resource_monitor: Compile error in OSX 10.14

[rkkautsar]

From the manpage:

It has been tested in Linux, FreeBSD, and Darwin

But it's not packaged in the stable version for Darwin. So I tried to compile it manually:

cctools-7.0.11-source/resource_monitor/src
➜ make
COMPILE rmonitor_helper.o
rmonitor_helper.c:380:49: error: use of undeclared identifier 'AF_NETLINK'

make: *** [rmonitor_helper.o] Error 1

make-ing the whole cctools executes successfully but resource_monitor is not generated. This is different from when I tried to compile it in Linux. Is this intended?

@rkkautsar, thank you for your report. Yes this is expected, as the resource monitor is no supported in Darwin, as it will not really measure anything useful. It is a documentation bug...
