net-snmp中通过subagent方法，如何把多个Table编译成一个可执行文件？

Question

net-snmp中生成了多个XXX_Table.c和 XXX_Table.h的文件，这些代码都已经写好了。现在通过subagent的方法，想把这些表编译到一个文件来执行(运行该可执行几个Table表都能处理)，我按照网上的方法：

 #include <net-snmp/net-snmp-config.h>
#include <net-snmp/net-snmp-includes.h>
#include <net-snmp/agent/net-snmp-agent-includes.h>
#include <signal.h>

#include <nstAgentSubagentObject.h>

static int keep_running;

RETSIGTYPE
stop_server(int a) {
    keep_running = 0;
}

int
main (int argc, char **argv) {
  int agentx_subagent=1; /* change this if you want to be a SNMP master agent */
  int background = 0; /* change this if you want to run in the background */
  int syslog = 0; /* change this if you want to use syslog */

  /* print log errors to syslog or stderr */
  if (syslog)
    snmp_enable_calllog();
  else
    snmp_enable_stderrlog();

  /* we're an agentx subagent? */
  if (agentx_subagent) {
    /* make us a agentx client. */
    netsnmp_ds_set_boolean(NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_AGENT_ROLE, 1);
  }

  /* run in background, if requested */
  if (background && netsnmp_daemonize(1, !syslog))
      exit(1);

  /* initialize tcpip, if necessary */
  SOCK_STARTUP;

  /* initialize the agent library */
  init_agent("example-demon");

  /* initialize mib code here */

  /* mib code: init_nstAgentSubagentObject from nstAgentSubagentObject.C */
  init_nstAgentSubagentObject();  

  /* initialize vacm/usm access control  */
  if (!agentx_subagent) {
      init_vacm_vars();
      init_usmUser();
  }

  /* example-demon will be used to read example-demon.conf files. */
  init_snmp("example-demon");

  /* If we're going to be a snmp master agent, initial the ports */
  if (!agentx_subagent)
    init_master_agent();  /* open the port to listen on (defaults to udp:161) */

  /* In case we recevie a request to stop (kill -TERM or kill -INT) */
  keep_running = 1;
  signal(SIGTERM, stop_server);
  signal(SIGINT, stop_server);

  snmp_log(LOG_INFO,"example-demon is up and running.\n");

  /* your main loop here... */
  while(keep_running) {
    /* if you use select(), see snmp_select_info() in snmp_api(3) */
    /*     --- OR ---  */
    agent_check_and_process(1); /* 0 == don't block */
  }

  /* at shutdown time */
  snmp_shutdown("example-demon");
  SOCK_CLEANUP;

  return 0;
}

我通过init_agent("XXX1_table"); init_agent("XXX2_table"); ......init_agent("XXX7_table"); 这种方式编译不行。
打印：
ignoring extra call to init_agent (2)
ignoring extra call to init_agent (3)
ignoring extra call to init_agent (4)
ignoring extra call to init_agent (5)
ignoring extra call to init_agent (6)
ignoring extra call to init_agent (7)

我通过snmpset试了下，只能运行XXX1_table，后面的一个都不行。
不知道用什么方法来实现？我还需要存储其他一些额外的数据信息，所以没有使用静态或者动态的方法。
请高手指导下，谢谢！
