compile problem

Dear Sir:
  Really sorry to bother you,However,when I compile the gflags(2.1.1),I found a error occured. I have utilized the cmake ., make && make install comond to prepare the environment. it says like following:

Scanning dependencies of target gflags-static
[ 16%] Building CXX object CMakeFiles/gflags-static.dir/src/gflags.cc.o

-- Installing: /usr/local/bin/gflags_completions.sh

Besides that, I wrote a simple code(named demo.c) to test that.The source code 
looks like following:

#include <iostream>
#include <gflags/gflags.h>

DEFINE_bool(isvip, false, "If Is VIP");
DEFINE_string(ip, "127.0.0.1", "connect ip");
DECLARE_int32(port);
DEFINE_int32(port, 80, "listen port");

int main(int argc, char** argv)
{
  google::ParseCommandLineFlags(&argc, &argv, true);
  std::cout<<"ip:"<<FLAGS_ip<<std::endl;
  std::cout<<"port:"<<FLAGS_port<<std::endl;
  if (FLAGS_isvip)
  {
      std::cout<<"isvip:"<<FLAGS_isvip<<std::endl;
  }
  google::ShutDownCommandLineFlags();
  return 0;
}

After that. I utilized the following command to compile :

g++ -o demo demo.c -L/home/hon/Desktop/gflags-2.1.0/lib -lgflags 
-I/home/hon/Desktop/gflags-2.1.0/include/

However, it says :

demo.c: In function ‘int main(int, char**)’:
demo.c:11:3: error: ‘google’ has not been declared
   google::ParseCommandLineFlags(&argc, &argv, true);
   ^
demo.c:18:3: error: ‘google’ has not been declared
   google::ShutDownCommandLineFlags();

could you give a favor and let me know what's wrong? Thank you very much.

This error relates to the change of the default namespace from "google" to 
"gflags" with release of version 2.1. The problem will be fixed in the next 
release 2.1.2 (cf. issue 83).

Change "google::" in your demo.c to "gflags::" and try again.
