OpenMCX Windows Platform Build Support?

[wissem01chiha]

Hi, thanks very much for the awesome work! however I was trying to build openmcx on Windows and encountered several build errors. Most of them were related to missing packages on Windows, such as libxml2 or issues with libiconv building.

Environment Setup

• Operating System: Windows 11 (SDK 10.0.26100.0)
• CMake: 4.3.3
• Generator: Tested with Visual Studio 17 2022 and MinGW Makefiles
• Compiler: MSVC 19.44.35226.0
• Editor: Visual Studio Code with CMake Tools extension

I have noticed that the last commit was about 3 years ago and last production commits was about 5 years, did the project died anyway? if so , how can i help to maintain it ?

I also think this is very unfortunate. We have for example committed a pull request years ago, that has not been accepted, yet.
Maybe we need to create a fork to maintain OpenMCx.
Is this project really dead @klausschuch ?

Thanks @ClemensLinnhoff

Hi @klausschuch any update on this ?
