error: implicit declaration of function ‘xTaskNotifyStateClear’; did you mean ‘xTaskNotifyWait’? [-Werror=implicit-function-declaration]
why am i receiving this error when the other task macros are present like xTaskNotifyFromISR?

The macro is here: https://github.com/FreeRTOS/FreeRTOS-Kernel/blob/V10.4.1-kernel-only/include/task.h#L2622
and the function it calls is here
}
}
portCLEAR_INTERRUPT_MASK_FROM_ISR( uxSavedInterruptStatus );
}
#endif /* configUSE_TASK_NOTIFICATIONS */
/*-----------------------------------------------------------*/
#if ( configUSE_TASK_NOTIFICATIONS == 1 )
BaseType_t xTaskGenericNotifyStateClear( TaskHandle_t xTask,
UBaseType_t uxIndexToClear )
{
TCB_t * pxTCB;
BaseType_t xReturn;
configASSERT( uxIndexToClear < configTASK_NOTIFICATION_ARRAY_ENTRIES );
/* If null is passed in here then it is the calling task that is having
* its notification state cleared. */
pxTCB = prvGetTCBFromHandle( xTask );
Looks like configUSE_TASK_NOTIFICATIONS is the only conditional compilation required - do you have that set to 1 in FreeRTOSConfig.h? (or left undefined, as I think it defaults to 1)?
