Detailed description

I am working on Raspberry Pi 4 which has python 3.7 installed. As Pi wheels has not added opencv to their list in python3.7, I am forced to build from source. I have followed a couple of tutorials like: https://www.pyimagesearch.com/2017/09/04/raspbian-stretch-install-opencv-3-python-on-your-raspberry-pi/ or https://www.deciphertechnic.com/install-opencv-python-on-raspberry-pi/ but no matter what I do, I get this error:

/usr/bin/ld: ../../lib/libopencv_core.so.4.1.1: undefined reference to '__atomic_fetch_add_8' /usr/bin/ld: ../../lib/libopencv_core.so.4.1.1: undefined reference to '__atomic_fetch_sub_8' /usr/bin/ld: ../../lib/libopencv_core.so.4.1.1: undefined reference to '__atomic_store_8' /usr/bin/ld: ../../lib/libopencv_core.so.4.1.1: undefined reference to '__atomic_load_8' /usr/bin/ld: ../../lib/libopencv_core.so.4.1.1: undefined reference to '__atomic_compare_exchange_8' collect2: error: ld returned 1 exit status make[2]: *** [modules/core/CMakeFiles/opencv_test_core.dir/build.make:571 : bin/opencv_test_core] Error 1 make[1]: *** [CMakeFiles/Makefile2:2678: modules/core/CMakeFiles/opencv_test_core.dir/all] Error 2 make: *** [Makefile:163: all] Error 2
