opencv - 无法在XCode中链接OpenCV框架符号

在我的项目中，我正在使用一个正在运行的演示中的OpenCV框架，其中缺少一些小问题。

重现步骤:

从http://aptogo.co.uk/2011/09/opencv-framework-for-ios/下载示例应用程序

用钛创建一个新的Titainum iOS模块create --platform = iphone --type = module --dir =。 --name = opencv --id = opencv

打开XCode项目，从FaceTracker应用程序和其他必需的框架中拖入OpenCV框架。

将OTHER_LDFLAGS = $(继承)-framework OpenCV添加到module.xcconfig

创建名为OpencvView和OpencvViewProxy的新TiUIView和TiUIViewProxy类。

在新的OpencvView类中，实例化使用OpenCV的UIViewController。

该构建将构建Titanium模块，但是当我尝试运行模块测试工具时，我收到有关OpenCV对象的以下错误:

最佳答案

我在Xcode 4.5.1上使用默认的Apple llvm编译器时遇到了类似的问题。尝试将其更改为gcc(通过构建选项)，然后查看是否可行。
