CMake错误:在EnableLanguage之后未设置CMAKE_C_COMPILER

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=}

我试图找到原因.

我找到了以下内容:

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).

似乎cmake有单独的版本3.5和3.6.

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 manager中再次安装它.

我还是这个:

Answer 1

您似乎正在使用不再支持某些ABI的NDK版本(错误日志中的armeabi),因此您必须将build.gradle(Project:....) 中的build升级到最新版本

classpath 'com.android.tools.build:gradle:3.1.3'

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

最后,你必须在你的build.gradle(模块:app)的 android块中添加abiFilters,具体取决于你需要的ABI:

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

Answer 2

在我的情况下,build.gradle(Module:app)中的更改后帮助我.

原版的

android {
 ....
    defaultConfig {
        externalNativeBuild {
            cmake {
                arguments '-DANDROID_STL=gnustl_static' ... [other args]
            }
        }
    }
 ....
}

随着我的变化

android {
 android.buildToolsVersion "28.0.3"
 ....
    defaultConfig {
        externalNativeBuild {
            cmake {
                '-DANDROID_STL=c++_static' ... [other args]
            }
        }
    }
 ....
}

Answer 3

我有同样的错误,我的ndk-bundle是最新的,它是ndk-r18b

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage  CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage Configuring incomplete, errors occurred!

我通过使用android-ndk-r14b修复它,你可以在其中指定它 local.properties

ndk.dir=/Users/xxxx/Library/Android/sdk/android-ndk-r14b

当然,你应该首先下载r14b,然后在sdk文件夹下解压缩它
