libvalhalla cmake link static library Android

Directory pic:
This is how I compile protobuf:
export NDK=~/Android/Sdk/ndk/23.1.7779620
export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/linux-x86_64
export TARGET=x86_64-linux-android
export API=26
export AR=$TOOLCHAIN/bin/llvm-ar
export CC=$TOOLCHAIN/bin/$TARGET$API-clang
export AS=$CC
export CXX=$TOOLCHAIN/bin/$TARGET$API-clang++
export LD=$TOOLCHAIN/bin/ld
export RANLIB=$TOOLCHAIN/bin/llvm-ranlib
export STRIP=$TOOLCHAIN/bin/llvm-strip
export LDFLAGS="-llog -fPIC"
export CXXFLAGS="-fPIC"
../protobuf-3.19.0/configure --host $TARGET --disable-shared --with-pic
make -j$(nproc)
This is how I compile valhalla:
export PROTOBUF_INSTALL_DIR=/opt/protobuf
export PROTOBUF_HEADERS=$PROTOBUF_INSTALL_DIR/include
export PROTOC=$PROTOBUF_INSTALL_DIR/bin/protoc
export PROTOBUF_LIB=../protobuf_android/src/.libs # static libs that got generated from previous build script
export NDK=~/Android/Sdk/ndk/23.1.7779620
export TOOLCHAIN=$NDK/build/cmake/android.toolchain.cmake

clang++: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
I know it has to with linking dependencies but I don't know how to fix it, I've been trying to fix this for weeks now but with no success.
app/gradle.build
cmake {
arguments "-DCMAKE_BUILD_TYPE=Release"
cppFlags "-std=c++17", "-v"
abiFilters "x86_64"
}
Edit: Update stacktrace and CMakeLists.txt

From your build output it seems that some of the valhalla libraries depend on each other, and those dependencies are not reflected in your CMakeLists.txt. For example, the Tyr library seems to depend at least on the Baldr, Loki, Thor and Odin libraries (as can be seen from the names of the undefined symbols you get). To reflect this dependency you should add something like this to your CMakeLists.txt file:
target_link_libraries(valhalla-tyr PUBLIC
valhalla-baldr
valhalla-loki
valhalla-thor
valhalla-odin
)
If after applying this you get undefined symbols from other libraries you should also add similar dependencies for other Valhalla libraries.
As an effect of this, the linker will be passed a slightly different set of arguments, with some libraries possibly listed more than once or in a different order. This will help the linker find the missing symbols.
Another possible solution is to enclose Valhalla libraries within --start-group/--end-group arguments in your last target_link_libraries statement. This solution would be more compiler-dependent but if this CMakeLists file is only intended to be used for Android this might be fine:
target_link_libraries( react-native
-Wl,--start-group
libvalhalla
valhalla-baldr
# other valhalla libraries
-Wl,--end-group
# ...
)

in app build.gradle file, I set minSDKVersion to 30.
I think I should link a library about ImageDecoder or do something in my CMakeLists.txt.
but I'm not sure.
target_link_libraries(
native-lib
log
android
GLESv3
box2d)

You need to link jnigraphics.
For example:
target_link_libraries(
native-lib
log
android
GLESv3
box2d
jnigraphics)
There's an example at the image-decoder sample project.

Android Vulkan linker command failed

I'm trying to use Vulkan on Android so I had installed android ndk. I saw that in Android Studio default native C++, Vulkan is included. But whenever I build I get the following error:
C:/Users/a18/AndroidStudioProjects/vulkanSMD/app/src/main/cpp/native-lib.cpp:34:
error: undefined reference to 'vkCreateInstance' clang++: error:

I've tried including libvulkan.so and also tried dlopen("libvulkan.so", flags) but it is of no use.
I'm trying to get Vulkan working on android. The below code creates a vulkan instance.
#include <jni.h>
#include <string>
#include <vector>
#define VK_USE_PLATFORM_ANDROID_KHR 1
#include <vulkan/vulkan.h>

extensions = std::vector<const char *>({

"VK_KHR_surface",
});
layers = std::vector<const char *>({"VK_LAYER_LUNARG_standard_validation"});
VkInstanceCreateInfo createInfo = {};
VkApplicationInfo appInfo = {};
appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO;
appInfo.pApplicationName = "Vulkan is hard";
appInfo.applicationVersion = VK_VERSION_1_0;
appInfo.engineVersion = VK_VERSION_1_0;
appInfo.apiVersion = VK_VERSION_1_0 ;
createInfo.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
createInfo.pApplicationInfo = &appInfo;
createInfo.ppEnabledExtensionNames = extensions.data();
createInfo.enabledExtensionCount = static_cast<uint32_t>(extensions.size());
createInfo.ppEnabledLayerNames = layers.data();
createInfo.enabledLayerCount = static_cast<uint32_t>(layers.size());
VkInstance instance;
vkCreateInstance(&createInfo, nullptr, &instance);
std::string hello = "Hello from C++";
return env->NewStringUTF(hello.c_str());
}
While building however I get the following error

Using std::bad_function_call with LIBCPP_ABI_UNSTABLE

I am trying to build a native library in my Android Studio project that uses the std::bad_function_call function.
Here's the CMakeLists.txt file I use to build my native module:
cmake_minimum_required(VERSION 3.4.1)
include_directories(src/main/cpp)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-rtti -D_LIBCPP_ABI_UNSTABLE")
add_library(
MyLib
SHARED
src/main/cpp/test.cpp
)
and my test.cpp contains the following code:
void SomeClass::SomeMethod() {
std::function<int()> f = nullptr;
try {
f();
} catch (const std::bad_function_call& e) {
}
}
with the corresponding build.gradle section:
externalNativeBuild {
cmake {
arguments "-DANDROID_TOOLCHAIN=clang", "-DANDROID_STL=c++_static", "-DANDROID_NDK_ROOT=${android.ndkDirectory}"
}
}
If I pass the _LIBCPP_ABI_UNSTABLE flag to the compiler I get a link error:
Execution failed for task ':runtime:externalNativeBuildRelease'.
> Build command failed.

If I remove the _LIBCPP_ABI_UNSTABLE flag:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-rtti")
then the project compiles fine.
So my question is what would be the proper way to enable the libc++ unstable abi and use the bad_function_call method inside my native module?
Note: I am using Android NDK 19.

I got the same when building Boost 1.55.0 on Maverick with MacOSX10.7.sdk. So I added -I/usr/include to cflags and cxxflags options in my compile command. It resolved this problem. My full command.
