Encountering errors on same step of NCS2 guide for multiple installations

[Matthew_Beck]

Hello,

I proceeded with the correct solution given here: https://community.intel.com/t5/Intel-Distribution-of-OpenVINO/Perfectly-set-up-OpenVino-multiple-times-encountering-same-NCS2/m-p/1564138#M30547 and continued forward with the NCS2 instructions here: https://docs.openvino.ai/archive/2022.2/openvino_docs_install_guides_configurations_for_ncs2.html#ncs-guide-raspbianos and I am encountering errors on the same step for both installations I am working with:

How may I proceed further with the setup? I am very very close to completion Thank you.

Hi Matthew_Beck,

Thanks for reaching out. Can you try to install the dependencies and see if this helps.

sudo apt-get update

sudo apt-get install -y git cmake scons build-essential

Or

sudo apt-get update

sudo apt-get install -y build-essential

Regards,

Aznie

I am sure this issue will eventually be overcome. Thank you.

Hi Matthew_Beck,

On Debian/Ubuntu Linux, gflags can be installed using the following command:

sudo apt-get install libgflags-dev
