NCSDK API-only install on Raspberry Pi fails

I was installing the NCSDK API-only version after looking at https://movidius.github.io/blog/ncs-apps-on-rpi/ and when I try these commands:

 

sudo apt-get install -y libusb-1.0-0-dev cd ~/workspace/ncsdk/api/src make <=== fails here sudo make install

 

I get the below:

My Raspberry Pi info:

 

Linux raspberrypi 4.14.79+ #1159 Sun Nov 4 17:28:08 GMT 2018 armv6l GNU/Linux

Is arm6l not supported anymore? The plan is to use the Intel Movidius Stick on it.

 

Any tips will be helpful. I also found a no. of small doc. issues across your site and the above link as well.

Hi @neomatrix369

 

The guide lists a Raspberry Pi 3 Model B as a prerequisite, which Raspberry Pi model do you have?

 

Also, have you install all the dependencies?

 

sudo apt-get install -y libusb-1.0-0-dev libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler libatlas-base-dev git automake byacc lsb-release cmake libgflags-dev libgoogle-glog-dev liblmdb-dev swig3.0 graphviz libxslt-dev libxml2-dev gfortran python3-dev python-pip python3-pip python3-setuptools python3-markdown python3-pillow python3-yaml python3-pygraphviz python3-h5py python3-nose python3-lxml python3-matplotlib python3-numpy python3-protobuf python3-dateutil python3-skimage python3-scipy python3-six python3-networkx python3-tk

 

Regards,
