关于以下内容的定义有什么想法吗？
ahcarpenter@ahcarpenter-laptop:~$ g++ objectmarker.o -o objectmarker
objectmarker.o: In function `on_mouse(int, int, int, int, void*)':
objectmarker.cpp:(.text+0x12f): undefined reference to `cvCloneImage'

我尝试过这个，它对我有用：
sudo g++ -I/usr/include/opencv main.cpp -o main -lopencv_core -lopencv_imgproc
-lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d
-lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann -I /lib/
-I /home/ubuntu/micros/opencv_directory/include/opencv
