3.Qt 编写的代码运行时出现类似错误:

/usr/local/lib/libopencv_imgcodecs.so.3.1:-1: error: error adding symbols: DSO missing from command line

这种一般是链接库没有添加:
往项目的pro文件中的动态库链接部分添加报错的库:
如下所示:

INCLUDEPATH += /usr/local/include \
/usr/local/include/opencv \
/usr/local/include/opencv2 LIBS += /usr/local/lib/libopencv_highgui.so \
/usr/local/lib/libopencv_core.so \
/usr/local/lib/libopencv_imgproc.so \
/usr/local/lib/libopencv_imgcodecs.so <------ 这个库没有添加导致的,往这里添加
