Question

我第一次使用ACE（自适应通信环境）框架，并且在安装过程中苦苦挣扎。我从here下载了项目文件夹，然后使用了here上的说明。我在/ usr / include /文件夹中包含了'ace'文件夹。然后，我尝试编译该程序：

//client.cpp
#include <ace/Log_Msg.h>
#include <ace/SOCK_Connector.h>
static u_short SERVER_PORT = ACE_DEFAULT_SERVER_PORT;
static const char *const SERVER_HOST = ACE_DEFAULT_SERVER_HOST;
static const int MAX_ITERATIONS = 4;

int
main (int argc, char *argv[])
{
  const char *server_host = argc > 1 ? argv[1] : SERVER_HOST;
  u_short server_port = argc > 2 ? ACE_OS::atoi (argv[2]) : SERVER_PORT;
  int max_iterations = argc > 3 ? ACE_OS::atoi (argv[3]) : MAX_ITERATIONS;
  ACE_SOCK_Stream server;
  ACE_SOCK_Connector connector;
  ACE_INET_Addr addr (server_port,
                      server_host);
  if (connector.connect (server, addr) == -1)
    ACE_ERROR_RETURN ((LM_ERROR,
                       "%p\n",
                       "open"),
                      -1);
  for (int i = 0; i < max_iterations; i++)
    {
      char buf[BUFSIZ];

      /* Create our message with the message number */
      ACE_OS::sprintf (buf,
                       "message = %d\n",
                       i + 1);

      if (server.send_n (buf,
                         ACE_OS::strlen (buf)) == -1)
        ACE_ERROR_RETURN ((LM_ERROR,
                           "%p\n",
                           "send"),
                          -1);
      else
        /* Pause for a second.  */
        ACE_OS::sleep (1);
    }

  if (server.close () == -1)
    ACE_ERROR_RETURN ((LM_ERROR,
                       "%p\n",
                       "close"),
                      -1);
  return 0;
}

与g++ client.cpp一起使用后，出现以下错误：

/tmp/ccsSpahN.o: In function `main':
client.cpp:(.text+0xe3): undefined reference to `ACE_INET_Addr::ACE_INET_Addr(unsigned short, char const*, int)'

所以我的问题是：

为什么会出现此错误。我想走哪一步？
编译时需要链接哪个库？请提供语法。

编辑：在评论部分中，我正在编辑此问题。看到错误后，很明显该错误是由于在使用g ++进行编译时未链接到某个库而引起的。我在第二个问题中明确指出了这一点。我想知道在编译过程中需要添加的-l（某些库）选项是什么。
