Hobbit / XYMON does not compile on CentOS 5 and complains about clock_gettime issues.

Error: timefunc.c:55: undefined reference to `clock_gettime’

Here is how to fix this issue.
Download Hobbit-4.2.3.tar.gz
#1 make sure pcre-devel is installed (#~yum install pcre-devel)
#2 add xymon user (#useradd xymon)
#3 set varible for “ltr” (#LIBRTDEF=-lrt)
#4 export varible (#export LIBRTDEF)
#5 Configure Hobbit inside hobbit src directory (#./configure –client)
#6 Compile program (#make)
#7 Install program (#make install)
#8 Start hobbit client (#/home/xymon/client/runclient.sh start)

Afterwards your hobbit / xymon client should be running on your CentOS or Fedora core systems.

cc -o ../client/hobbitd_client -Wl,--rpath=/usr/lib64 hobbitd_client.o hobbitd_worker.o hobbitd_buffer.o client_config.o ../lib/hobbitclient.a -L/usr/lib64 -lpcre ../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 make[1]: *** [../client/hobbitd_client] Error 1

`If You get the Following Errors:`

gcc -o ../client/xymond_client -Wl,--rpath,/usr/lib64 xymond_client.o xymond_worker.o xymond_buffer.o client_config.o ../lib/xymonclient.a -L/usr/lib64 -lpcre xymond_worker.o: In function `net_worker_run': /root/xymon-4.3.0/xymond/xymond_worker.c:292: undefined reference to `locator_init' /root/xymon-4.3.0/xymond/xymond_worker.c:298: undefined reference to `locator_register_server' /root/xymon-4.3.0/xymond/xymond_worker.c:312: undefined reference to `locator_serverdown' xymond_worker.o: In function `net_worker_heartbeat': /root/xymon-4.3.0/xymond/xymond_worker.c:80: undefined reference to `locator_serverup' xymond_worker.o: In function `net_worker_run': /root/xymon-4.3.0/xymond/xymond_worker.c:317: undefined reference to `locator_serverdown'

The just Add "locator.o" to CLIENTLIBOBJS in lib/Makefile inside of the XYMON build directory. Then re-run "make" and you should be able to build the client.

Enjoy….

Yes, I know CentOS 5 does not come with a repository that holds valid redhat style rpm’s for rrdtool. So here is how we fix that. We are going to echo to a new file the repo information you will need to allow yum to install rrdtool.

We create a file called dag.repo in /etc/yum.repos.d/ by running the echo cmd below. Just copy and past it in to your putty window and hit [enter] once. Then let’s cat the file to make sure it has saved correctly.

echo "[dag] name=Dag RPM Repository for Red Hat Enterprise Linux baseurl=http://apt.sw.be/redhat/el\$releasever/en/\$basearch/dag gpgcheck=1 gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt enabled=1" > /etc/yum.repos.d/dag.repo

Now run

[root@localhosts]#cat /etc/yum.repos.d/dag.repo
And you will see this
[dag] name=Dag RPM Repository for Red Hat Enterprise Linux baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag gpgcheck=1 gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt enabled=1
Now run
[root@localhosts]# yum install rrdtool

This is also good for

awstats
cacti
bandwidth
cfengine
ClamAV
Claws Mail
darkstat
dante
devilspie
dnstop
dvd95
dvdrip
etherape
flash-plugin
fuse
gkrellm
iperf

Another good place to get rrdtool for cent if you just want to download the RPM’s and go..
RRDTOOL
