Create an OpenCV 4 Project in Visual Studio [C++]

[@aparna2701]

You have ABSOLUTELY no idea how much you have helped me here. I may have just passed my course because of your wonderful setup video. PLEASE don't stop making more videos, your channel and you are LOVELY.

[@RaviPrakash-dz9fm]

Bro! You saved my job!!! I can't be more grateful to you. I used to do all this in Python, but my boss told me to use C++. Thanks a lot.

[@robertt.9211]

What a wonderful tutorial! Very detailed and every intermediate step perfectly explained. I spent min. 10 hours with other bad inconsistent tutorials and almost despaired. I am so incredibly grateful to you!!!

[@OutLan]

Wow. I never knew the ALT+SHIFT+I trick. You learn something new every day.

[@adamhacks8437]

I'm a sucker for keyboard shortcuts. I had to fight the temptation to do it in vim, since I figured VS Code is a bit more approachable.

[@lukasijus8690]

That is a pure gold info. I remember couple of years ago doing this on my own for at least couple of painful days. Thanks Captain!

[@BartoszKomar]

I've just set-up project with OpenCV 4.52 so your tutorial is still actual. Thanks a lot!

[@RogerCh888]

You're a life saver, thank you for the initial build and installation video and this setup video, these videos were so helpful.

[@taktail]

thank you. you fixed my depression and brain bleed from trying to figure this out.

[@Amonomen]

For anyone reading this, save yourself some time in configuring the additional dependencies and use the command "dir /B *d.lib > debugLib.txt" Great video! It's been so long since I've messed with C++ that I forgot how to setup the libraries for a project.

[@MegaCplayer]

Great video! Tip: Use powershell instead to get libraries Get all d.lib: Get-ChildItem "C:\yourpath" -Name -Filter *d.lib Get all non d.lib: Get-ChildItem "C:\yourpath" -Name -Exclude *d.lib

[@lostree1785]

THANK YOU SO MUCH FOR THIS TUTORIAL!!!

[@Iluvbabaganush123]

I did exactly the steps followed and however the opencv/tracking.hpp is not working. When I try to include that libaray into my opencv source file it shows an error. I have google so much unfortunately nothing has come of it. I configured using make and have done the solution build more the 10 times now. With no progress.

[@MauFeitioO]

I just want to say that i love you, thanks for the help, openCV and visual studio were getting me crazy

[@garybey3800]

Thank you. Your video saved me a lot of trouble.

[@santoshkumarjami9326]

Really such a nice and clear explanation which saved my time and created interest in learning OpenCV. Thanks a lot

[@AntsaVRmusic]

Hi ! any idea on how to use openCV in a CLR project? I actually want to display the video in a winForm , but I don't know how to do it.

[@aaaron19]

I am having trouble making my app standalone, I get errors about not having OpenCV, etc. when on other machines. So if I wanted to make my application a standalone EXE that I could send to anyone, I would make my project inside the build folder that we created because that contains all the OpenCV files. Then I just need to build in release and it should be good?

[@davidhernandezjuarez172]

Amazing bro, you saved me

[@simplex2168]

I did everything you explained and got an error on my test project that says that opencv_core411.dll cannot be found. I did rebuild both debug and release konfiguration. Do you know what's up?

[@simplex2168]

By the way your tutorial was amazing and easy to follow.

[@simplex2168]

I found the issue. I did't have the opencv_world411d.lib inside my references, because I installed opencv wrongly and reinstalled it so I had the opencv_world411d.lib file.

[@datisreyhani4641]

Is it possible you could attach a fully configured file in the description? It's not working at all and I really need a project that runs openCV! Thanks

Awesome video, made it super easy to get started with OpenCV Development. Thanks.

I followed all the steps without any failures, still couldn't write the '#include' statement. Please help.

[@karayakar]

Great tutorial, opencv 4.3.0 tested and works. I had an issue with the libraries, after recompiling release and debug I was able to solve. Thanks.

[@fleurvanille7668]

@@Serialphotog what should I do please

[@adamhacks8437]

@@fleurvanille7668 I'd suggest going back to the part 1 video where I showed how to build the OpenCV library. Particularly, the part within Visual Studio that talks about building the library from within there. You have to do two separate build steps. Once to build the release version and then again with the debug version selected.

Hey, I'm trying building Opencv similar to you from source code, but for me all modules are not configured. I have checked all version similarity and stuff. Can you please help me

[@ANdrewPHillip16]

Hi, thanks for the tutorial, I did it all as you said but I have some problems with the Gstreamer DLLs, when I run the project I get a message telling me that it couldn't find a DLL, Do you know how can I solve this? Thanks for your help.

[@wkwkwk7347]

i've do the same thing but error message like this: Unable to start program 'c\users\ikhsn\documents\visual studio 2015\Project\Test1\x64\Debug\Test1.exe' The system cannot find the file specified.

[@yagzarkayn2178]

You could also include the libraries by writing *412.lib and *412d.lib

[@jk-il1qs]

Hi, just wondering do you have any idea of an error " gfluidimgproc_func.simd.hpp not found". I'm runing an opencv project, built successfully, but got this error when executed.

[@SuperEB1994]

Do i have to change the settings in Properties everytime i create a new OpenCV-project?

[@maroquio]

You can create a new project model and use it when needed. Take a look at this link: docs.microsoft.com/en-us/visualstudio/extensibility/creating-custom-project-and-item-templates?view=vs-2019

[@okfine9077]

If you do not want to edit the properties settings every time you want to create a C++ with OpenCV, you should consider using property sheets.

[@rachelbrady8257]

So helpful, thank you!!

[@BOHICAMAN1]

Followed exactly except I am using OpenCV 4.3. Using build RELEASE 64bit. Followed placing the file/directories where you said,but got error "Severity Error LNK1181 cannot open input file 'objdetect430.lib' " on line 1. Line 1 is: #include . Any suggestions appreciated! Bob

if you can't find the .dll you might need to add C:\opencv\x64\vc16\bin to your path environment variables

Thank you saviour, Since this wasn't the first video i watched on getting opencv i have downloaded and destroyed my hard drive with probably 20 different opencv and other files that i thought i needed, anything to code in c++ i geuss. 🙃

[@killuahsmathetricks389]

I did everything the video said. I actually get even the exact same fail messages in my command. However the frame does not update. Is there any reason for that that is easily fixable? I already tried to just make my for loop run for a million steps, but that does not work as well. It only captures the first frame when I run the programm and then nothin happens anymore. Furthermore I just noticed, that I can include the library in the debug mode, but not in release mode. I had the same issue before but flipped. I could include it in release mode but not debug. Anybody got an idea for any of my problems? =(
