You need to install latest Xcode and the command line tools. Then install macports.
Install openmpi from macports
sudo port install openmpi
Install tbb from macports
sudo port install tbb
Install hdf5 from macports
sudo port install hdf5-18 +openmpi +fortran
Install metis from macports
sudo port install metis
Install PETSC from macports. You need to modify the port file to include hypre support. Edit the following file
/opt/local/var/macports/sources/rsync.macports.org/release/ports/math/petsc/Portfile
and add following entry in the configure section
--download-hypre
Then install petsc
sudo port install petsc
If you upgrade petsc later, make sure to make above change to Portfile.
Install SLEPC from macports
sudo port install slepc
Install arpack from macports
sudo port install arpack
Install p4est. I used the script given on deal.II website except that you need to specify the openmpicc and openmpif77 as compilers. Add following lines to the script at two places, once for FAST version and once for DEBUG version.
CC=openmpicc F77=openmpif77
Then run (put correct p4est version)
sudo ./p4est-setup.sh p4est-x-y-z.tar.gz /opt/p4est
I installed the mac binary of doxygen which you can get from their website. You need this only if you want to build the documentation yourself. I recommend downloading the documentation from the deal.II website.
Install deal.II
