java - 不再支持 Android NDK APP_STL gnuSTL_shared

Question

我正在使用 Android Studio 3.3 Canady 11 构建一个 android NDK 项目，在构建项目时，我收到了这个错误:

Build command failed. Error while executing process /home/ndqa/opt/Android-SDK/ndk-bundle/ndk-build with argument {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/home/ndqa/Documents/PROJ/code/MyProj/app/src/main/cpp/Android.mk NDK_APPLICATION_MK=/home/ndqa/Documents/PROJ/code/MyProj/app/src/main/cpp/Application.mk APP_ABI=armeabi-v7a NDK_ALL_ABIS=armeabi-v7a NDK_DEBUG=1 APP_PLATFORM=android-23 NDK_OUT=/home/ndqa/Documents/PROJ/code/MyProj/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=/home/ndqa/Documents/PROJ/code/MyProj/app/build/intermediates/ndkBuild/debug/lib APP_PLATFORM=android-21 -j10 APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n}

/home/ndqa/opt/Android-SDK/ndk-bundle/build/core/add-application.mk:178: *** Android NDK: APP_STL gnustl_shared is no longer supported. Please switch to either c++_static or c++_shared. See https://developer.android.com/ndk/guides/cpp-support.html for more information. . Stop.

我的机器是 Ubuntu 18，它有 android SDK，完整的 NDK。 请帮我解决这个问题。 谢谢大家!

更新 如果我用 c++_static 或 c++_shared 替换 gnuSTL_shared，它会显示更多错误:

Answer 1

1. 在文件 Application.mkAPP_STL := gnuSTL_static 切换为 c++_static 或 c++_shared

APP_STL := c++_static

1. 几年前，Android 操作系统切换为 clang。 NDK 的 future 版本将移除 GCC，因此您越早开始使用 clang 测试您的项目越好!

1. For ndk-build, remove lines setting NDK_TOOLCHAIN or NDK_TOOLCHAIN_VERSION.

2. For cmake, remove lines setting ANDROID_TOOLCHAIN.

3. For standalone toolchains, use the clang/clang++ binaries instead of gcc/g++.

4. For other build systems, ask the owners of that build system.
