CMake Error: Unknown argument -ENABLE_MQTT=on

[alkomm]

I followed the regular documentation (https://wiki.volkszaehler.org/software/controller/vzlogger/installation_cpp-version) for installing vzlogger, but unfortunately, I'm getting this error immediately when I try to install MQTT:

CMake Error: Unknown argument -ENABLE_MQTT=on
CMake Error: Run 'cmake --help' for all supported options.

my command:

./install.sh vzlogger libjson libsml mqtt

i'm on raspberry pi 4, with ubuntu server.

I can't replicate the failure over here on Raspbian.

Give it a try and run ./install.sh vzlogger. If I'm not confused MQTT will still be included.

[alkomm]

hi @J-A-U im not using raspbian, it is the normal ubuntu 22.04.2 LTS server from the official site.

yes the normal install ./install.sh works great. But im not sure if mqtt will be included.

does this mean its included?

if so, how can i test that vzlogger use mqtt? i already added config in /etc/vzlogger.conf

but its not working.

Edit:

my config looks like this:

          "middleware": "<middleware>",
          "aggmode": "none",
          "duplicates": 0
        },
        {
          "uuid": "<uuid>",
          "identifier": "2.8.0",
          "api": "volkszaehler",
          "middleware": "<middleware>",
          "aggmode": "none",
          "duplicates": 0
        }
      ],
      "protocol": "d0",

      "read_timeout": 10
    }
  ]
}

the middleware is getting data, but mqtt not. (i removed sensitive data)

in the log there is also no 1883 mention. (so no connection try)

[J-A-U]

im not using raspbian,

I got that. Mentioned it to be clear.

it is the normal ubuntu 22.04.2 LTS server from the official site.

Which i can't test here.

does this mean its included?

I think so. You can run the build again. It won't do anything because nothing changed. But in the texts i had clear indication MQTT was included.

but its not working.

That's not a helpful description. Clues from the logfile?

[alkomm]

okay, there is nothing in the logfile, but i checked now with the mqtt explorer, if something comes in mqtt. the last data is in there.

Perfect! thank you! it was actually the normal ./install.sh after restart it worked for me.
