下面是移编译LWIP时出错！！！
LWIP/api_lib.c代码：
netconn *netconn_new_with_proto_and_callback(enum netconn_type t, u16_t proto,
                              void (*callback)(struct netconn *, enum netconn_evt, u16_t len))
{
struct netconn *conn;
struct api_msg *msg;
conn = memp_malloc(MEMP_NETCONN);
if (conn == NULL) {
return NULL;
}

conn->err = ERR_OK;
conn->type = t;
conn->pcb.tcp = NULL;
if ((conn->mbox = sys_mbox_new()) == SYS_MBOX_NULL) //提示：SYS_MBOX_NULL有问题？
{
memp_free(MEMP_NETCONN, conn);
return NULL;
}
conn->recvmbox = SYS_MBOX_NULL;
conn->acceptmbox = SYS_MBOX_NULL;
conn->sem = SYS_SEM_NULL;       提示：SYS_SEM_NULL有问题？
conn->state = NETCONN_NONE;
conn->socket = 0;
conn->callback = callback;
conn->recv_avail = 0;
if((msg = memp_malloc(MEMP_API_MSG)) == NULL) {
memp_free(MEMP_NETCONN, conn);
return NULL;
}

msg->type = API_MSG_NEWCONN;
msg->msg.msg.bc.port = proto; /* misusing the port field */
msg->msg.conn = conn;
api_msg_post(msg);
sys_mbox_fetch(conn->mbox, NULL);
memp_free(MEMP_API_MSG, msg);
if ( conn->err != ERR_OK ) {
memp_free(MEMP_NETCONN, conn);
return NULL;
}
return conn;
}
编译器是用的ADS1.2。
这是编译出错的提示:
