2 解决方法
可以看到这个文件是编译caffe时候生成的，并且它所要求的protobuf版本是2.6.0或2.6.1，高于或低于都会出现error
此时需要查看系统的protobuf的版本是多少：
命令行输入 protoc --version
显示：libprotoc 3.5.0
确实因为某次升级将protobuf的版本升级到了3.5.0，所以产生了上述error。
解决方案：
在caffe目录下重新编译：
make clean
make all -j4
然后如果需要将caffe相关的内容安装到系统目录则：
sudo make install
此时再次编译原来的工程，error消失，编译通过。
