which version of protoc can be used in this project?

At first, I install protoc-2.6.1, but I get an error:

In file included from .build_release/src/caffe/proto/caffe.pb.cc:4:0:
.build_release/src/caffe/proto/caffe.pb.h:12:2: error: #error This file was generated by a newer version of protoc which is

compilation terminated.
Makefile:582: recipe for target '.build_release/src/caffe/proto/caffe.pb.o' failed
make: *** [.build_release/src/caffe/proto/caffe.pb.o] Error 1

Then I install protoc-3.6.1 instead, but the error still exists.

I think this is because the protocol compiler (protoc) and the library header (/usr/include/google/protobuf) are inconsistent.

% protoc --version
libprotoc 3.6.1
% grep GOOGLE_PROTOBUF_VERSION /usr/include/google/protobuf/stubs/common.h
#define GOOGLE_PROTOBUF_VERSION 2006001

I am not the user of root, and the protoc is installed at my own dir.
So anyone could help me solve this problem?
Thanks!
