好家伙，不是做冰箱警察来着，给我干哪里去了。算了，C/C++就C/C++吧。
先自己完全做一个简单的，然后可以学习人家的工程代码，再整合成项目。
下载wiki里面的mpi的例程，我们来简化这个小工程。
先整代码，把cc文件从我们需要的工程源文件luckfox_mpi.cc和main.cc挪到项目目录的src文件夹，剩下的examples就删掉。
原来的例程里面有个菜单，我们给删掉然后把编译结果补上
build.sh
#!/bin/bash
#switch to the script's directory
ROOT_PWD=$(cd "$(dirname $0)" && pwd)
#clean build folder
if [ "$1" = "clean" ]; then
if [ -d "${ROOT_PWD}/build" ]; then
rm -rf "${ROOT_PWD}/build"
echo " ${ROOT_PWD}/build has been deleted!"
fi
if [ -d "${ROOT_PWD}/install" ]; then
rm -rf "${ROOT_PWD}/install"
echo " ${ROOT_PWD}/install has been deleted!"
fi
exit
fi
#clean build folder
if [ -d ${ROOT_PWD}/build ]; then
rm -rf ${ROOT_PWD}/build
fi
mkdir ${ROOT_PWD}/build
cd ${ROOT_PWD}/build
cmake ..
make install
#copy the install folder to the RV1106 board
adb shell ./oem/usr/bin/RkLunch-stop.sh
adb shell rm -rf /mnt/sdcard/
adb push ${ROOT_PWD}/install/MyMD_demo /mnt/sdcard/
adb shell chmod +x /mnt/sdcard/MyMD_demo/MyMD
adb shell ./mnt/sdcard/MyMD_demo/MyMD
同时我们更改一下cmake，把项目所依赖的环境变量删掉，替换成常量降低耦合性。其中有一个大坑，就是一定要在配置好工具链之后再配置项目名，不然会出现两个project并且在cmake时无限循环。可以遵循这样的思路：版本，基本变量，编译器，项目，检查文件夹，配置连接位置，配置安装位置，添加目标架构定义，配置第三方库， 配置源代码文件并可执行，目标链接库，头文件位置，安装目录和安装规则。
