系统环境：mac os
运行条件: 安装cmake 和 下载ndk
创建文件

# cmake -DCMAKE_TOOLCHAIN_FILE=/Users/Shared/ShareLib/Android/sdk/ndk-bundle/build/cmake/android.toolchain.cmake ..
编译工程
创建build目录并进入
在build目录下执行cmake
cmake -DCMAKE_TOOLCHAIN_FILE=/Users/Shared/ShareLib/Android/sdk/ndk-bundle/build/cmake/android.toolchain.cmake ..
其中"/Users/Shared/ShareLib/Android/sdk/ndk-bundle/build/cmake/android.toolchain.cmake"是本机机器ndk安装交互编译的cmake配置
输出

由此可以知道目前是使用clang进行编译
此时执行 make ，输出

以上hello即为可在安卓上执行的文件
执行文件
将hello文件push到手机的/data/local/tmp/目录下
运行文件
adb shell
cd /data/local/tmp/
./hello
则得到以下输出
