說明
系統(tǒng)環(huán)境：mac os
運(yùn)行條件: 安裝cmake 和 下載ndk
創(chuàng)建文件
源文件 hello.cpp
#include<stdio.h>
int main(){
printf("hello world \n");
return 0;
}
CMakeCache.txt 文件
cmake_minimum_required(VERSION 3.7)
#include(/Users/Shared/ShareLib/Android/sdk/ndk-bundle/build/cmake/android.toolchain.cmake)

# cmake -DCMAKE_TOOLCHAIN_FILE=/Users/Shared/ShareLib/Android/sdk/ndk-bundle/build/cmake/android.toolchain.cmake ..
編譯工程
創(chuàng)建build目錄并進(jìn)入
在build目錄下執(zhí)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"是本機(jī)機(jī)器ndk安裝交互編譯的cmake配置

此時(shí)執(zhí)行 make 掘剪，輸出
Scanning dependencies of target hello

以上hello即為可在安卓上執(zhí)行的文件
執(zhí)行文件
將hello文件push到手機(jī)的/data/local/tmp/目錄下
運(yùn)行文件
adb shell
cd /data/local/tmp/
./hello
則得到以下輸出
