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

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.
