If this is info is not a typo,, it seems you are mixing recent master with old contrib branch.
If I understand correctly, that's not supported, and that will be the cause of this build failure.
Is this information precise ? Is there any particular reason you wish to mix old contrib and recent master ?

[LaurentBerger]

I don't think so https://github.com/LaurentBerger/opencv_contrib even with master and
https://github.com/LaurentBerger/opencv Merge pull request opencv#19078 from zihaomu:dasiamrpn_tracker_c_plus…13a1105 16 hours ago

I don't know why Version control (extra): 4.1.1-495-g0b8aecd9e is

in opencv_contrib git log gives me :

    disable NVIDIA Optical Flow SDK when CUDA < 10.0
      * follow the review comment
      * add missing constructors when not covered
      * add definition in cu file

[tomoaki0705]

I don't know why Version control (extra): 4.1.1-495-g0b8aecd9e is

Right. My bad. Nothing wrong on this point.

Any chance you have a copy of cmake output that contains such message below ?

opencv_contrib/modules/cudaoptflow/CMakeLists.txt

Line 26 in 0b8aecd

message(STATUS "Building with NVIDIA Optical Flow API 2.0")

What I see is that the error message indicates that this is a linker error

1>nvidiaOpticalFlow.obj : error LNK2019: unresolved external symbol "void __cdecl cv::cuda::device::optflow_nvidia::FlowUpsample(void *,unsigned int,unsigned int,unsigned int,void *,unsigned int,unsigned int,unsigned int,unsigned int)" (?FlowUpsample@optflow_nvidia@device@cuda@cv@@YAXPEAXIII0IIII@Z) referenced in function "public: virtual void __cdecl `anonymous namespace'::NvidiaOpticalFlowImpl_2::calc(class cv::_InputArray const &,class cv::_InputArray const &,class cv::_InputOutputArray const &,class cv::cuda::Stream &,class cv::_InputArray const &,class cv::_OutputArray const &)" (?calc@NvidiaOpticalFlowImpl_2@?A0xf83298cd@@UEAAXAEBV_InputArray@cv@@0AEBV_InputOutputArray@4@AEAVStream@cuda@4@0AEBV_OutputArray@4@@Z)

This means that HAVE_NVIDIA_OPTFLOW macro has been defined in nvidiaOpticalFlow.cpp

#elif !defined HAVE_NVIDIA_OPTFLOW
 :
#else
 :
cv::cuda::device::optflow_nvidia::FlowUpsample((void*)m_flowXYcuDevPtr, nSrcWidth, nSrcPitch,...
 :
#endif

but not in nvidiaOpticalFlow.cu

#ifdef HAVE_NVIDIA_OPTFLOW
 :
void FlowUpsample(void* srcDevPtr, uint32_t nSrcWidth, uint32_t nSrcPitch, uint32_t nSrcHeight,
 :
#endif //HAVE_NVIDIA_OPTFLOW

The only reason I can imagine is that cmake cache (this is a general guess).
Any chance that you re-run the cmake on existing build directory ? (I really hate to say this but there's nothing else I can say, unless there is more clear reproducer)

[LaurentBerger]

Now I rebuild everything with -DBUILD_opencv_cudaoptflow=OFF I can test it twomorow now
When I built with cudaoptflow=ON I deleted all contents of my build opencv folder.

my cmakeoutput (empty build folder ) is

cmakeoutput.txt

line 306 : -- Building with NVIDIA Optical Flow API 2.0

[alalek]

@LaurentBerger You may want to fetch tags from upstream repository: git fetch -t upstream (use -t option)

Build error is confirmed.

[alalek]

Linux is failing too (with CUDA 10.0):

../..../../lib/libopencv_cudaoptflow.so.4.5.1: undefined reference to cv::cuda::device::optflow_nvidia::FlowUpsample(void*, unsigned int, unsigned int,/lib/libopencv_cudaoptflow.so.4.5.1: undefined reference to cv::cuda::device::optflow_nvidia::FlowUpsample(void*, unsigned int, unsigned int, unsigned int, void*, unsigned int, unsigned int, unsigned int, unsigned int)'
unsigned int, void*, unsigned int, unsigned int, unsigned int, unsigned int)'

relates #2824

[tomoaki0705]

My fault. I didn't confirm properly after #2824 was merged. My apologies.
Now #2836 lets the build pass.
