[Gretl-users] gretl for Windows on arm64

Some people have expressed interest in running gretl on arm64 Windows. Well, we've started work on this and there's now a native arm64 package available for testing, at https://sourceforge.net/projects/gretl/files/snapshots/gretl_install-arm6... I've tested on a Surface X Elite running Windows 11 and it seems to work nicely. We'd be grateful if people are willing to give it a try and report any problems. Two limitations to note: First, parallelization via MPI is not yet working. Microsoft's MS-MPI is not available for arm64, and probably never will be. I've put some effort into trying to port Open MPI but have not yet succeeded. Second, the X-13ARIMA-SEATS (x13as) add-on package for gretl is not available in a native arm64 version, since there's not yet a sufficiently functional fortran compiler for arm64. However, Windows 11 on arm64 supports x64 emulation, and if you want to use x13as with gretl, there's an installer for the x64 version which is tested as working OK on arm64: https://sourceforge.net/projects/gretl/files/x13as/x13as_install-64.exe Allin Cottrell
