c - libmemcached 问题

Question

当我在我的 ubuntu 上运行 libmemcached 示例代码时，它给了我错误“对 `memcached_create' 的 undefined reference ”，任何人都可以帮忙吗？谢谢

#include <libmemcached/memcached.h>

int main(int argc, char **argv) {  
  //memcached_servers_parse (char *server_strings); 
  memcached_server_st *servers = NULL;
  memcached_st *memc;
  memcached_return rc;
  char *key= "keystring";
  char *value= "keyvalue";

  memc= memcached_create(NULL);
  servers= memcached_server_list_append(servers, "localhost", 11211, &rc);   rc= memcached_server_push(memc, servers);

  if (rc == MEMCACHED_SUCCESS)
    fprintf(stderr,"Added server successfully\n");   else
    fprintf(stderr,"Couldn't add server: %s\n",memcached_strerror(memc, rc));

  rc= memcached_set(memc, key, strlen(key), value, strlen(value), (time_t)0, (uint32_t)0);

  if (rc == MEMCACHED_SUCCESS)
    fprintf(stderr,"Key stored successfully\n");   else
    fprintf(stderr,"Couldn't store key: %s\n",memcached_strerror(memc, rc));

  return 0;

}

将 -lmemcached 传递给 GCC。这告诉它链接到 libmemcached.so 共享库。
