Hi at all, I'am sure that the same code run fine with Xenomai-2.1.1, kernel linux-2.6.15-ipipe-1.2-15. Why there are problems now? I want underline my purpose: my tasks should be exit in asyncronous way executing costom exit routine. How can I do this in Xenomai? I've considered the use of rt_add_hook() but compiling the code the compiler returns these errors: warning: implicit declaration of function `rt_task_add_hook' undefined reference to `rt_task_add_hook' collect2: ld returned 1 exit status
Thanks for help!
