I’m going to activate the cuda compiler in opencv but when doing a make build I get an error like this “the c compiler identification is unknown”
You want to manually enable CUDA filters and build OpenCV, right?
A user has shared a script:
GitHub - mdegans/nano_build_opencv: Build OpenCV on Nvidia Jetson Nano
Please give it a try.
I got the error “the c compiler identification is unknown”
We have tried the script and it works fine. If you still hit issue, please re-install system image through SDKManager and try again.
I saw some non-Jetson related issues suggesting to post the output of:
Another post suggested that in some cases the files in need of access required root privilege (
sudo), but the
CMakeError.log would probably clarify that. The key seems to be that the compiler must be found, and a simple test program must compile. The error log might give details on why this failed.
