Mac OSX Sierra CoreFoundation/CoreServices/CoreGraphics不起作用

当我尝试编译任何包含CoreFoundation，CoreServices或CoreGraphics（例如Carbon）的东西时，出现以下错误消息。Mac OSX Sierra CoreFoundation/CoreServices/CoreGraphics不起作用

有没有人有一个想法是什么问题可能是什么？我不确定这是否在更新到macOS Sierra或Xcode版本8.1后开始。编辑：该程序似乎编译在Xcode，但不是在终端与自制gcc 6.2。

您与“核心基金”，但你在谈论（具体的Foundation Release Notes for macOS 10.12 & iOS 10的第一几段描述更多的描述API可用性宏有点更详细的可用性宏标记此。

我怀疑你可能需要简单地包括在构建基础架构（拿起这些宏其中的CoreFoundation & CoreGraphics中似乎依赖），你应该没问题前进。

好吧，我会试试！ –

我试图在我的c文件中包含，它带来了很多错误。我也尝试使用-framework Foundation进行编译，但似乎没有帮助。难道我做错了什么？ –

@ Robert.S是的。你现在做错的主要事情是试图用ObjC-only包含来编译C语言。 – hidefromkgb

如前所述here，碳早已被弃用。但是，你可以尝试AppKit：

gcc x.c -framework AppKit

对我来说，当我写纯-C的应用程序为OS X

它工作正常[编辑：现在的代码。

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

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

此应用只取决于了AppKit和循环，直到向上箭头（扫描码0x7E）被按下。

这里是代码的完整列表（不能确定它们在官方标题中）：Carbon's Virtual Key Codes。

AppKit是否允许您读取当前的全局键盘状态，例如，如果某个键是KeyDown，而不创建某种窗口？我创建终端应用程序，这是我使用它的唯一功能。 –

@ Robert.S：添加了代码。 – hidefromkgb

你是最棒的，谢谢！ –

恕我直言，这只是这头不是由GCC-6.2，但只有铛支持。也许它会被gcc-7“固定”。

gcc-5.x和El Capitan（sdk 10.11）存在一个类似的问题，其中需要使用gcc-6.x来构建像这样的Apple标头。
