Confluent Kafka Go包是否与Ubuntu 22.04兼容?

Does Confluent kafka go package compatible with ubuntu 22.04?

问题

我正在使用confluent kafka包在我的数据流服务器中,使用的是Ubuntu 20.04和Golang。现在我将操作系统更改为Ubuntu 22.04。

现在我遇到了以下错误:

- kafka.producer/producer.go:18:26: undefined: kafka.Producer
- kafka.producer/producer.go:35:17: undefined: kafka.ConfigMap
- kafka.producer/producer.go:40:30: undefined: kafka.NewProducer
- kafka.producer/producer.go:133:50: undefined: kafka.Message
- kafka.producer/producer.go:134:27: undefined: kafka.TopicPartition
- kafka.producer/producer.go:136:23: undefined: kafka.PartitionAny

但是在相同的代码中,segmentio包可以正常工作。问题是我想使用confluent包,因为它具有订阅和取消订阅功能,我认为这是相对于segmentio包的优势。

有人知道如何解决这个错误吗?

英文:

I was using confluent kafka package for my data streaming server in golang using ubuntu 20.04 and now I changed my os to ubuntu 22.04.

Now im getting these errors:

- kafka.producer/producer.go:18:26: undefined: kafka.Producer
- kafka.producer/producer.go:35:17: undefined: kafka.ConfigMap
- kafka.producer/producer.go:40:30: undefined: kafka.NewProducer
- kafka.producer/producer.go:133:50: undefined: kafka.Message
- kafka.producer/producer.go:134:27: undefined: kafka.TopicPartition
- kafka.producer/producer.go:136:23: undefined: kafka.PartitionAny

But the segmentio package is working fine in the same code. The thing is I want to use confluent package because it has subscribe and unsubscribe features, which I felt advantage over the segemntio package.

Does anyone knows how to fix this error?

由于github.com/confluentinc/confluent-kafka-go/v2/kafka包使用了librdkafka C库的绑定,您首先必须确保cgo正确配置。

常见的检查事项包括:

  1. 确保cgo已启用(CGO_ENABLED="1"):

    $ go env CGO_ENABLED
    0
    $ go env -w CGO_ENABLED="1"
    
  2. 确保C编译器可用。运行go env CC查看使用的C编译器。

除了检查cgo,还需要确保librdkafka可用。请参阅构建标签

  • 默认情况下,将使用捆绑的特定平台的静态构建的librdkafka。这在Mac OSX和基于glibc的Linux发行版(如Ubuntu和CentOS)上可以直接使用。
  • 在基于musl的Linux发行版(如Alpine)上构建时,必须指定-tags musl。将使用捆绑的静态musl构建的librdkafka
  • 使用-tags dynamic动态链接librdkafka。必须通过其他方式手动安装共享的librdkafka库(apt-get、yum、从源代码构建等)。
英文:

Since the github.com/confluentinc/confluent-kafka-go/v2/kafka package uses bindings on-top of the librdkafka C library, you have to make sure cgo is configured correctly first.

The common things to check are:

  1. make sure cgo is enabled (CGO_ENABLED="1"):

    $ go env CGO_ENABLED
    0
    $ go env -w CGO_ENABLED="1"
    
  2. make sure the C compiler is available. run go env CC to see which C compiler is used.

Besides checking cgo, it's also necessary to make sure librdkafka is available. See build tags:

> - By default the bundled platform-specific static build of librdkafka will be used. This works out of the box on Mac OSX and glibc-based Linux distros, such as Ubuntu and CentOS.
> - -tags musl - must be specified when building on/for musl-based Linux distros, such as Alpine. Will use the bundled static musl build of librdkafka.
> - -tags dynamic - link librdkafka dynamically. A shared librdkafka library must be installed manually through other means (apt-get, yum, build from source, etc).
