android - 启用语言后 CMake 错误 : CMAKE_C_COMPILER not set,

Question

当我构建一个包含 ndk 代码的 android 项目时。我收到以下错误:

Build command failed. 
Error while executing process /home/gongzelong/Android/Sdk/cmake/3.6.4111459/bin/cmake with arguments {-H/media/gongzelong/TOSHIBA/Code/Code/ImageLoaderEncapsulation/ImageLoader/ImageLoaderDemo/app -B/media/gongzelong/TOSHIBA/Code/Code/ImageLoaderEncapsulation/ImageLoader/ImageLoaderDemo/app/.externalNativeBuild/cmake/debug/armeabi -GAndroid Gradle - Ninja -DANDROID_ABI=armeabi -DANDROID_NDK=/home/gongzelong/Android/Sdk/ndk-bundle -DCMAKE_LIBRARY_OUTPUT_DIRECTORY=/media/gongzelong/TOSHIBA/Code/Code/ImageLoaderEncapsulation/ImageLoader/ImageLoaderDemo/app/build/intermediates/cmake/debug/obj/armeabi -DCMAKE_BUILD_TYPE=Debug -DCMAKE_MAKE_PROGRAM=/home/gongzelong/Android/Sdk/cmake/3.6.4111459/bin/ninja -DCMAKE_TOOLCHAIN_FILE=/home/gongzelong/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake -DANDROID_PLATFORM=android-14 -DCMAKE_CXX_FLAGS=}

我试着找出原因。

我发现了以下内容:

gongzelong@gongzelong:~/Android/Sdk/cmake/3.6.4111459/bin$ cmake -version
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/home/gongzelong/Android/Sdk/cmake/3.6.4111459/share/cmake-3.5
cmake version 3.5.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).

好像cmake有3.5和3.6的版本。

谁能指出如何修复它并成功构建 android 项目？

更新:

我删除了 cmake 并在 android studio sdk 管理器中重新安装它。

我还有这个:

Answer 1

似乎您使用的 NDK 版本不再支持某些 ABI(错误日志中的 armeabi)，因此您必须升级 build.gradle (Project:....)到最新的

类路径'com.android.tools.build:gradle:3.1.3'

并且在 gradle-wraper.properties 中:distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

最后，您必须根据需要的 ABI 在 build.gradle(Module:app) 的 android block 中添加 abiFilters:

android {
 ....
    defaultConfig {
        externalNativeBuild {
            cmake {
                abiFilters 'arm64-v8a', 'armeabi-v7a', 'x86', 'x86_64'
            }
        }
    }
 ....
}
