我有 Mac OS Lion 10.7.5 和 xCode 4.6。我已经下载了一个opencv 模板。然后检索一个框架并想创建我自己的项目。首先我安装 cmake 2.8.10，添加一个框架，就是这样。在 main.mi 中尝试创建一个窗口：

   #import <UIKit/UIKit.h>
   #include "opencv2/highgui/highgui_c.h"
   #import "AppDelegate.h"

int main(int argc, char *argv[])
{
    IplImage* img = cvLoadImage("1.png", 8);
   cvNamedWindow("Example",CV_WINDOW_AUTOSIZE); //Thread 1: signal SIGANRT

    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

在调试区域中，我得到了以下信息：

OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /Volumes/minijHome/Documents/xcode_mini/hillegass/advancedIOS/postCourse/openCV/clean-downloads/openCVgitClone/opencv/modules/highgui/src/window.cpp, line 652
libc++abi.dylib: terminate called throwing an exception

我必须做什么？
