# OpenCV-MinGW-Build MinGW version of OpenCV compiled on Windows. ## [OpenCV 3.4.1](https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-3.4.1) ``` git clone -b OpenCV-3.4.1 [email protected]:huihut/OpenCV-MinGW-Build.git ``` ## [OpenCV 3.3.1](https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-3.3.1) ``` git clone -b OpenCV-3.3.1 [email protected]:huihut/OpenCV-MinGW-Build.git ``` ## Compiling Environment * Windows-10-64bit * MinGW-5.3.0-32bit * CMake-3.9.2 ## How to compile OpenCV * [wiki.qt . How to setup Qt and openCV on Windows](https://wiki.qt.io/How_to_setup_Qt_and_openCV_on_Windows) * [blog.huihut . OpenCV使用CMake和MinGW的编译安装及其在Qt配置运行](https://blog.huihut.com/2017/12/03/CompiledOpenCVRunInQt/) ## Using OpenCV in Qt Add OpenCV library file and include path to Qt `.pro` file. * My version of OpenCV : `OpenCV 3.3.1` * My OpenCV path : `E:\OpenCV_3.3.1\OpenCV-MinGW-Build` So the configuration is as follows (**You need to modify it according to your OpenCV.**) : ``` win32 { INCLUDEPATH += E:\OpenCV_3.3.1\OpenCV-MinGW-Build\include LIBS += E:\OpenCV_3.3.1\OpenCV-MinGW-Build\bin\libopencv_*.dll } ``` or ``` win32 { INCLUDEPATH += E:\OpenCV_3.3.1\OpenCV-MinGW-Build\include LIBS += -LE:\OpenCV_3.3.1\OpenCV-MinGW-Build\bin \ -llibopencv_calib3d331 \ -llibopencv_core331 \ -llibopencv_dnn331 \ -llibopencv_features2d331 \ -llibopencv_flann331 \ -llibopencv_highgui331 \ -llibopencv_imgcodecs331 \ -llibopencv_imgproc331 \ -llibopencv_ml331 \ -llibopencv_objdetect331 \ -llibopencv_photo331 \ -llibopencv_shape331 \ -llibopencv_stitching331 \ -llibopencv_superres331 \ -llibopencv_video331 \ -llibopencv_videoio331 \ -llibopencv_videostab331 } ```
