Describe the bug
I try to test code in the example markdown as :

#include <cpp_redis/cpp_redis>

#include <iostream>

#ifdef _WIN32
#include <Winsock2.h>
#endif /* _WIN32 */

int
main(void) {
#ifdef _WIN32
  //! Windows netword DLL init
  WORD version = MAKEWORD(2, 2);
  WSADATA data;

  if (WSAStartup(version, &data) != 0) {
    std::cerr << "WSAStartup() failure" << std::endl;
    return -1;
  }
#endif /* _WIN32 */

  //! Enable logging
  cpp_redis::active_logger = std::unique_ptr<cpp_redis::logger>(new cpp_redis::logger);

  cpp_redis::client client;

  client.connect("127.0.0.1", 6379, [](const std::string& host, std::size_t port, cpp_redis::client::connect_state status) {
    if (status == cpp_redis::client::connect_state::dropped) {
      std::cout << "client disconnected from " << host << ":" << port << std::endl;
    }
  });

  // same as client.send({ "SET", "hello", "42" }, ...)
  client.set("hello", "42", [](cpp_redis::reply& reply) {
    std::cout << "set hello 42: " << reply << std::endl;
    // if (reply.is_string())
    //   do_something_with_string(reply.as_string())
  });

  // same as client.send({ "DECRBY", "hello", 12 }, ...)
  client.decrby("hello", 12, [](cpp_redis::reply& reply) {
    std::cout << "decrby hello 12: " << reply << std::endl;
    // if (reply.is_integer())
    //   do_something_with_integer(reply.as_integer())
  });

  // same as client.send({ "GET", "hello" }, ...)
  client.get("hello", [](cpp_redis::reply& reply) {
    std::cout << "get hello: " << reply << std::endl;
    // if (reply.is_string())
    //   do_something_with_string(reply.as_string())
  });

  // commands are pipelined and only sent when client.commit() is called
  // client.commit();

  // synchronous commit, no timeout
  client.sync_commit();

// synchronous commit, timeout
// client.sync_commit(std::chrono::milliseconds(100));

#ifdef _WIN32
  WSACleanup();
#endif /* _WIN32 */

  return 0;
}

I follow the command line in
https://github.com/cpp-redis/cpp_redis/wiki/Mac-&-Linux-Install
to install cpp_redis

and use

gcc -lstdc++ -lcpp_redis -ltacopie --std=c++11 test_redis.cpp -o testredis

to compile the code.

But it come out a error ：

bash-5.0# gcc -lstdc++ -lcpp_redis -ltacopie --std=c++11 test_redis.cpp -o testredis

To Reproduce
Steps to reproduce the behavior:

  1. follow https://github.com/cpp-redis/cpp_redis/wiki/Mac-&-Linux-Install to install cpp_redis
  2. copy code in https://github.com/cpp-redis/cpp_redis/wiki/Examples#redis-client to a file(test_redis.cpp)
  3. try gcc -lstdc++ -lcpp_redis -ltacopie --std=c++11 test_redis.cpp -o testredis to compile

Expected behavior
compile success with no error or warning.

I find that the connect_state is actually define under cpp_redis namespace, and I change the code to

client.connect("127.0.0.1", 6379, [](const std::string& host, std::size_t port, cpp_redis::connect_state status) {                           
  if (status == cpp_redis::connect_state::dropped) {                                                                                   
std::cout << "client disconnected from " << host << ":" << port << std::endl;                                                        
  }                                                                                                                                    
});

and try to use gcc -lstdc++ -lcpp_redis -ltacopie --std=c++11 test_redis.cpp -o testredis again.
And I got:

bash-5.0# gcc -lstdc++ -lcpp_redis -ltacopie --std=c++11 test_redis.cpp -o testredis
