FreeRTOS V8.1.2 compile error

Posted by hpipon on July 2, 2015

Hello I wanted to compile FreeRTOS V8.1.2 with Keil ┬ÁVision but I got an error : > #if( configMAXPRIORITIES > 32 ) > ..srcportableRVDSARMCM4Fportmacro.h(148): error: #18: expected a ")"

I saw a difference in the file portmacro.h now there is

/* Port specific optimisations. */ #ifndef configUSEPORTOPTIMISEDTASKSELECTION #define configUSEPORTOPTIMISEDTASKSELECTION 1 #endif

#if configUSE_PORT_OPTIMISED_TASK_SELECTION == 1

/* Check the configuration. */
#if( configMAX_PRIORITIES > 32 )

The cast inside configMAX_PRIORITIE definition generates the error ....


FreeRTOS V8.1.2 compile error

This is presumably because of the configMAX_PRIORITIES definition in FreeRTOSConfig.h.

[as you say] Ensure the definition does not contain a cast. For example, the following will be ok:

#define configMAX_PRIORITIES ( 8 )

whereas the following would not be ok:

#define configMAX_PRIORITIES ( ( UBaseType_t ) 8 )
