Opencv build did not generate opencv_world dll and only generates opencv_videoio_ffmpeg490_64 (OpenCV with CUDA))


Its my first time trying to build opencv library and im experimenting the same error in

Basically when i do the building process, the opencv_worldXXX.dll isnt generated and I get an error when thying to built a program with Visual Studio. The steps that i have done are the following (same of the following video:

  1. Download opencv latest release, opencv contrib, create a build folder and put them in same directory.

  2. Run CMake gui:
    i) Configure selecting VS code 2019 with x64
    ii) Configure checking these boxes: WITH_CUDA; OPENCV_DNN_CUDA; ENABLE_FAST_MATH; BUILD_opencv_world; Add the modules of contrib file to OPENCV_EXTRA_MODULES_PATH
    iii) Configure checking CUDA_FAST_MATH, changing the values of CUDA_ARCH_BIN to 7.5 (due i have a geforce 1650), and only configurating to Release the CMAKE_CONFIGURATION_TYPES.
    iv) Generate

  3. Run cmake --build “{Path}\build” --target INSTALL --config Release

When it ends, it creates {path}\build\install\x64\vc16\bin directory that only contains this file opencv_videoio_ffmpeg490_64.dll . Why isnt the opencv_world.dll generating, if i have checked the BUILD_opencv_world box? In the cmake GUI terminal also tells some things are missing, but I dont know if they are the source of my error:

The errors from the output window. I want to see the first error which is generated along with the associated text please.

If i built using the following command:
cmake --build “{Path}\build” --target INSTALL --config Release
No error windows pop up, but in the cmd a red warning appears (translated):

error C3861: ‘cudnnSetRNNDescriptor_v6’: identifier not found [C:\Users\FranciscoAguilera\Documents\Op

Also, there is no “/install” directory created, so i cant add the bin folder to the path:

I dont understand what I have done. Now Im running another compile using Visual Studio 2022, Built ALL_BUILD and then INSTALL. Once is done, i can show you what i get

I built with VS and the same error messages appears that I show at the start of the post. Building with Visual studio creates de /install folder and I get the bin and lib folder, so I add them to the Path in env. variables. Now, if i try to build and run this code:


cmake_minimum_required(VERSION 3.0.0)
project(test_opencv VERSION 0.1.0)


find_package( OpenCV REQUIRED)
include_directories( ${OpenCV_INCLUDE_DIRS} )

add_executable(test_opencv main.cpp)

target_link_libraries( test_opencv ${OpenCV_LIBS})



#include <iostream>
#include <opencv2/dnn.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/highgui.hpp>
#include <iostream>
#include <opencv2/core/cuda.hpp>

using namespace std;
using namespace cv;
using namespace dnn;
using namespace cuda;

int main(int, char**) {


    cout << "Hello, world!\n";

The following errors shows up:

It look like OpenCV doesn’t support cuDNN 9.0.

I suggest using 8.9.7 instead which I don’t doesn’t generate the above error on my system.

Thank you, I changed cudnn version, restart PC and it worked!!!
After a week trying to install opencv with cuda im so happy to finally work. Really apreciate your help
