OpenCV installation Raspberry Pi 3B model

Question

I am trying to install OpenCV in raspberry pi 3B but every time I try to install it gives error during compilation. I have been trying this for a long time and I don't know how to do it. I have followed mainly all the instruction given in these articles:

• Install opencv 4 on raspberry pi
• Install guide raspberry pi 3 raspbian jessie opencv 3

Answer 1

I had the same error a few weeks ago and for me it works when I just use

make -j

instead of

make -j4

-j4 simply means that the raspberry pi uses all for cpu cores instead of just one with make -j

Hope I could help and please write if that works for you as well;)
