I can't by any means get to install OpenCV or Darknet

[Tony]

I'm trying to follow this tutorial here https://www.pyimagesearch.com/2015/07/27/installing-opencv-3-0-for-both-python-2-7-and-python-3-on-your-raspberry-pi-2/ but nothing I do works when I get to install numpy, opencv, or darknet.

 

When I try to build OpenCV following default instructions (or any for that matter) I get:

  It fails with the following output:

don't know what to do and there's nothing online that helps me out.

 

the only thing that worked was apt-get install python-opencv but it installs a very old version which I can't use for my project.

 

Also when I try to make darknet I get:

I'm working on an Orange Pi Zero 256mb ram

Which armbian-image do you use? ( Please give link from armbianmonitor -u )

Did you try a new mainline image? (Newer c++ or gcc version?)

Solved it, I was using Debian Jessie, switched to Ubuntu Xenial and everything worked with no problem. Seems the software Debian Jessie distro uses is too old or incompatible.
