I have no idea how one builds opencv but it sounds like you might be running out of memory.

Be sure to setup a decent sized swap space.

Be sure to run your build on only one thread. Often make files will try to compilation multiple files in parallel, which takes more memory.

I managed to compile the Qt5 libraries on an early Pi with a swap space that was actually on an NFS mount from my PC. It took all night!

Or, why not make life easy and build opencv on a Pi 4? Then move the executables to the zero.

Code: Select all

sudo apt install libopencv-dev opencv-doc
