[QUESTION] Undefined constant `Junges\Kafka\RD_KAFKA_PARTITION_UA`

[mateusjunges]

@irfanpathanudr this constant comes from librdkafka, not this package. You need to install this library in order to use laravel-kafka. This is the installation guide

[irfanpathanudr]

My PHP Version 8.0.12

run commond

composer require mateusjunges/laravel-kafka

but composer show error

• mateusjunges/laravel-kafka[v1.4.0, ..., v1.4.4] require ext-rdkafka ^5.0|^4.0 -> it is missing from your system. Install or enable PHP's rdkafka extension.
  • Root composer.json requires mateusjunges/laravel-kafka ^1.4 -> satisfiable by mateusjunges/laravel-kafka[v1.4.0, ..., v1.4.4].

run commond with

composer require mateusjunges/laravel-kafka --ignore-platform-reqs

no error come but kafka client throw error

Undefined constant "Junges\Kafka\RD_KAFKA_PARTITION_UA"

@mateusjunges Can you pl. help me to come out of this issue? It'll huge thanks for you :)

[rtuin]

@irfanpathanudr This phpinfo() shows the web configuration for PHP. Some installations have a different configuration on CLI. Does rdkafka show up when you run php -i on the terminal, and which version? You can also checked if the rdkafka extension is enabled in terminal at all by running php -m

[irfanpathanudr]

thank you @rtuin

Error :Call to undefined method RdKafka\ProducerTopic::producev()

php -i

Undefined constant "Junges\Kafka\RD_KAFKA_PARTITION_UA" can you plz help out form this issue

[mateusjunges]

@irfanpathanudr The Call to undefined method RdKafka\ProducerTopic::producev() issue occured because the librdkafka version is under 0.11.4, if you upgrade it should work.

[irfanpathanudr]

@mateusjunges my requirement is to setup Kafka client and my system configuration is Ubuntu 18.04 php 7.2, laravel/framework: "^6.2" for Admin, laravel/lumen-framework": "^7.0" for API, Rdkafka 5.0 , librdkafka 0.11.3.

ubuntu 18.4 have only supporte librdkafka 0.11.3 version mention in bellow image or link.

https://repology.org/project/librdkafka/versions http://213.146.141.13/upstreamproject/details/librdkafka

so please help me out to communicate with kafka

[mateusjunges]

@irfanpathanudr It will not work on php 7.2, the minimun php version required is 8.0. About the librdkafka version, i can add a workaround to use the produce method instead, if the version is under 0.11.4, but it will not be able to add message headers.

[rtuin]

I suggest you do not run composer require with the --ignore-platform-reqs flag. The platform requirements defined in laravel-kafka's composer.json is meant to prevent the issues you are running into. This applies to most if not all packages.

[mateusjunges]

@irfanpathanudr i've added support for librdkafka v0.11.3, but as @rtuin mentioned, you should not run composer with --ignore-platform-reqs flag. You are only running into issues because of that, and i can't support you if your system does not follow the minimun requirements needed to use this package. I closed this with #43, but feel free to reopen or create another issue after you fix your system with the minimun requirements of this package.

EDIT: Fixed it by using php-fpm

local.ERROR: Undefined constant "Junges\Kafka\RD_KAFKA_PARTITION_UA" {"exception":"[object] (Error(code: 0): Undefined constant \"Junges\Kafka\RD_KAFKA_PARTITION_UA\" at /var/www/html/smartplement-asset/vendor/mateusjunges/laravel-kafka/src/AbstractMessage.php:9)

Hi, im getting the same error while on Ubuntu 18.4 using build 1.6.6

EDIT: upgrade rdkafka to 6.0.1 still the same

upraded to ubuntu 20.4, still the same

EDIT: Fixed it by using php-fpm

You need to restart apache (If you are using Octane reload and update)
