Windows build error penfhe

Library Questions
1

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.

I followed the instructions here:

Installing OpenFHE on Windows — OpenFHE documentation

Steps I followed:

  1. download MSYS2
  2. start MSYS2 MINGW64
  3. pacman –Syu
  4. pacman –S mingw-w64-x86_64-gcc
  5. pacman –S mingw-w64-x86_64-cmake
  6. pacman –S make
  7. pcaman –S git
  8. git clone GitHub - openfheorg/openfhe-development: This is the development repository for the OpenFHE library. The current (stable) version is v1.2.0 (released on June 25, 2024).
  9. cd openfhe-development
  10. mkdir build
  11. cd build
  12. cmake … (something reports ‘failed’)
  13. pacman -S autoconf
  14. make –j

Error Message: While running the make command, I encountered the following error:

Could anyone provide guidance on how to resolve this error? Any help or pointers would be greatly appreciated.

@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.

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.

hey, could you elaborate on what the solution is, I might have the same issue

See how this was solved here

Get an old version: I used this: msys2-x86_64-20230318.exe

and then follow these steps:
I followed the instructions here:

Installing OpenFHE on Windows — OpenFHE documentation

Steps I followed:

  1. Install an old version of MSYS2
  2. Admin run MSYS2 MINGW64
  3. …
  4. pacman –S mingw-w64-x86_64-gcc
  5. pacman –S mingw-w64-x86_64-cmake
  6. pacman –S make
  7. pcaman –S git
  8. git clone GitHub - openfheorg/openfhe-development: This is the development repository for the OpenFHE library. The current (stable) version is v1.2.0 (released on June 25, 2024).
  9. cd openfhe-development
  10. mkdir build
  11. cd build
  12. cmake …
  13. pacman -S autoconf
  14. make –j
