How do I support c++11 in Opencv 3 Android NDK -

can me, please?

i doing next changes support c++11 opencv 3 in android ndk:

i change app_stl := gnustl_static app_stl := c++_static

application.mk

app_stl := c++_static app_cppflags := -std=c++11 -frtti -fexceptions app_abi :=  armeabi armeabi-v7a mips x86 arm64-v8a x86_64 mips64 app_platform := android-14 # use select gcc instead of clang ndk_toolchain_version := 4.9 

android.mk

local_path := $(call my-dir) local_path_lib_dir:=library/lib/classifier    include $(clear_vars)   opencv_camera_modules:=off opencv_install_modules:=on  opencv_lib_type:=shared include ../../../opencv-android-sdk/sdk/native/jni/opencv.mk  local_module:= detection_based_tracker  local_src_files := detectionbasedtracker_jni.cpp \                               library/jniutils.cpp \                              ${ local_path_lib_dir}/logic.cpp \                              ${ local_path_lib_dir}/logic2.cpp \  local_c_includes += $(local_path)  local_ldlibs     += -llog -ldl -lm -latomic -l$(local_path)/libs/armeabi                             - l$(local_path)/libs/armeabi-v7a  -l$(local_path)/libs/mips                             -l$(local_path)/libs/x86  -l$(local_path)/libs/arm64-v8a                             -l$(local_path)/libs/mips64                            -l$(local_path)/libs/x86_64  local_cppflags += -ljnigraphics -d_linux  -dboost_has_pthreads -fexceptions -std=c++11                                   -i$(local_path)/  -i$(local_path)/library/lib/pico/ local_cpp_features :=  exceptions rtti app_optim := debug include $(build_shared_library) 

when compile android app android ndk r10e. have next errores in log:
