We usually suggest people use MSVC as the C and C++ compilers to work with the WAMR repository on Windows. The community also uses MinGW as their development environment. product-mini/platforms/windows is a good starting point as well.

I hope you're doing well! It seems like there hasn't been any activity on this issue for a while. If you have any further questions or updates, please feel free to share them with us.

To keep our project organized, we plan to close this issue soon if there are no new developments. Of course, you can always reopen it or start a new thread if needed.

Thank you for your understanding and cooperation!
