错误:对cv:: videoccapture::~ videoccapture()的引用符号未定义，命令行中缺少DSO

Question

我试图在树莓派上运行我的opencv代码，但我得到以下错误

/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"动态共享对象"，所以这可能是一个链接错误。openCV 2.4.7错误添加符号:命令行缺少DSO

将-lopencv_features2d添加到编译路径
