Hi, Recently I try to run my project in qt5.6.1 with OPENVINO, but have received this error: "symbol lookup error: /opt/intel/openvino_2020.3.194/deployment_tools/inference_engine/lib/intel64/libinference_engine.so: undefined symbol: _ZN3tbb8internal13numa_topology4fillEPi" This is my develop enviroment: Ubuntu 18.04 Qt5.6.1 OpenVINO2020.3 This is .pro file in my project:

Could anyone give some advise? Thx a lot.

@Ludwig-Zh looks like you have different version of TBB on your system and Inference Engine tries to use it, while Inference Engine needs custom version of TBB which is distributed in OpenVINO package. Please, make sure that correct version of TBB is used.

Yes,I confirm this problem.QT use libtbb.so.2 in usr/lib/x86_64-linux-gnu/ rather than openVINO version.when I run my project in terminal with environment setup correctly,it works well. But I don't know how to deal with this issue when debugging in QT?Need more help yet.

Thanks @ilya-lavrenov

What is the issue with debugging?

Ludwig-Zh commented 4 years ago

What is the issue with debugging? I guess the issue is how to set the openVINO environment for QT? Because "#source /opt/intel/openvino/bin/setupvars.sh" in .bashrc only work for terminal.

Ludwig-Zh commented 4 years ago

I have solved this issue, share here: In Qt start script "qtcreator.sh", add a line "source /opt/intel/openvino/bin/setupvars.sh", then we can debug by Qt IDE with openVINO enviroments. Note: must change the first line in qtcreator.sh( "#! /bin/sh"==>"#! /bin/bash"), couse th e SOURECE command only work in bash.
