Running OpenCV 3 in Mac Terminal

Question

For the past week, I have been trying to run some simple OpenCV programs using the terminal. I have tried many tutorials and recommendations from various forums with little

I create a similar file that maybe can help you.

First I use:

sudo brew install opencv

Then I install the opencv.3.0 according to the hint given by the terminal. Then in the .cpp file which needs the API from opencv, I use:

#include "opencv2/opencv.hpp"

As my only include file about opencv. Actually, at that project I use highgui, core, and imgprog. But no worries here, I will show you how to solve them in linking part.

After you finish your project, you are going to compile your project on the terminal.

Because I also used the JNI interface, so I still need to link the jni.h.

Here we go:

g++   xxxx.cpp xxx.cpp -lstdc++ -fPIC -shared (to create a shared object)  
-I/absolute path/ (we can use -I  to be followed with  the absolute path of the library you need to use )
-I/Users/yuanzhan/Downloads/OpenCV-2.0.0/src/
-I /Users/yuanzhan/Downloads/OpenCV-2.0.0/include/opencv/ -I/usr/local/Cellar/opencv3/3.1.0_3/lib   -lopencv_core (open the library for use if you use the API fro here)-lopencv_highgui -lopencv_imgproc -L.(i put the cv2. on local otherwise you can add the absolute path here) -lcv2(use the package)  -v -o libopenCvSDK.so(generate my .so package).
