Hi all,
I'm new and I would use FreeRTOS on STR912FA with IAR compiler. I downloaded the last version (5.1.0) and the compiler gives this error:

Error[Li005]: no definition for "usTaskCheckFreeStackSpace" [referenced from C:\Documents and Settings\paolo\Documenti\str912\RTOS\FreeRTOSV5.1.0\
FreeRTOSV5.1.0\FreeRTOS\Demo\ARM9_STR91X_IAR\ARM - uIP - D\Obj\tasks.o]


In the file task.c I saw that the definition of the prototype "usTaskCheckFreeStackSpace" is different from that of the function


#if ( ( configUSE_TRACE_FACILITY == 1 ) || ( INCLUDE_uxTaskGetStackHighWaterMark == 1 ) ) <------- Different ******

unsigned portSHORT usTaskCheckFreeStackSpace( const unsigned portCHAR * pucStackByte );

#endif


#if ( INCLUDE_uxTaskGetStackHighWaterMark == 1 ) <------- Different ******

unsigned portSHORT usTaskCheckFreeStackSpace( const unsigned portCHAR * pucStackByte )
{
register unsigned portSHORT usCount = 0;

while( *pucStackByte == tskSTACK_FILL_BYTE )
{
pucStackByte -= portSTACK_GROWTH;
usCount++;
}

usCount /= sizeof( portSTACK_TYPE );

return usCount;
}

#endif


Setting them equal everything works properly, or should I set "INCLUDE_uxTaskGetStackHighWaterMark" to 1?
What is the correct thing to do?

Thanks for your answer
Paolo Ferrari

There is an inconsistency introduced in 5.10 in the macros that include functions that rely on each other. There is a bug report in the tracker for this issue and it is noted on the known issues list with the fix given. I think the SVN version has a fix as well.

Thanks woops,

I look the tracker
