Install OpenCV C++ on Windows with MinGW Compiler

OpenCV (Open Source Computer Vision Library) is a library of programming functions mainly aimed at real-time computer vision, developed by Intel, The library is cross-platform and free for use . OpenCV features GPU acceleration for real-time operations . MinGW is a native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications

Thank you very much for the OpenCV MinGW file. Didn't work when I tried another OpenCV MinGW file. Greatly appreciated.

Thank you sir!!! It finally worked after I followed your video 😭👍

I am on my last nerve with building this library. The documentation is worse than I would have expected for such an ubiquitous and powerful tool. Thank you for this underrated advice. This is the first I'm hearing of OpenCV not coming with prebuilt lib files for mingw64 compiler. This is exactly what is causing my problems. In my mingw32-make log, I have been encountering errors at the linking step, directly after the examples are built (I selected generate examples and world module in cmake generator). Further investigation on StackOverflow has shown me that this is due to these missing prebuilt libraries which may exist in certain versions of windows- things like libgdi32.a, etc.

How did you find these files for your version? I am attempting for the latest version to date, which is 4.5.2. Thank you for creating this tutorial. I seriously wanted to throw up. Hopefully I can find the files and make this version work. If not, I will probably go for v3

Hello! I need some help, I'm getting a DLL procedure entry point error whenever I compile anything with opencv. Thanks!

Nice video but I wanted to see what the Makefile looked like. I guess I'm gonna have to learn cmake 😄

Whenever I download the MinGW it downloads a zip file with a ton of folders but none of them are bin nor any application installer file. Am I doing something wrong?
