I wanted to use counting semaphores in a RX62 FreeRtos Project, GnuRX toolchain,
the iead was to use
xSemaphoreGiveFromISR( xSci_Semaphore, &xHigherPriorityTaskWoken ); inside the
SCI rx interrupt to detect comands on the serial port

i declare the

static xSemaphoreHandle xSci_Semaphore = NULL; //pot ser counting o Binary
when i call the function

xSci_Semaphore=xSemaphoreCreateCounting( 10,0);//fins a rebre 10 salts de linia
no pot quedar-se pillat

I get

Phase Compiler finished
Phase Linker starting

C:\WorkSpace\Mine_RTOS_702\Mine_RTOS_702\Debug\main_.o: In function `GPS':

C:\WorkSpace\Mine_RTOS_702\Mine_RTOS_702/main_.c:194: undefined reference to
`xQueueCreateCountingSemaphore'

Phase Linker finished

Build Finished

1 Error, 0 Warnings

in FreeRTOSConfig.h i have defined

#define configUSE_MUTEXES 1
#define ConfigUSE_COUNTING_SEMAPHORES 1

and i have included this in main_.c

/* FreeRTOS.org includes. */
/* Kernel includes. */
#include "FreeRTOS.h"
#include "task.h"
#include "semphr.h"
#include "queue.h"

Before i just used a binarySemaphore just fine in the same project, even if
i try to use it in the reference project i get the same error.
In the book, the example 12 uses thet function just fine on the Renesas compiler
hew project

Thank you very much for reading and any help or hints

Is this cut from your source or a mistype in your post? "Config" must be
"config"
