体系结构i386的未定义符号:用于OpenCV项目

问题描述

我正在尝试构建此项目，但其显示在错误下方，

I am trying to build this project, but its display below error,

Undefined symbols for architecture i386:
  "cv::merge(std::vector<cv::Mat, std::allocator<cv::Mat> > const&, cv::_OutputArray const&)", referenced from:
      -[RRMainViewController colorSobelEdge:isVertical:] in RRMainViewController.o
  "cv::split(cv::Mat const&, std::vector<cv::Mat, std::allocator<cv::Mat> >&)", referenced from:
      -[RRMainViewController colorSobelEdge:isVertical:] in RRMainViewController.o
  "cv::Exception::Exception(int, std::string const&, std::string const&, std::string const&, int)", referenced from:
      -[RRMainViewController floodFillPostprocess:WithColor:] in RRMainViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已添加OpenCV.framework并将此行添加到.pch文件中

I have added OpenCV.framework and added this line in .pch file

#ifdef __cplusplus
#import <opencv2/opencv.hpp>
#endif

将此库添加到项目中

但是仍然出现错误..请帮助...提前谢谢..

But still got above error.. please help... thanx in advance..

推荐答案

Opencv框架或某些其他文件未在构建阶段添加.转到项目设置->构建阶段->与库链接二进制文件，然后检查列表中是否存在opencv.否则，请点击+并将其添加然后进入构建阶段以编译源代码，并确保RRMainViewController.m存在于列表中.否则，请点击+并将其添加

Opencv framework or some other files are not added in the build phases. Go to project settings->Build phases->Link binary with libraries and check if opencv exists in the list. Otherwise click on + and add itThen go in the build phases to compile sources and make sure RRMainViewController.m is present in the list. Otherwise click on + and add it
