Issue while compiling opencv with cuda enabled

CAPED_CRUSADER01 · April 4, 2023, 6:53am

Hi
I’m compiling opencv with cuda enabled for gpu acceleration. I installed cuda stuff, I have anaconda already installed, installed vs2022 with c++ and build tools. After using generate in cmake-gui, I recieved an error(Error 1: OpenCV does not recognize MSVC_VERSION 1924). I proceeded regardless and tried to build in vs2022 but its failing with most of the issues relating to syntax errors. Can someone guide me in the right direction?
OS: Windows 11 22H2
Conda Python: 3.9
Cmake: 3.26
Visual studio: 2022

This doesn’t look like it has anything to do with CUDA being enabled.

OpenCV 4.5.2 was released before Visual Studio 2022 (vc17)

            elseif(MSVC_VERSION EQUAL 1600)
              set(OpenCV_RUNTIME vc10)
            elseif(MSVC_VERSION EQUAL 1700)
              set(OpenCV_RUNTIME vc11)
            elseif(MSVC_VERSION EQUAL 1800)
              set(OpenCV_RUNTIME vc12)
            elseif(MSVC_VERSION EQUAL 1900)
              set(OpenCV_RUNTIME vc14)
            elseif(MSVC_VERSION MATCHES "^191[0-9]$")
              set(OpenCV_RUNTIME vc15)
            elseif(MSVC_VERSION MATCHES "^192[0-9]$")
              set(OpenCV_RUNTIME vc16)
            else()
              message(WARNING "OpenCV does not recognize MSVC_VERSION \"${MSVC_VERSION}\". Cannot set OpenCV_RUNTIME")
            endif()
          elseif(MINGW)
            set(OpenCV_RUNTIME mingw)
          
          
  if(CMAKE_SYSTEM_PROCESSOR MATCHES "amd64.*|x86_64.*|AMD64.*")
              set(OpenCV_ARCH x64)
            else()

Try using OpenCV >= 4.54

              set(OpenCV_RUNTIME vc12)

            else()
              message(WARNING "OpenCV does not recognize MSVC_VERSION \"${MSVC_VERSION}\". Cannot set OpenCV_RUNTIME")
            endif()
          elseif(MINGW)
            set(OpenCV_RUNTIME mingw)
          
          
  if(CMAKE_SYSTEM_PROCESSOR MATCHES "amd64.*|x86_64.*|AMD64.*")
              set(OpenCV_ARCH x64)
            else()

after cleaning your build directory to see if this resolves your issue.
