Problems attempting to build oboe c++ library using cmake on windows

I am attempting to build 'oboe' on a windows machine using cmake (version 3.25.0) and a visual studio generator. The end goal is to create a c++ audio library that uses oboe as the back end for android, but as a first step simply geting oboe to build is the plan.
I have managed to succesfully generate build and use a static library with a few simple test functions using the method described below, but I run into errors when attempting to build oboe.
I have also managed to get oboe to build by using the method described in the documentation and
doing add_subdirectory etc. in the CMakeLists file of android studio. However I am trying to generate/ build using cmake outside of android studio.
The oboe repo is found here: https://github.com/google/oboe
The toolchain file I am using is: 'android.toolchain.cmake' included in the NDK at the location: ndk version/build/cmake/android.toolchain.cmake
I use a batch script to automate generating/ building to several different android ABI's, inspired by a similar shell script included with the oboe repo 'build_all_android.sh'. The .bat script I made is shown below:
#echo OFF

When I run this using the ANDROID_NDK variable (line 3) pointing to the root of the up to date ndk that comes with the visual studio 2022 android tools, I get an error:

CMake will not be able to correctly generate this project.
and cmake fails to generate the project. I can actually get this to generate correctly, but only if I set the android NDK version within the cross-compilation options of visual studio to use the NDK bundled with my installation of Android studio, and also set the ANDROID_NDK variable of the batch script to point to the same root.
In this case, though cmake generates the project the build fails with a similar reason to the warning given above:

Thanks in advance for any help, it is much appreciated!

Your build fails because you instruct the compiler to view the warning '__ANDROID_API__' macro redefined as an error. And this warning seems to occur because Visual Studio still sets the macro __ANDROID_API__ instead of setting __ANDROID_MIN_SDK_VERSION__. I think that is a Visual Studio bug that was introduced when they started shipping the NDK 23 instead of 21.
EDIT:
This issue is being tracked here.

Having trouble building a very simple OpenCV C++ .so library using CMake for use on Android

I am trying to use CMake to create a .so library that uses OpenCV for use on Android.
I have no prior experience with CMake before this. I got a couple things working with CMake so far. I successfully built and ran a simple OpenCV program for windows and I've also created a .so file that doesn't use OpenCV. I was able to successfully called that .so from a Unity program on Android. My goal is to create an OpenCV plugin for Unity. I turned to CMake because I tried making a simple .so in Visual Studios, but my Unity program couldn't find it (though I was able to create a .dll that used OpenCV for a windows Unity program using Visual Studios that worked).
I have both r19c Android NDK and OpenCV 4.5.2 Android SDK on my C drive.
My code file is test.cpp, and it very simply uses some OpenCV elements. It's as follows:
#include "opencv2/opencv.hpp"
extern "C" int get_number()
{
cv::Mat img(2,2, CV_8UC3, cv::Scalar(126,0,255));
cv::Size size = img.size();
int width = size.width;
return width;
}
I am thinking that my error may be in the CMakeLists.txt file, that I am probably pointing to the wrong OpenCV folders.
My CMakeLists.txt is:
cmake_minimum_required(VERSION 3.20)
set(OpenCV_DIR C:/OpenCVAndroid/sdk/native/jni/abi-arm64-v8a)
set(OpenCV_INCLUDE_DIRS C:/OpenCVAndroid/sdk/native/jni/include)
project( test )
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_library( test SHARED test.cpp )
and I'm using a .bat file that has the following lines:
rmdir /s /q build
mkdir build
cd build
"C:/Program Files/CMake/bin/cmake.exe" ^
-S=C:\Users\m_knu\Desktop\test ^
-G"MinGW Makefiles" ^

pause
all three files are located in the same folder.
When I run the .bat file I get the following output:

As I mentioned earlier, my guess is that I've incorrectly referenced the OpenCV directories, but I wouldn't be surprised if I'm missing other things.

NDK link C++ library .a error, no archive symbol table (run ranlib)

description
We have a C/C++ project wallet-core that is using third party library libsecp256k1, and we install libsecp256k1 into /usr/local/lib and /usr/local/include, all works well in wallet-core Unit Test, till we add it to android, which call wallet-core.
call links:
android project -> wallet-core -> trezor_crypto -> libsecp256k1
When we run tools/android-test, got error in link period:
xxxx -L/usr/local/lib trezor-crypto/libTrezorCrypto.a libprotobuf.a -llog /usr/local/lib/libsecp256k1.a -latomic -lm && :

clang++: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
Configuring for JNI
two function is undefined and there is no symbols, tell me ranlib. ranlib result:
$ranlib libsecp256k1.a
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive member: libsecp256k1.a(/0) size too large (archive member extends past the end of the file)
I run nm -g libsecp256k1.a also said it's truncated or malformed archive.
Please help me to solve this problem, we have stuck several days. Thanks a lot.
guess reason
I read many answer and guess it's reason:
linker will run ranlib before link, but it fail cause there is no
symbol ranlib failed because libsecp256k1.a
archive file is too big or maybe not in good format
libsecp256k1.a file is not
generated well or ranlib has problems.

How to use cmake from command line to make an executable for rooted Android device?

I want to run a simple executable that should print "Hello Cmake" when I will execute it from adb shell. For this, I have created a simple c++ file with CMakeLists.txt file as following:
hello.cpp
#include <iostream>
int main(int, char**) {
std::cout << "Hello, CMake!\n";
}
CMakeLists.txt
cmake_minimum_required(VERSION 3.4.1)
add_library( # Sets the name of the library.
hello_cmake
# Sets the library as a static library.
STATIC
# Provides a relative path to your source file(s).
hello.cpp )
I have tried to run following command in terminal:
cmake D:/Development/CMAKE/HelloCmake/ -G Ninja \
-DANDROID_TOOLCHAIN_NAME=aarch64-linux-android29-clang++ \
-DANDROID_PLATFORM=29 \
-DCMAKE_CACHEFILE_DIR=D:/Development/CMAKE/HelloCmake/build \

Any suggestion?
Update 2
I have run D:\Sdk\cmake\3.10.2.4988404\bin\ninja.exe -C arm64-v8a command to make the target static library but I get libhello_cmake.a which is current ar archive.
I think to make an executable the CMakeLists.txt add_library line should be replaced with something else?

There are a couple of problems:
Static libraries are not meant to be run directly. If you want to build an executable that you can run, you should use add_executable instead of add_library.
When you invoke cmake you should set the CMAKE_TOOLCHAIN_FILE option to specify the toolchain file to use, and possibly other options as well. To get an idea of what Android Studio / Gradle uses, you can use Android Studio's project wizard to create an Android project with C++ support and take a look at the cmake_build_command.txt file that gets generated when you build that project.
After running cmake you also need to run ninja. The command would be something like ninja -C <directory containing build files generated by cmake>.

CMake Project parsing failed.
I found several posts about this, but most of them were not answered or simply not useful. I found this helpful, so I added
SET (CMAKE_C_COMPILER_WORKS 1)
SET (CMAKE_CXX_COMPILER_WORKS 1)
before project(). But now I get
CMake Error in CMakeLists.txt:
No known features for CXX compiler
"Clang"
version 8.0.2.
CMake Project parsing failed.
So far I haven't found something useful for that.
I hope I can get some more help this way.
ps: I recently reinstalled my os (Windows 10), so if I forgot to update something it's not older than two month. I let QtCreator, Visual Studio and Android Studio do the installation of the toolchains.
pps: The project is a new project created by QtCreator
