Google Protocol Buffers. C++ error: 'protobuf' does not name a type

I have the following code which I'm really struggling to compile:

#include <stdio.h>
#include <stdlib.h>
#include "test.pb.h"

using namespace google::protobuf;
using namespace std;


protobuf::RpcChannel* channel;   //error on this line!

I keep getting this 'protobuf' does not name a type error. I have no idea how to fix this ;(

An开发者_运维百科y insight greatly appreciated.

Many thanks in advance,

There is no protobuf namespace, since you did using namespace google::protobuf (which you shouldn't). Do namespace protobuf = google::protobuf instead.

You need to include #include "google\protobuf\service.h" in the file you are using RpcChannel not in the headers.
