Incompatibility with Zabbix 4.0

Hi,
It looks like this is not compatible with Zabbix 4.0:

Recompilation should solve the problem. Looks like you are upgrading from Zabbix 3.0 or lower. If you prefer precompiled packages simply grab the one for 3.2+ and you will be fine.

That zabbix-agent was the 3.4 version. Then I upgraded it to 4.0 and started to get that error.

I'm afraid this cannot be true. Log message

unsupported module "libzbxpgsql.so" version: 1

shows that your module wants to use API version 1 which was in use up to Zabbix 3.0, since version 3.2 Zabbix expects modules to use API version 2.

Therefore if module works with 3.2 or 3.4 it should also work with 4.0, at least it shouldn't yield such an error.

So, I am already using the 3.2+ version.

I'm using Zabbix Server 4.0 and getting this error:

Ouch. After upgrading agent this problem is solved for me.

[cavaliercoder]

I'd like to keep this open in case I get a chance to publish v4 packages.

Also worth noting that Zabbix have had issues with breaking changes to the module API between agent versions. In other words, the 3.2 module may not work with 3.4+.

Does the problem continue for zabbix-release-4.0-1.el7.noarch zabbix-agent-4.0.3-1.el7.x86_64
zabbix-sender-4.0.3-1.el7.x86_64 zabbix-get-4.0.3-1.el7.x86_64 ?

Hi,

Could you tell me more about how we can help ? What need to be changed to works with the version 4 of zabbix ? I know the api has changed but don't know the difference between the version one and two. I will check the documentation and try to find a way to give some help.

Best regards,
L.

After quickly reading the documentation, if we (re)compile this module with the latest stable of zabbix 4, it should work. Do you know if someone did it before ? and if it works ?

Best regards,
