zabbix-agent for EL-9 dependency problem

[solarflow99]

I am surprised to see zabbix-agent doesn't install, seems its expecting the wrong libraries?

Problem: conflicting requests
- nothing provides liblber.so.2()(64bit) needed by zabbix-agent-6.2.6-release1.el9.x86_64
- nothing provides liblber.so.2(OPENLDAP_2.200)(64bit) needed by zabbix-agent-6.2.6-release1.el9.x86_64
- nothing provides libldap.so.2()(64bit) needed by zabbix-agent-6.2.6-release1.el9.x86_64
- nothing provides libldap.so.2(OPENLDAP_2.200)(64bit) needed by zabbix-agent-6.2.6-release1.el9.x86_64

Shouldn't it be looking for libldap-2.4.so.2 instead?

$ find / -name libldap*.so.2
/usr/lib64/libldap_r-2.4.so.2
/usr/lib64/libldap-2.4.so.2​

$ find / -name liblber*.so.2
/usr/lib64/liblber-2.4.so.2​

This was for RHEL/Centos 9. Is anyone using this yet?

[ArnoAnderson]

It works here, but I use the 6.0.4 version.

Does your system have liblber.so.2 or libldap.so.2 installed anywhere? If so, can you type: rpm -qif path-to-file

Not necessarily. It's looking for the shared object name (SONAME) of a library it was linked with, though the output above is an altered version of that, generated by rpmbuild's dependency finder and encoded with some additional glop (like the '(64bit)') for RPM's dependency mechanism.

$ find / -name libldap*.so.2
/usr/lib64/libldap_r-2.4.so.2
/usr/lib64/libldap-2.4.so.2​

$ find / -name liblber*.so.2
/usr/lib64/liblber-2.4.so.2​

The file name on disk doesn't need to match the required SONAME, as long as there's a way for the loader to find the right shared object that provides that SONAME.

You can use "readelf -d /path/to/shared/library" and then look for the SONAME to find the actual shared object name for the library. It might be the same as the filename, but very often it's different.

To find what package provides the RPM-encoded libraries output in the error message, you want to use something like

$ sudo yum whatprovides 'libldap.so.2(OPENLDAP_2.200)(64bit)'

When searching for a library like that, be sure you copy the full bit from the error message and quote it so the shell doesn't eat any of the parens.

I was actually aware openldap provides these libraries, it was that one file in particular I wanted to identify which package supplied it since it worked for ArnoAnderson. But I see from your output opendlap 2.6 caught my attention, that was the hint. I was on RHEL 9.0 and I needed to be on 9.1 since that uses opendlap 2.6. And it did the trick.

$ rpm -qf /usr/lib64/libldap.so.2
openldap-2.6.2-3.el9.x86_64​

Thanks to all those who replied.
