I want to use kafkacat command line utility(https://docs.confluent.io/current/app-development/kafkacat-usage.html) on my MacOS Mojave(10.14.5). I executed the below steps

brew install kafkacat

kafkacat -C -b brokerID -t kafkaTopic -e -K '+'

I am getting the error as below

dyld: lazy symbol binding failed: Symbol not found: _timespec_get
Referenced from: /usr/local/opt/librdkafka/lib/librdkafka.1.dylib
Expected in: /usr/lib/libSystem.B.dylib

dyld: Symbol not found: _timespec_get Referenced from: /usr/local/opt/librdkafka/lib/librdkafka.1.dylib Expected in: /usr/lib/libSystem.B.dylib

Abort trap: 6

I've tried uninstalling and reinstalling kafkacat.

I ran into the same issue. Looks like it is coming from librdkafka: https://github.com/edenhill/librdkafka/pull/2569 and the last version of Xcode (11). You can either:

  • Uninstall librdkafka / kafkacat brew version (brew uninstall ...). Rebuild librdkafka using the "fixed" branch and then rebuild kafkacat (method I tested) OR
  • Downgrade Xcode to 10.x

I was experiencing same error with librdkafka in macOS Mojave ver. 10.14.6, I had installed Xcode 11.x.

dyld: lazy symbol binding failed: Symbol not found: _timespec_get

I found an open issue in Blizzard/node-rdkafka describing the same error. As suggested, I downgraded Xcode from 11.x to 10.3, then rebuild librdkafka

brew install --build-from-source librdkafka

It worked!

By the way, it looks like the fix for librdkafka has just been merged into master.

The below worked for me after I read about the issue in https://github.com/edenhill/librdkafka/pull/2569

I uninstalled kafkacat and then librdkafka

brew uninstall kafkacat brew uninstall librdkafka

Then I installed the latest version of kibrdkafka that has the fix but is not available in brew yet like below

brew install librdkafka --HEAD

Then installed kafkacat again

brew install kafkacat

Now the errors are gone and the consumer is connected. Note my XCode version is 11.2.1

brew uninstall librdkafka
brew uninstall kafkacat

Apart from downgrading Xcode from 11.x to 10.3, installing Command Line Tools for Xcode 10.3 was also required. https://developer.apple.com/download/more/

brew install --build-from-source librdkafka
brew install kafkacat
