Previous remark was for static library use Now I tried dynamic libraries using case, but got linker error. | Severity | Code | Description | Project | File | Line | Suppression State | | --- | --- | --- | --- | --- | --- | --- | | Error | LNK1107 | invalid or corrupt file: cannot read at 0x390 | Project1 | C:\Users\Raivo\opencv\build\x64\vc15\bin\opencv\_videoio\_ffmpeg460\_64.dll | 1 | | ---

Yes I added this library ---

Remove it and refer to my reply to your previous question > [@VIsual Studio problems](https://forum.opencv.org/t/visual-studio-problems/12120/4): > > Are you adding C:\Users\Raivo\opencv-4.7.0\build\bin\Debug\opencv\_calib3d470d.dll to Properties-\>Linker-\>Input-\>Additional Dependencies? instead of C:\Users\Raivo\opencv-4.7.0\build\lib\Debug\opencv\_calib3d470d.dll? If so that’s your problem, you need to add the .lib to the linker for compilation and the .dll to your system/user path for runtime. ---

1. those are NOT meant to be linked directly, so remove it (the videoio module will load those dynamically, on its own) 2. (again !) IF AT ALL, add `.lib` files to your linker, not `.dll` ---

I reality I added .lib files for linker. I don’t know, why it looks for dll-s. ---

Sorry. I am novice in this forum. But I overcome this problem by installin opencv-4.6.0 from sources and it works fine ---

Version 4.7.0 don’t work properly. Libraries build gives error - Error C2001 newline in constant opencv\_objdetect C:\Users\Raivo\opencv-4.7.0\build\modules\objdetect\opencl\_kernels\_objdetect.cpp 817 And both static library example gives memory allocation error and dynamic library using example gives error on linking - | Severity | Code | Description | Project | File | Line | Suppression State | | --- | --- | --- | --- | --- | --- | --- | | Error | LNK1107 | invalid or corrupt file: cannot read at 0x368 | Project1 | C:\Users\Raivo\opencv-4.7.0\build\install\x64\vc17\bin\opencv\_calib3d470.dll | 1 | |
