I have simple Gradle project and trying to add native library building it using CMake
Root CMakeLists.txt
project(mine_lib)
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
set(EXECUTABLE_OUTPUT_PATH "${PROJECT_SOURCE_DIR}/bin")
configure_file("${PROJECT_SOURCE_DIR}/src/buildinfo/buildinfo.hpp.in" "${PROJECT_BINARY_DIR}/buildinfo.hpp")
set(CMAKE_VERBOSE_MAKEFILE on)
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${warnings}")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${warnings}")
add_subdirectory(${PROJECT_SOURCE_DIR}/src)
include_directories(${PROJECT_SOURCE_DIR}/src/data)
include_directories("${PROJECT_BINARY_DIR}")
add_library(mine_lib SHARED "${PROJECT_SOURCE_DIR}/src/jni/jniwrapper.c")
build.gradle
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "..."
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
defaultConfig {
externalNativeBuild {
cmake {
arguments "-DANDROID_STL=system"
cppFlags "-fexceptions"
}
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {
path "src/main/mine_lib/CMakeLists.txt"
}
}
sourceSets {
main {
jniLibs.srcDirs 'src/main/mine_lib/src/'
}
}
}
In my native library I use part of STL library, for example cstdint
. And for now I'm getting compilation error which looks like that:
Error:FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:externalNativeBuildDebug'.
> Build command failed.

What is the problem really is and how can I solve it?
Based on my understanding the problem could be solved by using a different C++ Library.
Currently you are specifying the following within the build.gradle
file:
arguments "-DANDROID_STL=system"
Which, as stated within the following documentation , is:
system: The minimal system C++ runtime library and the default runtime
You'll probably need to change that to another C++ Library but I am not sure which one it would be, could be one of the gnu options. Better yet, it could be solved by removing the statement entirely.
