c++ - 使用 GLFW3 编译，链接器错误 'undefined reference'

Question

有一个使用 GLFW3 的最小示例:

#include <GLFW/glfw3.h>

int main(int argc, const char * argv[]) {
    glfwInit();
}

...导致大量链接器错误:(小摘录)

Undefined symbols for architecture x86_64:
  "_CFArrayAppendValue", referenced from:
      _addJoystickElement in libglfw3.a(cocoa_joystick.m.o)
  "_CFArrayApplyFunction", referenced from:
      __glfwInitJoysticks in libglfw3.a(cocoa_joystick.m.o)
      _addJoystickElement in libglfw3.a(cocoa_joystick.m.o)
  "_CFArrayCreateMutable", referenced from:
      __glfwInitJoysticks in libglfw3.a(cocoa_joystick.m.o)

  ...

  "_objc_msgSend_fixup", referenced from:
  l_objc_msgSend_fixup_count in libglfw3.a(cocoa_monitor.m.o)
  l_objc_msgSend_fixup_objectAtIndex_ in libglfw3.a(cocoa_monitor.m.o)

  l_objc_msgSend_fixup_alloc in libglfw3.a(nsgl_context.m.o)
  l_objc_msgSend_fixup_release in libglfw3.a(nsgl_context.m.o)
  ...

OpenGL.framework 和 libglfw3.a 都是链接的。

这是什么原因？之前编译一个 glfw2 应用程序就像一个魅力。

If you are using the static library version of GLFW, add it and the Cocoa, OpenGL, IOKit and CoreVideo frameworks to the project as dependencies.
