Mac OSX Sierra CoreFoundation/CoreServices/CoreGraphics not working

When I try to compile anything which includes CoreFoundation, CoreServices or CoreGraphics, e.g Carbon, I get the following error message.

gcc x.c -framework Carbon

Does anyone have an idea what the problem might be? I am not sure if this started after updating to macOS Sierra or Xcode to version 8.1. Edit: The program seems to compile in Xcode, but not in terminal with homebrew gcc 6.2.

/System/Library/Frameworks/CoreFoundation.framework/Headers/CFDateFormatter.h:53:34: error: 'introduced' undeclared here (not in a function) kCFISO8601DateFormatWithYear API_AVAILABLE(macosx(10.12), ios(10.0), watchos(3.0), tvos(10.0)) = (1UL << 0),

IMHO it's just that this header is not supported by gcc-6.2 but only by clang. Maybe it will be "fixed" with gcc-7.

A similar problem exists with gcc-5.x and El Capitan (sdk 10.11) where gcc-6.x is needed in order to build with the Apple headers like this one.

As stated here, Carbon has long been deprecated. However, you might try AppKit:

gcc x.c -framework AppKit

For me it works fine when I write pure-C apps for OS X.

[EDIT:] Now the code.

#include <ApplicationServices/ApplicationServices.h>
#include <unistd.h>

int main() {
    while (!CGEventSourceKeyState(kCGEventSourceStateHIDSystemState, 0x7E))
        usleep(10000);
    return 0;
}

This app only depends on AppKit and loops until up arrow (scan code 0x7E) is pressed.

Here`s the full list of codes (not sure where they are in official headers): Carbon's Virtual Key Codes.

You tagged this with "Core-Foundation" but the availability macros you're talking about (described more in detail in the first couple paragraphs of the Foundation Release Notes for macOS 10.12 & iOS 10 describe the API Availability Macros a bit more in detail.

I suspect you might need to simply include the Foundation framework in your build (to pick up these macros which CoreFoundation & CoreGraphics appear to depend on) and you should be okay going forward.
