Почему я все еще получаю неопределенные ошибки ссылок, связывающих статическую библиотеку с CMake в Android NDK?

/ 04 октября 2018

При создании следующего проекта Android-NDK я получаю десятки неопределенных ошибок ссылок относительно отсутствующих стандартных функций библиотеки.Я следовал некоторым базовым примерам связывания статических библиотек и перезапускал этот проект с нуля 3 раза, но все еще не могу найти проблему.Я пытаюсь использовать библиотеку lib_seal, скомпилированную с использованием -std=c++1z.(https://www.microsoft.com/en-us/research/project/simple-encrypted-arithmetic-library/).

Ошибки, которые я получаю, указывают на то, что библиотека связана правильно, но по многим ссылкам в Интернете она не может найти -lstdc++ (Один пример, рекомендующий это здесь: неопределенная ссылка на`std :: ios_base :: Init :: Init () '). Я добавил это в свой файл CMakeLists.txt под target_link_libraries, и я попытался отредактировать файл Gradle, чтобы включить cppFlags = "-std=c++1z", "-std=c++11", "-lstdc++" и т. Д. Я также попытался добавить arguments "-DANDROID_STL=c++_shared".

Ниже приведено самое близкое к нему, что я могу получить для компиляции и ссылки:

CMakeLists.txt: 

# Sets the minimum version of CMake required to build the native library.

cmake_minimum_required(VERSION 3.4.1)

add_library(lib_seal STATIC IMPORTED)

# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.

add_library( # Sets the name of the library.
        native-lib

        # Sets the library as a shared library.
        SHARED

        # Provides a relative path to your source file(s).
        src/main/cpp/native-lib.cpp)

# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.

find_library( # Sets the name of the path variable.
        log-lib

        # Specifies the name of the NDK library that
        # you want CMake to locate.
        log)

set_target_properties(lib_seal PROPERTIES IMPORTED_LOCATION
        ${CMAKE_SOURCE_DIR}/libs/seal/${ANDROID_ABI}/lib/libseal.a)

target_include_directories(native-lib PRIVATE
        ${CMAKE_SOURCE_DIR}/libs/seal/${ANDROID_ABI}/include)

# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.

target_link_libraries(native-lib

        lib_seal

Всего парапримечания: мне нужно использовать -std=c++1z, чтобы использовать библиотеку SEAL (или -std=gnu++1z), и ближе к концу файла Gradle я специально разрешаю только архитектуру x86_64, так как не хочу беспокоиться о кросс-компиляции чего-либо доЯ получаю это работает.

Похоже, что libseal был построен с более старым NDK с использованием GNU libstdc ++ (gnustl на языке NDK).Libstdc ++ GNU больше не включен в NDK r18.Вам нужно либо пересобрать libseal с помощью libc ++, либо понизить ваш NDK.
