錯(cuò)誤提示如下：

Undefined symbols for architecture x86_64:"cv::_InputArray::_InputArray(cv::Mat const&)", referenced from:_main in test-41a30e.o"cv::namedWindow(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, int)", referenced from:_main in test-41a30e.o"cv::destroyWindow(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:_main in test-41a30e.o"cv::Mat::deallocate()", referenced from:cv::Mat::release() in test-41a30e.o"cv::imread(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, int)", referenced from:_main in test-41a30e.o"cv::imshow(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, cv::_InputArray const&)", referenced from:_main in test-41a30e.o"cv::waitKey(int)", referenced from:_main in test-41a30e.o"cv::fastFree(void*)", referenced from:cv::Mat::~Mat() in test-41a30e.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

解決方法:

brew install pkg-config brew reinstall opencv # 加入如下參數(shù)編譯 g++ $(pkg-config --cflags --libs opencv) test.cpp -o Test # 運(yùn)行程序 ./Test
