OpennVino and Intel Realsense collaboration work Ubuntu 18.04.

[Alexiif]

I can't compile Intel Realsense with oppenvino support. All version contain some errors.

I got this errors  on openvino 2019.3.334 and realsense 2.37.

I got errors on versions openvino 2021.4 and librealsense-2.45, and any other combinations. I want to know that combinations of versions of openvino and librealsense compile without errors on Ubuntu 18.04.

Hi, just FYI
It seems librealsense-2.4x openvino support still uses IE APIs removed in 2021.x.
You can find a pull request to support 2021.x at https://github.com/IntelRealSense/librealsense/pull/9273 .

librealsense-2.45.0 can be compiled with openvino 2020.3.2 LTS on utuntu 18.04 and gcc 7.5.0 to modify the followings in
librealsense-2.45.0/tools/realsense-viewer/openvino-face-detection.cpp :
40c40
< void detected_face::update_age( float value )
---
> void update_age( float value )
45c45
< void detected_face::update_gender( float value )
---
> void update_gender( float value )
207c207
< rs2::depth_frame df = NULL;
---
> rs2::depth_frame df = rs2::frame{};

These can avoid the errors.
