Unity 2019.3.3 NuGet for Unity librdkafka.dll failed to load

[0x6c6565]

I'm trying to use NuGet For Unity to set up Kafka in Unity 2019.3.3 on Windows 10. Everything comes into the project fine, but...

When I test:

string hostAndPort; // Set to a valid Kafka host:port

ProducerConfig config = new ProducerConfig() { BootstrapServers = hostAndPort }; ProducerBuilder<Null, string> builder = new ProducerBuilder<Null, string>(config);

// FAILED TO LOAD librdkafka.dll // builder.Build(); // FAILED TO LOAD librdkafka.dll //

========= Environment:

• Windows 10
• Unity 2019.3.3
• Player settings (tried with Allow Unsafe Code and without it)
• NuGet for Unity imports:
  • Kafka.1.3.0
  • System.Buffer.4.4.0
  • System.Memory.4.5.0
  • System.Numerics.Vectors.4.4.0
  • System.Runtime.CompilerServices.Unsafe.4.5.0

Literally, ANY help is appreciated. I cannot locate a walk through of how to get this set up- only random suggestions and bug complaints.

Thanks,

try using Library.Load, specifying an absolute path to a librdkafka.dll before using any other Confluent.Kafka method (and let us know if it works!).

We don't test with unity, i need to do so and see what's up.

I think it's an issue with NuGet for Unity- which was recommended somewhere in here... I'm not getting the libraries (dlls).

@mhowlett I tried pulling the package (and its dependencies) into VS and then bring them into a Unity project and then calling Library.Load(). I get the following error:

Win32Exception: %1 is not a valid Win32 application.

i've labelled this as enhancement because we'd like to support unity. unfortunately don't have time to investigate atm.
