I am seeking assistance with an error I encountered while building OpenFHE on a Windows system using MinGW64. Below are the details of my setup and the error message.

@techman You can link OpenFHE v1.2 with g+±12 or any earlier version. We will address all g+±14 errors in the next release. Meanwhile, you can obtain older versions of MSYS2 [here](https://github.com/msys2/msys2-installer/releases). ---

Hi Guys, I have resolved the issue. I would like to add that obtaining old older versions of MSYS2 would not resolve the issue if you execute the command pacman -Syu. In my case it reverts back to g++14. So, you should ignore that command to resolve the issue. ---
