编译OpenCV 4.4的Cuda有时候会nvcc报错

报错内容为"nvcc fatal: A single input file is required for a non-link phase when an outputfile is specified" error

虽然命令里面输入了        -D CUDA_NVCC_FLAGS=”-D_FORCE_INLINES –expt-relaxed-constexpr” \

但其实不起作用，需要修改“opencv/cmake/OpencvDetectCuda.cmake”的cmake文件，然后再cmake，make

将这一行做如下修改。

  set(NVCC_FLAGS_EXTRA ${NVCC_FLAGS_EXTRA} -gencode arch=compute_${CMAKE_MATCH_2},code=sm_${CMAKE_MATCH_1})

to

  set(NVCC_FLAGS_EXTRA ${NVCC_FLAGS_EXTRA} -D_FORCE_INLINES -gencode arch=compute_${CMAKE_MATCH_2},code=sm_${CMAKE_MATCH_1})
