Bulid opencv4 on Jetson Xavier nx but failed - opencv

Question

I'm trying to implentment openpilot on Jetson Xavier nx. So I'm following https://github.com/eFiniLan/xnxpilot instruction to install dependence.
But when I'm installing opencv4, I get the following errors in ".../opencv/build/CMakeFiles/CMakeError.log"
CMakeFiles/cmTC_ee78d.dir/CheckIncludeFile.c.o -c /home/tshu/opencv/build/CMakeFiles/CMakeTmp/CheckIncludeFile.c

The version of opencv I tried to install is opencv-4.5.2
Can someone give me some advices? Thank you.

Answer 1

Jetpack comes with opencv preinstalled. JetPack 4.4 includes OpenCV 4.1.1. JetPack 4.6 includes OpenCV 4.1.1.
Let me look at the link you sent and I get back to you. You may need to install and compile OpenCV 4.5.2 from source. I wrote some instructions a while a go.

Answer 2

What Jetpack version are you using? OPENCV 4.4, is CUDA GPU accelerated. Using version 4.4 or higher to fully use the Super Resolution function provided by OpenCV. If you are using Jetpack 4.4, you will need to delete the OpenCV 4.1.1 version of JetPack 4.4 and install 4.4 newly.

If you are using NX -D CUDA_ARCH_BIN="7.2"
Run following script with on path:
