Hi folks,

Trying to set up a Xymon 4,4 server and I'm getting these errors when it tries to detect the latest RRDtool:

You need the rrdtool and rrdtool development packages. What they're called will depend on which version of Linux you're installing on. I have an old Centos 7 with these packages installed:
rrdtool-devel-1.5.5-1.1.el7.x86_64
rrdtool-1.5.5-1.1.el7.x86_64

Info on the devel package says:

Packager : Japheth Cleaver
URL : http://oss.oetiker.ch/rrdtool/
Summary : RRDtool libraries and header files

If you have Ubuntu or some other OS, you'd be looking for something different.

It would help to know what Linux distribution and version you have installed and what version of rrdtool package (including the development package). I have a current Rocky Linux 9.4 installation that compiled and is running Xymon 4.4.0-alpha1 using rrdtool 1.7.2.

# rpm -qa | grep rrdtool
rrdtool-1.7.2-21.el9.x86_64
rrdtool-perl-1.7.2-21.el9.x86_64

No distribution, it's Linux from scratch. RRDtool version is the latest version, 1.9.0.

If 1.7.2 works, I can downgrade to that.

I've had a bunch of these errors after updating my Gentoo setup to use 
gcc 14.

The issue here isn't rrd, but the test that is used in xymon to detect 
the presence of rrdtool's installation.

The file itself is in the build folder, test-rrd.c

As it does look like you have rrd installed, you could replace the int 
main to simply return 0.

Changing

char* rrdargs

to

const char* rrdargs

also seems to work.


The next stumbling block looks like more of those errors in a few files.

I've naively added a (const char **) besides all parameters that 
complain in the error, but I have no idea whatsoever if it is a good 
fix. But it does compile.

I've attached the patch, not tested beyond "it compiles."
