System information (version)
4.5.2Detailed description
following this post to install How to install OpenCV 4.5.2 with CUDA 11.2 and CUDNN 8.2 in Ubuntu 20.04
Steps to reproduce
Followed all the instructions
First of all install update and upgrade your system:
Then, install required libraries:
Generic tools:
Image I/O libs
Video/Audio Libs - FFMPEG, GSTREAMER, x264 and so on.
OpenCore - Adaptive Multi Rate Narrow Band (AMRNB) and Wide Band (AMRWB) speech codec
Cameras programming interface libs
GTK lib for the graphical user functionalites coming from OpenCV highghui module
Python libraries for python3:
Parallelism library C++ for CPU
Optimization libraries for OpenCV
Optional libraries:
We will now proceed with the installation (see the Qt flag that is disabled to do not have conflicts with Qt5.0).
on running
cmakei get this errorCmakeError.log
What is going wrong?
