MQX轻量级日志怎么用？

user_config.h 已经定义为1了：#define MQX_USE_LWLOGS 1

void task_lwlog(uint32_t initial_data)
{
   uint32_t led[5]={0x11,0x22,0x33,0x44,0x55};
   LWLOG_ENTRY_STRUCT entry;
   _lwlog_create_component(); //创建日志组件
   _lwlog_create(1,10,1);
   _lwlog_write(1,led[0],led[1],led[2],led[3],led[4],0);

while(1)
{
   _lwevent_wait_for(&lwevent_group, event_lwlog, FALSE, NULL);
                        _lwlog_read(1,LOG_READ_OLDEST,&entry);
   printf("%x,%x,%x,%x,%x",entry.DATA[0],entry.DATA[1],entry.DATA[2],entry.DATA[3],entry.DATA[4]);

   _lwevent_clear(&lwevent_group,event_di);

   }
}

编译后：
E:\MQX软件学习\mqx4.1.1.0\mqx\examples\wdwkzq2\task_lwlog.c(7): error:  #20: identifier "LWLOG_ENTRY_STRUCT" is undefined
               LWLOG_ENTRY_STRUCT entry;

感觉应该还有别的什么要配置？求教各位大佬。
