android - NDK - include error -


i need because drives me crazy. cause error?

the error is

"jni/algorithm.cpp:4:33: fatal error: opencv2/core/core.hpp: no such file or directory  #include <opencv2/core/core.hpp>                                  ^ compilation terminated. make: *** [obj/local/arm64-v8a/objs/algorithm/algorithm.o] error 1"

my algorithm.cpp is:

#include <jni.h> #include <string.h> #include <opencv2/core/core.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/features2d/features2d.hpp> #include "opencv2/highgui/highgui.hpp" #include "opencv2/imgproc/imgproc_c.h"  using namespace std; using namespace cv;  extern "c" {     jniexport jlong jnicall java_com_example_hematoma_mainactivity_fce(jnienv *env, jobject obj, jlong matimage)           {               mat *jni_image  = (mat*) matimage;                return (jlong)jni_image;            } }

my android.mk is:

local_path := $(call my-dir)  include /home/nemesis/adt-bundle-linux-x86_64-20140702/opencv-2.4.10-android-sdk/sdk/native/jni/opencv.mk  include $(clear_vars) local_module := algorithm local_src_files := algorithm.cpp  local_c_include := /home/nemesis/adt-bundle-linux-x86_64-20140702/opencv-2.4.10-android-sdk/sdk/native/jni/include/opencv2/core/core.hpp local_c_include += /home/nemesis/adt-bundle-linux-x86_64-20140702/opencv-2.4.10-android-sdk/sdk/native/jni/include/ include $(build_shared_library)

the error occurs when ndk try build .so

thanks in advance.

local_c_include := /home/nemesis/adt-bundle-linux-x86_64-20140702/opencv-2.4.10-android-sdk/sdk/native/jni/include/opencv2

should be

local_c_includes := /home/nemesis/adt-bundle-linux-x86_64-20140702/opencv-2.4.10-android-sdk/sdk/native/jni/include

ie, plural , should point location following relative path: 

#include <opencv2/core/core.hpp>
