带有opengles的opencv框架引发错误？

Question

我尝试从此链接运行基本的opengl程序。 我可以成功运行它。 现在，我需要在其中添加一些opencv功能。 因此，我从此链接添加了opencv框架。

添加框架后，我将文件更改为.mm及其编译良好。 当我添加“ cv :: Mat Variable”时，问题就来了。 我收到以下错误。 这是什么原因呢？

以下是我添加“ cv :: Mat变量”时遇到的错误。

  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:
      icvGets(CvFileStorage*, char*, int)in OpenCV(persistence.o)
  "_gzopen", referenced from:
      _cvOpenFileStorage in OpenCV(persistence.o)
  "_gzputs", referenced from:
      icvPuts(CvFileStorage*, char const*)in OpenCV(persistence.o)
  "_gzrewind", referenced from:
      _cvOpenFileStorage in OpenCV(persistence.o)
ld: symbol(s) not found for architecture i386

这解决了我的问题。 添加添加opencv库文件

AVFoundation.framework
ImageIO.framework
libz.dylib

应该添加。 并且此链接对此进行了清晰的解释。 http://aptogo.co.uk/2011/09/opencv-framework-for-ios/
