Nagios Support Forum

No I haven't seen anything in the logs.
But I am willing to try your solution on my return.

What mod_gearman version did you use and does in stall the gearmand deamon also?

I am using mod_gearman 3.0.5 as "base" before patching with the Nagios 4.3.4 headers (there were also a Nagios-header change between 4.3.2 and 4.3.4).
gearmand is version 0.33 (from labs.consol.de).

@delboy1966, let us know if you have any more questions/issues.

Trying to recompile mod_gearman using the headers from Nagios 4.
I get

configure: error: Compiling Mod-Gearman requires ltdl.h

Any ideas?

Do you have installed "libtool-ltdl-devel"?

According to the .spec-file the following packages are needed to build mod_gearman:

BuildRequires: autoconf, automake, ncurses-devel
BuildRequires: libtool, libtool-ltdl-devel, libevent-devel
BuildRequires: gearmand-devel

No I didn't have it installed.

Installed that and other required packages and now get an error on make

# make
make all-am

Did you re-run ./configure ...?
And are you sure gearmand-devel is installed (gearmand-devel installs /usr/include/libgearman-1.0/limits.h which contains "#define GEARMAN_MAX_UNIQUE_SIZE 64")?

That was already installed:

# rpm -qa | grep gearmand-devel
gearmand-devel-0.25-1.x86_64

# ls -l /usr/include/libgearman-1.0

It doesn't have that file in the directory.
If I try to do a yum update on it there is no updated package available.

I am using:
$ rpm -qa | grep gearmand
gearmand-0.33-6.x86_64
gearmand-server-0.33-6.x86_64
gearmand-devel-0.33-6.x86_64

All from labs.consol.de (https://labs.consol.de/repo/stable/rhel7/x86_64/)
You probably have to change the "rhel7" to your distro/release.

I now have it all installed

A bit unsure about the nagios.cfg line as I can't find anything in the docs about that.
The install doesn't seem to have moved the modules from neb_module_nagios4:

mod_gearman.o
result_thread.o

Do I have to move them somewhere?
