Hello, I am trying to build OpenCV 4.8.1 on Linux 22.04 on Nvidia 4070 card. The machine has Xeon processor. While enabling CUDA==On, I get the following errors: /home/csverma/Downloads/opencv-4.8.1/modules/core/include/opencv2/core/hal/intrin\_sse.hpp:1439:1: note: in expansion of macro ‘OPENCV\_HAL\_IMPL\_SSE\_SHIFT\_OP’ 1439 | OPENCV\_HAL\_IMPL\_SSE\_SHIFT\_OP(v\_uint64x2, v\_int64x2, epi64, v\_srai\_epi64) | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~ /home/csverma/Downloads/opencv\_contrib/modules/xphoto/src/grayworld\_white\_balance.cpp:332:26: note: candidate expects 1 argument, 2 provided 332 | v\_sR1 = v\_shr(v\_mul(v\_sR1, v\_gainR), 16); | ~~~^~~~~~~~~~~~~~~~~~~~~~~~~ /home/csverma/Downloads/opencv\_contrib/modules/xphoto/src/grayworld\_white\_balance.cpp:333:26: error: no matching function for call to ‘v\_shr(cv::hal\_baseline::simd128\_cpp::v\_uint32, int)’ 333 | v\_sR2 = v\_shr(v\_mul(v\_sR2, v\_gainR), 16); | ~~~^~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /home/csverma/Downloads/opencv-4.8.1/modules/core/include/opencv2/core/hal/intrin.hpp:217, ---
