usTaskCheckFreeStackSpace undefined?

Posted by M J on October 27, 2008
I get an error when trying to compile the "ARM7_AT91SAM7X256_Eclipse" demo.

It states:
Description Resource Path LocationType ../../../Source/tasks.c undefined reference to usTaskCheckFreeStackSpace'RTOSDemo 1825 C/C++ Problem

Anybody know how to address this error? I cannot seem to figure out where I went wrong.

Thanks!

I went a head and tried all the other Eclipse demos. They gave me either that same error during compile or couldn't find the compiler "cs-make".

I'm assuming the other demos were not for Yagarto. Still stumped.

I got the same error compiling ARM7_LPC2368_Eclipse:

> make
../../../Source/tasks.o: In function `prvListTaskWithinSingleList':
...\freertos\Demo\ARM7_LPC2368_Eclipse\RTOSDemo/../../../Source/tasks.c:1825: undefined reference to `usTaskCheckFreeStackSpace'

I think the problem arises in the fact that the function is declared if ONE of the following macros is set to 1:

configUSE_TRACE_FACILITY == 1 || INCLUDE_uxTaskGetStackHighWaterMark == 1

The function is finally defined only if the INCLUDE_uxTaskGetStackHighWaterMark macro is set, but it is used in prvListTaskWithinSingleList, which is defined only if configUSE_TRACE_FACILITY is set.


I cannot test the following fix, but changing line 1835 of tasks.c from

#if ( INCLUDE_uxTaskGetStackHighWaterMark == 1 )

to

#if (configUSE_TRACE_FACILITY == 1) || ( INCLUDE_uxTaskGetStackHighWaterMark == 1 )

should fix this issue.

Somebody opened a bug report on this a couple of days ago. See
http://sourceforge.net/tracker/index.php?func=detail&aid=2194064&group_id=111543&atid=659633

I will try to get this fixed today if possible.

Regards.

This is now fixed in SVN and will get incorporated into the next release.

Regards.

I tried the fix recommended by cuffia on an LPC2138 board and it worked fine.
Thanks Cuffia.
