Unable to open shared library libnvds_kafka_proto.so

Accelerated Computing Intelligent Video Analytics DeepStream SDK

When I compile libnvds_kafka_proto.so from the source, the resulting shared library cannot be opened.

The error message is:

/opt/nvidia/deepstream/deepstream/lib/libnvds_kafka_proto.so: undefined symbol: _ZTVN10__cxxabiv120__si_class_type_infoE
unable to open shared library

Hardware Platform: GPU, x86_64
DeepStream Version: 5.1-21.02
NVIDIA GPU Driver Version: 460.39

Reproduction steps:

# Run Deepstream container on x86_64.
$ docker run --gpus all -it --rm --network host -e CUDA_VER=11.1 nvcr.io/nvidia/deepstream:5.1-21.02-devel

# test_kafka_proto_sync works correctly before I attempt to rebuild libnvds_kafka_proto.so
$ cd /opt/nvidia/deepstream/deepstream/sources/libs/kafka_protocol_adaptor
$ make -f Makefile.test
$ ./test_kafka_proto_sync
Refer to nvds log file for log output

$ make

run with
./test_kafka_proto_sync /kafka protocl adapter library path/

Thank you for your response. Unfortunately I get the same error.

./test_kafka_proto_sync /opt/nvidia/deepstream/deepstream/lib/libnvds_kafka_proto.so
Refer to nvds log file for log output
/opt/nvidia/deepstream/deepstream/lib/libnvds_kafka_proto.so: undefined symbol: 
_ZTVN10__cxxabiv120__si_class_type_infoE
unable to open shared library

In any case, I was able to successfully build a custom implementation of the message broker interface using Rust, so I do not need this to work for my use case. It may be something that you wish to investigate for others.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

What rust is? the customization is still using kafka protocl or your own?

I encountered the same issue. The Makefile contains some errors, see the difference here:
