[hobbit] undefined reference to `clock_gettime'

Answering my own question here. On all of my systems - and all of a friend's systems, all running RHEL 5.3 - the

LIBRTDEF = -lrt

Makefile workaround does not work.

What DOES work is this:

[root at challenger xymon-4.2.3]# LIBRTDEF=-lrt [root at challenger xymon-4.2.3]# export LIBRTDEF

then make, etc.

I'm trying to install 4.2.3 to a RHEL5.3 system. make returns the following:

../lib/hobbitclient.a(timefunc-client.o): In function gettimer': /usr/src/xymon-4.2.3/lib/timefunc.c:55: undefined reference to clock_gettime' ../lib/hobbitclient.a(timefunc-client.o): In function getntimer': /usr/src/xymon-4.2.3/lib/timefunc.c:67: undefined reference to clock_gettime' collect2: ld returned 1 exit status

I've seen a couple of posts that suggest I add

LIBRTDEF = -lrt

to the Makefile. I've done that, and it gets worse...

Pointers in the right direction appreciated.
