OpenCV on Windows 10 with NetBeans IDE 8.1 not working

I have installed the latest version of OpenCV. Now I'm trying to configure NetBeans to use it. I put ../../../../../opencv/build/include in the C++ compiler and in the Linker ../../../../../opencv/build/x64/vc14/lib with the libraries opencv_world310 and opencv_world310d. I'm using Cygwin. When I build a simple project I receive the message BUILD FAILED (exit value 2, total time: 1s).

Thank you very much!

you cannot use the prebuild visual studio libs with mingw.

if you insist on using a cygwin environment, you will have to build the opencv libs locally, using cmake (and please use mingw64, not mingw32)

pretty similar to here , you can skip all the dependancies on win.

Probably I'm missing something. I'm using Cygwin64 and no online guide say to build the opencv libs locally. Can you be more precise and explane what command i have to do? I try to build it like on ubuntu but I receive the message "..does not appear to contain CMakeLists". I have to make a new folder build? Where? I don't understand.. Thank you very much for the help! After two days of trying I see the possibility to make it work!

" I have to make a new folder build?" - yes. and you have to cd into it, and run cmake from there

"Where? " -- it does not matter.

last: cmake (some args) <path-to-opencv-src-dir>

Perfect! I receive -- Configuring done -- Generating done -- Build files have been written to: /build Now I think I have to change the path in NetBeans to this folder. It is correct?

sorry i never use netbeans, so idk.

but maybe, it's a good idea, to generate plain unix makefiles to build the libs (see cmake -G) , and later use cmake again to generate netbeans project for your own project
