[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [October 2008 Threads] 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!
RE: usTaskCheckFreeStackSpace undefined?Posted by M J on October 27, 2008 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.
RE: usTaskCheckFreeStackSpace undefined?Posted by Claudio Destro on October 27, 2008 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.
RE: usTaskCheckFreeStackSpace undefined?Posted by Richard on October 29, 2008 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.
RE: usTaskCheckFreeStackSpace undefined?Posted by Richard on October 29, 2008 This is now fixed in SVN and will get incorporated into the next release.
Regards.
RE: usTaskCheckFreeStackSpace undefined?Posted by Tim on November 12, 2008 I tried the fix recommended by cuffia on an LPC2138 board and it worked fine. Thanks Cuffia.
