Dear list
When I compile gpsd 3.16 using scons I get a warning
Checking for C header file libkern/OSAtomic.h...
No memory barriers - SHM export and time hinting may not be reliable.
But when I run dpkg -l it reads
ii cpp 4:4.9.2-2 armhf GNU C preprocessor (cpp)
ii cpp-4.9 4.9.2-10 armhf GNU C preprocessor
As far as I understand memory barriers are part of c11. The compiler is
new enough to provide C11 but it's not enabled.
Am I missing something? Or can the warning be ignored?
uname -a gives
Linux piaware 4.4.0-1-rpi2 #1 SMP Debian 4.4.6-1+rpi14 (2016-05-05)
armv7l GNU/Linux
Regards
Robin
