How to Build OpenVINO GenAI sample in windows using GNU compiler?

I have some error duration compilation：

but MSVC can work well.

Hi @Grandix, You're encountering errors during MinGW (GCC) compilation due to undefined references to OpenVINO GenAI symbols. OpenVINO is primarily designed, tested, and optimized for MSVC (Microsoft Visual C++) on Windows, and the official documentation and pre-built binaries are tailored for MSVC. While MinGW may work in some cases, it is not officially supported, and you may encounter compatibility issues that require manual adjustments. For the best results and seamless integration, MSVC is the recommended and officially supported compiler for building and running OpenVINO on Windows.

Thanks for your reply.
My application is developed and compiled on Windows using GNU. Is there any methods to integrate OpenVINO on windows?

@grandxin ,OpenVINO is primarily tested with MSVC (Microsoft Visual C++), so there could be challenges when using GNU tools like MinGW on Windows. Since MinGW is based on GCC (GNU Compiler Collection), you might encounter issues when linking OpenVINO's libraries, which are designed for MSVC. Here are some suggestions to address this:

1. Use dynamic libraries (.dll) instead of static .lib files, as MinGW may have compatibility issues with MSVC-specific static libraries.

2. Compile with g++ using appropriate flags to link OpenVINO’s shared libraries. For example:
   g++ -o my_application my_application.cpp -I"C:/Program Files(x86)/Intel/openvino/inference_engine/include" -L"C:/Program Files(x86)/Intel/openvino/inference_engine/lib" -lInferenceEngine

3. Use OpenVINO’s Inference Engine in your MinGW application to load and run models, following the usual OpenVINO API conventions.

However, If MinGW integration becomes too difficult, switching to MSVC is recommended since it provides better compatibility with OpenVINO.
