Download OpenCV for Android and iOS: https://opencv.org/releases/ 16 | 2. Copy or create symlinks: 17 | - `opencv2.framework` to `native_opencv/ios` 18 | - `OpenCV-android-sdk/sdk/native/jni/include` to `native_opencv` 19 | - Contents of `OpenCV-android-sdk/sdk/native/libs/**` to `native_opencv/android/src/main/jniLibs/**` 20 | 21 | ## Windows 22 | 23 | Run `init_windows.ps1` PowerShell script from a `scripts` folder or do the following steps manually: 24 | 25 | 1. Download OpenCV for Windows: https://opencv.org/releases/ 26 | 2. Unpack it. Set env. variable `OpenCV_DIR` to unpacked `...\opencv\build` folder 27 | 3. Create a hard link from `native_opencv\ios\Classes\native_opencv.cpp` to `native_opencv_windows\windows\native_opencv.cpp` 28 | 4. Make sure `native_opencv_windows\windows\CMakeLists.txt` contains correct .dll names (OpenCV_DEBUG_DLL_NAME,OpenCV_RELEASE_DLL_NAME) 29 | 30 | ## macOS 31 | 32 | Before doing anything else, you need to download OpenCV source code and 33 | build a framework by running `opencv/platforms/apple/build_xcframework.py` script. 34 | 35 | Run `init_macos.sh` script from a `scripts` folder or do the following steps manually: 36 | 37 | 1.
