Building (linking?) error with demo_security_barrier.sh

[Martinez__Cesar]

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:

...[building until here:]

and many more lines like that, then lines like:

and many more 'undefined refererences' until:

make: *** [security_barrier_camera_demo] Error 2
Error on or near line 189; exiting with status 1
 

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?

Regards,

Jesus

[Martinez__Cesar]

Yes, you are right, I'm working inside a conda environment.

I'll try your suggestion and let you know.

Many thanks!

[JesusE_Intel]

No problem, please let me know how it goes!

Regards,

Jesus

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