Quoted Jeremy Huddleston <email@hidden>:
You don't put it anywhere. That code already exists, and is where the
error is coming from.
The only thing I can really conclude from your output is that on your system
CGDisplaySamplesPerPixel(kCGDirectMainDisplay) *
DisplayBitsPerSample(kCGDirectMainDisplay)
is not 8, 15, or 24 for some reason (unfortunately the error message
isn't helpful in narrowing that down, so I'll update it).
What is the depth of your display?
Just a guess, but should we handle 16-bit display depths in XQuartz?
Does Aqua support that in addition to 15?
16-bit displays generally have 6 bits for green, and 5 bits for red
and blue. The color green is more visually significant to the human
eye, so an extra bit is allocated.

If it is to compile X11, I do not have Xcode installed (and I am not
downloading)

This is really weird... What is the depth of your display? It should be
detected by:
if(depth == -1) {
depth = CGDisplaySamplesPerPixel(kCGDirectMainDisplay) *
CGDisplayBitsPerSample(kCGDirectMainDisplay);
//dfb->depth = CGDisplaySamplesPerPixel(kCGDirectMainDisplay) *
CGDisplayBitsPerSample(kCGDirectMainDisplay);
//dfb->bitsPerRGB = CGDisplayBitsPerSample(kCGDirectMainDisplay);
//dfb->bitsPerPixel = CGDisplayBitsPerPixel(kCGDirectMainDisplay);
}
switch(depth) {
case -8: // broken
FatalError("Unsupported color depth %d\n", darwinDesiredDepth);
dfb->visuals = (1 << StaticGray) | (1 << GrayScale);
dfb->preferredCVC = GrayScale;
dfb->depth = 8;
dfb->bitsPerRGB = 8;
dfb->bitsPerPixel = 8;
dfb->redMask = 0;
dfb->greenMask = 0;
dfb->blueMask = 0;
break;
case 8: // broken
dfb->visuals = PseudoColorMask;
dfb->preferredCVC = PseudoColor;
dfb->depth = 8;
dfb->bitsPerRGB = 8;
dfb->bitsPerPixel = 8;
dfb->redMask = 0;
dfb->greenMask = 0;
dfb->blueMask = 0;
break;
case 15:
dfb->visuals = LARGE_VISUALS;
dfb->preferredCVC = TrueColor;
dfb->depth = 15;
dfb->bitsPerRGB = 5;
dfb->bitsPerPixel = 16;
dfb->redMask = 0x7c00;
dfb->greenMask = 0x03e0;
dfb->blueMask = 0x001f;
break;
case 24:
dfb->visuals = LARGE_VISUALS;
dfb->preferredCVC = TrueColor;
dfb->depth = 24;
dfb->bitsPerRGB = 8;
dfb->bitsPerPixel = 32;
dfb->redMask = 0x00ff0000;
dfb->greenMask = 0x0000ff00;
dfb->blueMask = 0x000000ff;
break;
default:
