Do you wish to remove temporary build files in /tmp/build_opencv ?
(Doing so may make running tests on the build later impossible)

I assume you have not changed the default CMake flags if you face this error. The problem causing nvcc fatal : Unsupported gpu architecture 'compute_87' stems from CUDA_ARCH_BIN=5.3,6.2,7.2,8.7 flag. Try removing 8.7 and run it again.

[tasosman]

Thank you is working fine now

how to remove it

how to remove it

just remove the ,8.7 part. That means the line should be CUDA_ARCH_BIN=5.3,6.2,7.2

thank you i had fixxed that with what are you wrote
