Hi, I just installed OpenVINO in Ubuntu 16.04, all the dependencies, successfully run classification_sample_async but when tried to build demo #2, got the following errors:

and many more 'undefined refererences' until:
make: *** [security_barrier_camera_demo] Error 2

I couldn't find a similar problem/solution, ¿can anyone help me?
Thanks and best regards,

Hi Cesar,
It looks like you are running OpenVINO from a Anaconda virtual environment. I have not tried this myself and there may be additional steps required. Could you try installing the OpenVINO toolkit on your system without the virtual environment?

Jesus

Yes, you are right, I'm working inside a conda environment.
I'll try your suggestion and let you know.
Many thanks!

You have to install GTK2 either to the system, either to the conda environment (e.g. this package: https://anaconda.org/conda-forge/gtk2).
