Great tutorial, easy to follow, got further with this one than any other! one problem now, no VS files in the build folder? So I can go on to the next step... any cles boss?
When I come to the part where I want to add the modules into -> OPENCV_EXTRA_MODULES_PATH, cmake crashes after entering the opencv_contrib-master path. Any ideas?
Just wrote the path to the file by hand or copy-paste it.. when you copy the path sometime he wrote the path like c:desktop\opencv\.. then you have to switch the "\" with "/". Like c:desktop/opencv/..
really nice video.. i have been using the pyimgesearch examples for the raspberry-pi and decided to go back to opencv with the visual studio 2019 version. thanks for the great info...:)
It sounds like either the path to the library files are either not added to VS or is incorrect. You might try referencing this Stack Overflow thread: stackoverflow.com/questions/21744464/opencv-error-link-fatal-error-lnk1104-cannot-open-file-opencv-core231d-lib
Nice video, i need your help.. can i build facial expression recognition program through the steps you showed here? If yes can you please recommend a video for me. Thanks a lot.. keep going
I follow your steps by Visual Studio 2019, however, something went wrong while building the INSTALL under CMake Targets Including：“can't open vgg_generated_1 opencv_xfeatures2d20.i" etc. Could you help me what was wrong ?
please i have a problem i install it and i can show image but not video. and i saw that many Gstreamer on cmake are missing example:GSTREAMER_app_LIBRARY-NOTFOUND,GSTREAMER_base_LIBRARY.... and in visual studio i cannot play a video because the coresponding dll are already missing. thanks if you could have a solution
Thanks for the guide! I am having some trouble after I include OpenCV in my codebase. I can use things like cv::Mat, but when I try to use cv::erode, I get a linker error. There seems to be more libs in build/lib/debug then are present in the install directory. Could that be the issue?
hey if anyone gets an error while building related with python, check out whether python 2.7 is up within the environment variables, that should solve the problem... happens when you installed Anaconda after python 2.7. Cheers and thank you very much for the video :) !

what need to be done so it work on pycharm?
laptop crashed when i tried building the solution , can i skip the process ? or will it affect my installation
Awesome video thank you! I have an error code MSB8066 when building in both debug and release. Any help would be appreciated!
you might need to add C:\opencv\x64\vc16\bin to your path environment variables if it can't find .dll's
I got a bunch Errors when building the release, many missing modules, anyone had this problem?
i had it
It's because you do not run Visual Studio as administrator, this worked for me
Oh really? Imma try that, thanks
I tried to run VS as admin, but still got the same bunch of errors, anyone resolved this?
please use the source code of the website atm the github do not contain the include folder so will always fail
nice video! hope to see your new video!
Extra modules dosent work for me. Cmake creates a error.
What's the error?
Also mine
It's : Error in configuration process, project files may be invalid
@@toptenofficial6671 i have this error too
You guys sure you're selecting the 'modules' folder and not the entire 'contrib' one?

Hii, this tutorial work for visual studio 2019??
Yep, just download cmake v3.15.0-rc2 from cmake.org/download/ . This version can generate the solution files for visual studio 2019
@@qwertyui118 i dont see v3.15.0-rc2 there. Would there be another one?
@@claracardosoferreira5595 Dude, that was a year ago. It's been superseded.
Why using cmake?
What python version should be installed?
Thank you
