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?
This is the tutorial that I followed: https://www.youtube.com/watch?v=ZjZHiPWBiYY&t=2192s

How to compile LLVM/Clang for Android?

I'm trying to compile LLVM/Clang 8.0.1 for Android with Cmake (since autotools i used before are no longer supported) on mac.
I'm using https://github.com/llvm/llvm-project.git.
In build dir i'm using the following configure script (followed manuals):
cmake ../llvm \
-DCMAKE_INSTALL_PREFIX=/Users/asmirnov/Library/Android/llvm_android_arm \
-DLLVM_ENABLE_PROJECTS=clang \
-DLLVM_ENABLE_TERMINFO=OFF \
-DLLVM_ENABLE_THREADS=OFF \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_TARGETS_TO_BUILD="ARM;X86" \
-DLIBCLANG_BUILD_STATIC=ON \
-DLLVM_INCLUDE_TESTS=OFF \
-DLLVM_ENABLE_ZLIB=OFF \
\
-DCMAKE_CROSSCOMPILING=True \
-DLLVM_TABLEGEN=/Users/asmirnov/Library/Android/llvm/bin/llvm-tblgen \
-DCLANG_TABLEGEN=/Users/asmirnov/Documents/dev/src/llvm-project/build/bin/clang-tblgen \
-DLLVM_DEFAULT_TARGET_TRIPLE=arm-linux-gnueabihf \
-DLLVM_TARGET_ARCH=ARM \
-DBUILD_SHARED_LIBS=ON \
-DLLVM_ENABLE_PIC=False \
-DCMAKE_TOOLCHAIN_FILE=/Users/asmirnov/Library/Android/ndk/android-ndk-r20/build/cmake/android.toolchain.cmake
As you can see i'm using CMake toolchain file from Android NDK (20).
Also i've compiled it locally and passing LLVM_TABLEGEN and CLANG_TABLEGEN.
Configuration went successfully, but during the build i get the following errors:

Am i doing anything wrong? Is it LLVM/Clang bug? Any workaround?

I don't know if this is your only problem, but this is definitely wrong and could cause Clang to not find the right libraries:
-DLLVM_DEFAULT_TARGET_TRIPLE=arm-linux-gnueabihf
Android is arm-linux-androideabi$API_LEVEL. arm-linux-gnueabihf is a GNU/Linux target.

Yup, this requires some work arounds similar to this. Also use -DLLVM_DEFAULT_TARGET_TRIPLE="armv7a-linux-androideabi"

I experience the same error as has been described here: Android NDK make. Hundreds of "undefined reference error"s

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

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_CPPFLAGS := -std=c++11 -frtti -fexceptions
APP_ABI := armeabi armeabi-v7a mips x86 arm64-v8a x86_64 mips64
APP_PLATFORM := android-14
# use this to select gcc instead of clang
NDK_TOOLCHAIN_VERSION := 4.9

Linking to ceres library on Android

I'm trying to compile and deploy ceres solver into an Android project.
I successfully compiled ceres (1.8.0 and 1.9.0, tried both), running ndk-build from the ceres jni folder.
Then, I use QtCreator to compile and deploy and Android project. It fails with the following error:

I'm wondering if this could be due to ceres linking with c++ libraries statically, while my program links then dynamically....but have no clue how to solve this.

All libraries in your app SHOULD use the same STL runtime. But speaking about static libraries, they MUST use the same STL configuration. If you did not change cerces-solver/jni/Application.mk, it will expect APP_STL=c++_static. You can override this to use APP_STL=c++_shared, but you need a very good reason to change the way this external library is built. Much easier to switch your program to APP_STL=c++_static.
Edited by jpo38:
There are actually other things to be changed to have libceres.so be generated instead of libceres.a:
Add LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog in Android.mk
Replace include $(BUILD_STATIC_LIBRARY) by include $(BUILD_SHARED_LIBRARY) in Android.mk
Add -DCERES_BUILDING_SHARED_LIBRARY and -DCERES_RESTRICT_SCHUR_SPECIALIZATION (dunno why this second one helps, looks like Shur stuff does not like shared linkage) to LOCAL_CFLAGS in Android.mk
Then, the dynamic library is generated and may be used.
