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

Can you help me, please?
I am doing the next changes to support c++11 with opencv 3 in android NDK:
I change from APP_STL := gnustl_static to APP_STL := c++_static
Application.mk
APP_STL := c++_static

APP_ABI := armeabi armeabi-v7a mips x86 arm64-v8a x86_64 mips64

How to build TensorFlow Lite and use in Qt project?

I am trying to start project:
https://mechatronicsblog.com/tensorflow-lite-integration-with-qt-and-v-play-for-multi-platform-machine-learning-apps-on-ios-and-android/
But there is an issue - Tensorflow submodule is incorrect.
I downloaded Tensorflow library from main repo by the following command:
git clone https://github.com/tensorflow/tensorflow.git
Then I updated dependencies:
tensorflow/lite/tools/make/download_dependencies.sh
Then I built the library by the following command:
bazel build --cxxopt='-D_GLIBCXX_USE_CXX11_ABI=0' -c opt --config=android_arm tensorflow/lite/java:libtensorflowlite_jni
Here's what WORKSPACE looks like:
android_sdk_repository(
name = "androidsdk",
api_level = 21,
build_tools_version = "26.0.2",
path = "/home/user/Android/SDK",
)
android_ndk_repository(
name = "androidndk",
api_level = 20,
path = "/home/user/android-ndk-r20b",
)
The result was successful.
Then I copied the library folder and pasted it in the root of the project folder.
I did not change .pro file

Compiler Clang Qt 5.13.2 for Android ARMv7

The result was failed.

I would like to know how to build up and include Tensorflow library for Qt project.

make: *** [libTensorFlowLiteQtVPlay.so] Error 1

I am the author of this tutorial. Could you try to compile TensorFlow with libstdc++ by using this command as described in the tutorial:
bazel build --cxxopt='--std=c++11' -c opt --config=android_arm tensorflow/lite/java:libtensorflowlite_jni
Maybe your problem is related to mixing libc++ and libstdc++, Qt uses libstdc++ and you are compiling TensorFlow with libc++ in your bazel command.
Let me know if this helps.

opencv jni build failed by using ndk (error: undefined reference)

OpenCV version = 3.1.0
Dlib version = 19.1
Android NDK version = r21
I would like to build lib.so file for Android Studio by using Android NDK. However, it failed in the SharedLibrary and OpenCV involved in all errors. I checked my directory path and it does not have any mistake. Can anyone tell help me?

Build opencv and tesseract for android-ndk

So I'm trying to build tesseract (using tess-two) and opencv for android. I'm able to build opencv and tess-two separately, but I want to be able to build them alongside.
For that I'm using the same build file as given in tess-two. Here all sub directory Android.mk files are called which works without a problem. As soon as I want to include the opencv library as well, and I want to compile files which are dependent on tesseract and opencv I get following errors.
Build command failed.

Android NDK: This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES
Android NDK: or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of the
Android NDK: current module
I'm not really sure, why this error happens. As mentioned I'm able to build the libraries separately. So the problem must be bringing them together.
Here is my makefile:
Android.mk:
LOCAL_PATH := $(call my-dir)
TESSERACT_PATH := $(LOCAL_PATH)/com_googlecode_tesseract_android/src
LEPTONICA_PATH := $(LOCAL_PATH)/com_googlecode_leptonica_android/src

LOCAL_LDLIBS := -llog -landroid -lcamera2ndk -lmediandk
LOCAL_SHARED_LIBRARIES := libtess liblept
include $(BUILD_SHARED_LIBRARY)
My current build directory looks as following:
- com_googlecode_leptonica_android
- com_googlecode_tesseract_android
- libjpeg
- libpng
- opencv
Is there something that I'm doing wrong? The error message is saying, that I'm using a non-system libraries in linker flags: -latomic , but this seems to be not the true error.
Can anyone help me?
Edit:
I found out, what the eror was. It was no rule to make target native_lib.cpp. So I wasn't able to build the following cpp file. I fixed it by creating a temporary variable of my $(LOCAL_PATH).
LOCAL_PATH := $(call my-dir)
MY_PATH := $(LOCAL_PATH)

Now, I'm running into a new problem.

Build issue : Android Link Error with AWS SDK CPP

I build (static and dynamic)the AWS SDK CPP library on my PC for Android Applications. After that, I developped an Android Application with Qt 5.10 using this AWS CPP librairy but at the end, during the link, I have many errors. I tried on MacOS and Windows 10 but I have the same errors and I used the ANDROID NDK 12 because is the only working to build the AWS SDK CPP library.
I tried to solve it during 2 weeks. Please Someone could help me ?
Here is my command of the linker and the result :

Android NDK and STL-related reference errors on x86

I'm building an integration with the V8 library. This builds works fine for ARM (armeabi, armeabi-v7a) targets.
I want to add x86 support. Today is the first time I've tried this.
I built V8 for x86 via make ia32.release.
My Application.mk is as follows:
APP_ABI := armeabi armeabi-v7a x86
APP_PLATFORM := android-14
APP_STL := stlport_static
and Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_libbase
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_libbase.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_base
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_base.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_nosnapshot
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_nosnapshot.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8_platform
LOCAL_SRC_FILES := ./libs/$(TARGET_ARCH_ABI)/libv8_libplatform.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := v8jsevaluator
LOCAL_SRC_FILES := v8jsevaluator.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include/
LOCAL_LDLIBS := -llog -landroid
LOCAL_STATIC_LIBRARIES := v8_base v8_nosnapshot v8_libbase v8_platform
LOCAL_CPP_FEATURES += exceptions
LOCAL_CFLAGS += -std=c++11
include $(BUILD_SHARED_LIBRARY)
The build fails in the x86 component with a lot of errors relating to STL.

As I said, without the attempt to build x86, this is all OK.
Please can anyone point me at where I'm going wrong? Thanks!

I upgraded my source of V8 from 4.1.0.22 to 4.9.385.30 and - after solving a lot of other issues - this problem went away.
