1、protobuf
网址：https://github.com/protocolbuffers/protobuf/releases
下载版本：protobuf-all-3.6.1.tar.gz
首先安装pc版本，
protoc –version 测试，如果提示缺少库，从/usr/local/lib目录拷贝到/usr/lib目录
PC安装protobuf
./configure
make -j4
sudo make install
arm编译protobuf
./configure --host=arm-linux-gnueabihf --with-protoc=protoc --prefix=/home/Your Name/dependLib/protobuf-3.6./
make -j4
make install
在 protobuf-3.6.1 目录下生成include和lib文件夹，就是需要的头文件和库
