool> : IReference_impl<ABI::Windows::Foundation::Internal::AggregateType<bool, boolean>>

WinRT has a native boolean type which, according to https://learn.microsoft.com/en-us/windows/win32/winrt/base-data-types is supposed to be mapped to bool in C++. In fact, anything that uses boolean in the IDL probably needs special handling in WIDL.

I would argue interface Windows.Foundation.IReference<boolean> should be removed from the IDL until WIDL can handle it properly.

lhmouse · 2024-10-14T11:41:19Z

[19:37:14] <lh_ideapad> WIDL generates GUID e5198cc8-2873-55f5-b0a1-84ff9e4aad62 for IReference<BYTE>, which matches IReference<byte> in windows.device.usb.h from Windows SDK.
[19:38:17] <lh_ideapad> WIDL also generates GUID 3c00fd60-2950-5939-a21a-2d12c5a01b8a for IReference<boolean>, which matches IReference<bool> in windows.media.import.h from Windows SDK.
[19:39:34] <lh_ideapad> the second one is incorrect. the GUID 3c00fd60-2950-5939-a21a-2d12c5a01b8a belongs to IReference<Boolean>.
[19:40:17] <lh_ideapad> IReference<boolean> shall be the same as IReference<BYTE>; it's a redeclaration and no class should be generated.

Avoids duplicate definition as described in msys2/MINGW-packages#22160

Congrats! This issue breaks both Firefox and Chromium.

I think that you can try patching WIDL. The quick, dirty and improper fix would be to tamper with the tokenizer so it treats boolean as BYTE.

nodejs is also affected by this bug

Biswa96 · 2024-10-27T13:55:40Z

Would it be a proper workaround to remove the IReference<boolean> in the IDL file? I can create a PR to remove that.
