Problems compiling the collectord -> Warnung: undefinierter Verweis auf mysqlpp

[ans-1984]

Hi,

I'm trying to compile the Collector on a RHEL 8 system, but I run into an error:

Unfortunately, I'm not a programmer, so I don't have that much experience.

The mysql++ and mysql++-devel packages are installed:

root@monitoring /opt/ems-collector/collector # dnf list installed | grep mysql

mysql++-devel.x86_64 3.1.0-12.el7 @System

Would be nice if I could somehow get the collector to work. I would be grateful for any help!

For the last few years I had it running on a Centos 7 system - there I was able to compile it without any problems ... But in the meantime the old server was getting on in years and so I installed a more up-to-date operating system.

Best regards,
Andreas

Hi, everyone,

my request has been dealt with. It doesn't make sense for me to put in any further troubleshooting time ...

I will switch to the ESP32 project.
There everything runs on a small ESP board, which I can then query with Icinga (API).

If anyone is interested in the completely ready-to-use Pollin AVR IO Board, just let me know by email ...

Best regards,
Andreas
