Dear, could you please give me some advice about how to execute "./ll_cpp_compression_example hardware_path" successfully?

================

./ll_cpp_compression_example software_path

The example will be run on the software path. Content was successfully compressed and decompressed. Compressed size: 20

./ll_cpp_compression_example hardware_path

The example will be run on the hardware path. qpl-diag: Intel QPL version 1.2.0 qpl-diag: loading driver: libaccel-config.so.1 terminate called after throwing an instance of 'std::runtime_error' what(): An error acquired during compression job initializing. Aborted (core dumped)

Hello @happyvera1115, could you please print out the status value at https://github.com/intel/qpl/blob/develop/examples/low-level-api/compression_example.cpp#L60 (as it seems to be the place where exception is happening based on your description)? Also, could you please double check that you have libaccel-config.so.1 available either in standard location or in LD_LIBRARY_PATH?

Thanks mzhukova.. This issue is solved by Oakley yesterday. after having cmd "ldconfig /usr/lib64" in my system, this phenomenon is gone and no core dump error occurred.
