[Gretl-users] gretl extras for macOS

Hello all, I've recently checked and updated the various "optional extras" available for gretl on Mac. Here's the current status. 1) X-13ARIMA In https://sourceforge.net/projects/gretl/files/x13as/ you can find x13as-mac-intel.tar.gz x13as-mac-arm64.tar.gz which can be installed from within gretl with the command pkg install <package-file> 2) TRAMO/SEATS In https://sourceforge.net/projects/gretl/files/tramo/ you can find tramo-seats-mac-intel.tar.gz tramo-seats-mac-arm64.tar.gz which can also be installed via "pkg install". 3) MPI In https://sourceforge.net/projects/gretl/files/mpi we have openmpi-1.6.5-mac-intel.tar.xz openmpi-4.1.5-mac-arm64.tar.xz These cannot be installed via "pkg install" but there are instructions in the README in the mpi directory, and also in the current MPI guide: https://sourceforge.net/projects/gretl/files/manual/gretl-mpi.pdf HOWEVER, please note that a little hack is required to get MPI 4.1.5 working on arm64 with gretl 2023b (or earlier). After installing the package into your root directory, navigate (in a Terminal window) to the "/opt" directory and create a symlink: cd /opt sudo ln -s openmpi openmpi-4.1 After this the command "ls -l" should show, inter alia, openmpi-4.1 -> openmpi This hack is not needed for the July 31 snapshot or later.
