Why do I run out of storage space when downloading OpenCV on my Jetson Nano?"

Hello everyone

I’m using a Jetson Nano with eMMC and was experiencing a lot of slowness issues, so I reinstalled JetPack on the device and it improved the speed. However, I didn’t have OpenCV installed, and I’m following this tutorial:

But when I run the ‘make -j4’ command, it only loads up to 40% and gives me an error, which is:
‘fatal error: can’t write PCH file: No space left on device} // namespace cv’.

I checked my memory, and I’m using 13GB out of 14GB. How can I solve this? It’s really a headache.


Suppose you indicate storage rather than memory.
Please check the below topic to expand the storage amount:
