compling error in winAVR

Posted by cai zifang on May 5, 2008
I want to use the mutexes,and
#define configUSE_MUTEXES 1 //in FreeRTOSConfig.h
#include "semphr.h" //in FreeRTOSConfig.h
xSemaphoreHandle xSemaphore = NULL ; //in main.c


../queue.h:119: error: expected ';', ',' or ')' before 'uxQueueLength'
../queue.h:455: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueGenericSend'
../queue.h:735: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueGenericReceive'
../queue.h:750: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'uxQueueMessagesWaiting'
../queue.h:1057: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueGenericSendFromISR'
../queue.h:1146: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueReceiveFromISR'
../queue.h:1152: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueIsQueueEmptyFromISR'
../queue.h:1153: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueIsQueueFullFromISR'
../queue.h:1154: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'uxQueueMessagesWaitingFromISR'
../queue.h:1171: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueAltGenericSend'
../queue.h:1172: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueAltGenericReceive'
../queue.h:1187: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueCRSendFromISR'
../queue.h:1188: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueCRReceiveFromISR'
../queue.h:1189: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueCRSend'
../queue.h:1190: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueCRReceive'
../queue.h:1197: error: expected ';', ',' or ')' before 'uxCountValue'
../queue.h:1203: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueTakeMutexRecursive'
../queue.h:1204: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'xQueueGiveMutexRecursive'
make: *** [croutine.o] Error 1

I donot change the queue.h file,why does it have error?
I use the FreeRTOS V5.0.0.

Probably you are including header files in bad order. Do not include semphr from freertosconfig.h but from the C file that uses semaphore. semphr.h must come after FreeRTOS.h. See the demo files that include semphr.h for an example of including in the right place.

woops,Thank you very much . I move #include “semphr.h" to main.c file,and locate it after #include "FreeRTOS.h",then it is ok.
When I locate it before #include "FreeRTOS.h", the same error will occur.Really incredible!I didnot think of it before.
