OpenCV error with android ndk vuforia

Question

I'm getting involved in ndk error of opencv of android program. I got the errors below when I added some opencv code to a vuforia sample of ImageTargets. And I think all these errors occur in .h files related to opencv(core.hpp, mat.jpp, etc...)

(I have too much errors, so I could not list all of them)

All I added to ImageTargets.cpp are includes of opencv. Errors do not occur when I exclude include codes below. I use opencv sdk 2.4.6 for android.

#include "opencv2/core/core.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <opencv2/highgui/highgui.hpp>

Do someone know what causes these errors?

Answer 1

You should change the APP_STL setting in Application.mk to be gnustl_static. You should also change the cmake builder to the Android Builder.

Answer 2

You should add some c++ head files .You can try to add the following files in the error reported files,such as "memory" ,"limits".

#include <memory>
#include <limits>

What difference does it make when I include <limits> or <limits.h> in my c++ code
