OpenCV-MinGW-Build is a toolkit and set of build scripts that make it easier to compile OpenCV with the MinGW (Minimalist GNU for Windows) toolchain on Windows platforms. OpenCV itself is a widely used open-source computer vision and machine learning library, but building it on Windows with MinGW can be tricky due to compiler and dependency mismatches, configuration quirks, and platform differences. This repository packages automation, patched CMake configs, and step-by-step instructions so you can generate OpenCV binaries that work with MinGW GCC rather than being tied to MSVC (Microsoft Visual C++). This is especially useful for developers who prefer the GNU toolchain or who need a consistent cross-platform compile environment that matches Linux and macOS workflows. By smoothing out the build process and reducing manual configuration, it allows users to experiment with OpenCV features, prototype vision workflows, or integrate OpenCV into MinGW-based projects more reliably.
Features
- MinGW-focused build automation for OpenCV on Windows
- CMake configuration patches for compiler compatibility
- Reduces manual steps in building OpenCV with GCC on Windows
- Useful for cross-platform codebases that avoid MSVC
- Supports typical OpenCV modules and extensions
- Developer-friendly instructions for reproducible builds
