Unsupported gpu architecture 'compute_87'

[drvrh]

Hello, I ran command $./build_opencv.sh on my Jetson Nano, but I get error:

[ 28%] Building NVCC (Device) object modules/core/CMakeFiles/cuda_compile_1.dir/src/cuda/cuda_compile_1_generated_gpu_mat.cu.o

What's wrong?

The latest Linux version supporting the Jetson Nano is Jetson Linux 32.7.3: https://developer.nvidia.com/embedded/jetson-linux-archive

The nvcc version included up to Jetson Linux 32.7.3 does not support the Nvidia Ampere GPU Architecture for Orin (compute_87): https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#virtual-architecture-feature-list

The Jetson Nano is based on the Maxwell Architecture (CUDA Architecture Version 5.3)

You can resolve this issue by changing line 110 in build_opencv.sh From
-D CUDA_ARCH_BIN=5.3,6.2,7.2,8.7 To
-D CUDA_ARCH_BIN=5.3
