Hi,
I'm trying to recompile Qt from Msys2, and I get the following error:

This Change was Introduced in 6c8c2a. And I don't really see the need for the
access through a pointer. I have changed it to:
static inline float DXVA2FixedToFloat(DXVA2_Fixed32 f32) {
return (float)f32.Value + (float)f32.Fraction / (1 << 16);
}
static inline DXVA2_Fixed32 DXVA2FloatToFixed(float f) {
DXVA2_Fixed32 f32;
f32.Value = ((ULONG) (f * (1 << 16))) >> 16;
f32.Fraction = ((ULONG) (f * (1 << 16))) & 0xFFFF;
return f32;
}
And at least Qt seems to compile (still ongoing).
And yes I know it's a generated file, but I just want to progress here.
Kind regards,
Björn.
