设置编译器报错来提示相关性的东西用于一齐定义或设置
<设置编译报错>
使用预编译指令 #if (依据), #error "提示信息"
1 /* The timers module relies on xTaskGetSchedulerState(). */ 2 #if configUSE_TIMERS == 1 3 4 #ifndef configTIMER_TASK_PRIORITY 5 #error If configUSE_TIMERS is set to 1 then configTIMER_TASK_PRIORITY must also be defined. 6 #endif /* configTIMER_TASK_PRIORITY */ 7 8 #ifndef configTIMER_QUEUE_LENGTH 9 #error If configUSE_TIMERS is set to 1 then configTIMER_QUEUE_LENGTH must also be defined. 10 #endif /* configTIMER_QUEUE_LENGTH */ 11 12 #ifndef configTIMER_TASK_STACK_DEPTH 13 #error If configUSE_TIMERS is set to 1 then configTIMER_TASK_STACK_DEPTH must also be defined. 14 #endif /* configTIMER_TASK_STACK_DEPTH */ 15 16 #endif /* configUSE_TIMERS */
