Failled at compiling OpenCV 4.0 - 99%
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/tu... I followed everytime except the make command, which I used "make" instead of make -j7. I also allocated swap space on my device.
it seems to me, you ran out of disc space, could you check ?
cmake -DENABLE_PRECOMMPILED_HEADERS=OFFwould make it use much less (trading in disc space for compile time)@geohd . This is wrong link you're posting. The link is for merely pc only not ARM. Your board conatined quad-core meaning from one to four. So you used make -j4( or from 1 to 4) not -j7. The allocated swap must be 2048. I used both links from pyimsearch and learnopencv. What is your OS system are you using...linux, android, IoT, ubuntu, etc. I used rapsberry pi 3B/3B+, using linux.
@berak I'm definately not running out of disk space, I am compiling on a 64GB SD Card. Heres my df after reaching 99% and crashing. (last entry in df) http://prntscr.com/mgpu99
@supra56 I tried following many different tutorials, including this one specifically for my board. https://www.96boards.org/blog/part-2-... Note that I used OpenCV 4.0.1 instead of the old version. I have 1024 swap memory, and it seems to work fine using "make" and not "make -j4". If I run make -j4, i run out of memory, so I just leave it at one thread. I don't know how to increase swap, I just followed that tutorial linked above. I also tried the link at pyimsearch, all to crash at 99% or 100% with the same file crashing. I'm using Debian Buster, the latest release for my board.
please do not post answerd here, if you have a question or a comment, thank you
