Subject: [Xenomai] rtdm_driver.h fails to build: implicit declaration of smp_mb__before_atomic_dec()
Date: Tue, 19 May 2015 22:54:12 +0200	[thread overview]
Message-ID: <555BA2F4.4030106@techfak.uni-bielefeld.de> (raw)

I'm trying to build Xenomai 2.6.4 on linux 3.18.13 with i-pipe patch for 
3.18.12.
When enabling RTDM support, the compiler throws the following error:

In file included from ../kernel/xenomai/skins/posix/syscall.c:40:0:
../include/xenomai/rtdm/rtdm_driver.h: In function ‘rtdm_context_unlock’:
../include/xenomai/rtdm/rtdm_driver.h:587:2: error: implicit declaration 
of function ‘smp_mb__before_atomic_dec’ 
[-Werror=implicit-function-declaration]
   smp_mb__before_atomic_dec();
   ^
cc1: some warnings being treated as errors

This function became deprecated in kernel 3.16 and was removed in 3.18.

Best, Robert
