[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [November 2012 Threads] problem with mutexPosted by Prince Chauhan on November 21, 2012 My question is related to semaphores. I am working on STM32VL_DISCOVERY Board, using the ATOLLIC TRUE STUDIO with FRE RTOS. I looked up the mutex semaphore in the API reference, and used them in my program, and compiled it. Got an error complaining about an "undefined reference to xQueueCreateMutex". If I drop in a binary semaphore is compiles just fine. Again, I'm sure I'm just missing something simple. Any ideas?
RE: problem with mutexPosted by Richard on November 21, 2012 Set configUSE_MUTEXES to 1 in FreeRTOSConfig.h.
