Have you ever seen this error before? Thanks!

I know that I've encountered strange compile issues when the storage space was running low, maybe you can try to clear some disk space. It sometimes behaves very strangely at compiling. Will try to reproduce it myself.

Thanks for the reply! I endup using this scripts to compile opencv 4.1.1. Just want to check is there any specific reason you're using the opencv from https://github.com/YashasSamaga/opencv/tree/cuda4dnn-csl-low ?

I was playing around with OpenCV and CUDA/cuDNN functionalities, it is not needed anymore. I removed it from the Dockerfile and README.
