3.Qt 編寫的代碼運行時出現類似錯誤：

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

這種一般是鏈接庫沒有添加：
往項目的pro文件中的動態庫鏈接部分添加報錯的庫：
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 <------ 這個庫沒有添加導致的，往這里添加
