After spending 7+ hours compiling openCV for the dragonboard 410c, it fails at 99%. I already tried many times with much less success.
Here are the last few lines of the stack log:

Here is the cmake command I used:
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D `OPENCV_EXTRA_MODULES_PATH=/media/linaro/WHITEHORSE/opencv_contrib/modules -D PYTHON3_EXECUTABLE=~/.virtualenvs/cv/bin/python3 -D PYTHON_LIBRARY=/usr/lib/aarch64-linux-gnu/libpython3.7m.so -D PYTHON_INCLUDE_DIR=/usr/include/python3.7m -D PYTHON_INCLUDE_DIR2=/usr/include/aarch64-linux-gnu/python3.7m ..`
Here is the tutorial I followed: https://docs.opencv.org/3.4/d7/d9f/tutorial_linux_install.html I followed everytime except the make command, which I used "make" instead of make -j7. I also allocated swap space on my device.
