Hi @ivanarh , I am trying to add libunwind-ndk in my project with the help of https://github.com/ivanarh/nativecrashes. Getting this error can your please help.

Build command failed.

Here is my build.gradle configuration for ndk: defaultConfig { applicationId = 'com.example.hellolibs' minSdkVersion 14 targetSdkVersion 25 versionCode = 1 versionName = '1.0' externalNativeBuild { cmake { arguments "-DANDROID_PLATFORM=android-15", '-DANDROID_TOOLCHAIN=clang', '-DANDROID_STL=gnustl_static', "-DANDROID_ARM_MODE=arm", "-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON" } } ndk { abiFilters "x86", "armeabi", "armeabi-v7a" } } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } sourceSets { main { // let gradle pack the shared library into apk jniLibs.srcDirs = ['../distribution/gperf/lib'] } } externalNativeBuild { cmake { path 'src/main/cpp/CMakeLists.txt' } }

and CMakeLists.txt is `cmake_minimum_required(VERSION 3.4.1)

libunwind start

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -fno-optimize-sibling-calls -fno-inline") set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -fno-optimize-sibling-calls -fno-inline")

add_subdirectory(src/main/cpp/external/libunwind/cmake) include_directories(src/main/cpp/external/libunwind/include)

find_library(log-lib log)

libunwind end

set(distribution_DIR ${CMAKE_SOURCE_DIR}/../../../../distribution)

add_library(lib_gmath STATIC IMPORTED) set_target_properties(lib_gmath PROPERTIES IMPORTED_LOCATION ${distribution_DIR}/gmath/lib/${ANDROID_ABI}/libgmath.a)

add_library(lib_gperf SHARED IMPORTED) set_target_properties(lib_gperf PROPERTIES IMPORTED_LOCATION ${distribution_DIR}/gperf/lib/${ANDROID_ABI}/libgperf.so)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")

add_library(test1 SHARED test1.cpp Demo.cpp native-lib.c )

target_include_directories(test1 PRIVATE ${distribution_DIR}/gmath/include ${distribution_DIR}/gperf/include)

target_link_libraries(test1 ${log-lib} unwind android lib_gmath lib_gperf log) `

Please suggest, I am stuck from several days. Thanks in advance!

Getting this, please check

CMake Error at CMakeLists.txt:7 (add_subdirectory):

[ivanarh]

Try git submodule update --init --recursive Libunwind requires lzma library which is added as a submodule, i suspect you didn't fetch it.

[deepakrokz]

I am adding complete source code of this https://github.com/ivanarh/libunwind-ndk/tree/58d2371c86789c2cc591be116348147bcca34cf1 in this location

src/main/cpp/external/libunwind/

why do I need to run this command when it's not synced with Github link, so not able to run the command

[ivanarh]

You should either clone libunwind-ndk repository as a submodule or manually clone https://android.googlesource.com/platform/external/lzma repository to lzma folder in libunwind-ndk root.

[deepakrokz]

I did the manual clone of Lzma and added in the root of libunwind-ndk root but still getting this

CMake Error at CMakeLists.txt:7 (add_subdirectory):

[ivanarh]

Please add CMAKE_VERBOSE_MAKEFILE argument to your build.gradle, it should be something like this:

android {
    ...
    defaultConfig {
       ...
        externalNativeBuild {
            cmake {
                arguments "-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON"
            }
        }

After that run build from console: ./gradlew assembleDebug

And attach a full build output.

[deepakrokz]

I tried as you suggested but no luck, earlier I was trying with this argument

arguments '-DANDROID_PLATFORM=android-15', '-DANDROID_ARM_MODE=arm', '-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON', '-DANDROID_TOOLCHAIN=clang', '-DANDROID_STL=gnustl_static'

Hi @ivanarh ,

can you please help me out of this, please.

[ivanarh]

I can't help you without a full build log. If you can't build an app from console you can attach a following file:

D:/MyWorkspace/hello-libs/app/.externalNativeBuild/cmake/release/armeabi-v7a/CMakeFiles/CMakeOutput.log

I hope it would help.

[deepakrokz]

Thanks for your time and reply, CMakeOutput.log here is the file you are asking for:

Hi @ivanarh , Have you found anything?
