错误：未定义的引用符号到cv :: VideoCapture :: ~VideoCapture（），命令行中缺少DSO

Question

我正在尝试在raspberry pi上运行我的opencv代码，但是我收到以下错误

/usr/bin/ld: CMakeFiles/main.dir/main.o: undefined reference to symbol 'cv::VideoCapture::~VideoCapture()'
/usr/local/lib/libopencv_videoio.so.3.0: error adding symbols: DSO missing from command line

Answer 1

DSO代表＆＃34;动态共享对象＆＃34;所以它可能是一个链接错误。请参阅：openCV 2.4.7 error adding symbols: DSO missing from command line

将-lopencv_features2d添加到编译路径。
