iphone - opencv框架与opengles trows错误？

Question

我尝试从 this link 运行一个基本的 opengl 程序。我可以成功运行它。现在我需要在其中添加opencv的一些功能。 所以我从this link添加了opencv框架。

添加框架后，我将文件更改为.mm，并且编译良好。当我添加“cv::Mat Variable”时，问题就出现了。我收到以下错误。造成这种情况的原因是什么？

以下是当我添加“cv::Mat Variable”时出现的错误。

  Undefined symbols for architecture i386:
  "_gzclose", referenced from:
      _cvReleaseFileStorage in OpenCV(persistence.o)
      _cvOpenFileStorage in OpenCV(persistence.o)
  "_gzeof", referenced from:
      icvEof(CvFileStorage*)      in OpenCV(persistence.o)
  "_gzgets", referenced from:

这解决了我的问题。添加opencv库文件

AVFoundation.framework
ImageIO.framework
libz.dylib

应添加

。这个链接清楚地解释了这一点。 http://aptogo.co.uk/2011/09/opencv-framework-for-ios/
