OpenCV installation stuck in [99%] Built-in target opencv_perf_stitching without errors

Question

So, I am installing the latest version of OpenCV 3.2.0, and it just got stuck 99% (although I passed nproc to -j because it took so long and the output of nproc was 24), and I wonder if there is a solution that I prefer not to stop. I am not getting any errors:

CUDA 8 Python 3.4.3 OpenCV3.2.0 Ubuntu 14.04

Answer 1

well, it turns out he’s stuck for a long time, and then successfully moves forward. Do not stop the installation. BE A PATIENT !

Answer 2

I have the same problem. The make -j4 caused the creation process to be stuck 99%. Unlike other more successful users, despite waiting several hours and despite having 7.5 GB of swap memory, my process was not resolved.

However, the work was a sentence that I found on this webpage that was trying to build with one core:

 make -j1 

It took longer, but worked.

Answer 3

You must increase your swap.

My setup got stuck too, until I increased my swap. Then it ended. You can try temporarily doing this to see if it helps.

Answer 4

running the command as a fixed sudo problem for me
