Unkown错误编译opencv框架 [英] Unkown error compiling opencv framework

问题描述

Xcode给了我下面的错误，我真的不知道该怎么做，让我疯狂。
我正在导入一个OpenCV框架，所以也许问题出在那里或者与编译器有关。
任何人都可以告诉我该怎么做或搜索？
Thanks。

 未定义符号：_CGImageDestinationCreateWithURL，引用自：
 cv :: ImageIOEncoder ::在OpenCV（grfmt_imageio.o）_CGImageDestinationAddImage中写入（cv :: Mat const&，std :: vector< int，std :: allocator< int>> const&），引用自：
 cv :: ImageIOEncoder :: OpenCV（grfmt_imageio.o）_CGImageSourceCreateImageAtIndex中的write（cv :: Mat const&，std :: vector< int，std :: allocator< int>> const&），引用自：
 cv： ：OpenCV中的ImageIODecoder :: readHeader（）（grfmt_imageio.o）_CGImageDestinationFinalize，引用自：
 cv :: ImageIOEncoder :: write（cv :: Mat const&; std :: vector< int，std :: （grfmt_imageio.o）_CGImageSourceCreateWithURL，引用自：
 cv :: ImageIODecoder :: readHeader（）在OpenCV中（grfmt_imageio.o）ld：符号（s）不是在OpenCV（grfmt_imageio.o）中的分配器< int>>找到collect2：ld返回1退出状态
  

为了未来的访客（就像我;-)），我报告了古斯塔沃的自我回答： $ b $ b

添加
ImageIO.framework
至
链接框架和库

Xcode is giving me the following error, I don't really know what to do, is driving my crazy. I'm importing an OpenCV framework so maybe the problem is there or something related to the compiler. Could anyone tell me what to do or search for? Thanks.

      Undefined symbols:   "_CGImageDestinationCreateWithURL", referenced from:
      cv::ImageIOEncoder::write(cv::Mat const&, std::vector<int, std::allocator<int> > const&)in OpenCV(grfmt_imageio.o)   "_CGImageDestinationAddImage", referenced from:

解决方案

Just for sake of future visitors (like me ;-)), I report the Gustavo self-answer:

Add "ImageIO.framework" to "Linked Frameworks and Library"
