Building on Mac High Sierra
This page is currently under development. Please excuse inconsistencies.
This details the building of GridPACK on a Macbook Pro running Mac OS X High Sierra (10.13.6). The build was aided by the use of MacPorts to install some prerequisite software. Super user or sudo permissions are required to install and manage MacPorts, but should not be required for any other task.
These instructions use a specific combination of compilers, MPI implementation, and MacPorts packages. Other combinations can be used, the one here happened to work for the author. If you choose some other combination, you're on your own.
The instructions below can be executed in a terminal. To bring one up, go under the "Utilities" folder in the application tray at the bottom of the screen and click on "Terminal".
The easiest way to get GridPACK going on Mac OS X is to use MacPorts to install (some of) the needed prerequisite software. MacPorts is free, open source system whereby various software packages can be installed and maintained on a Mac OS X system. Homebrew provides a similar capability, but the author has no experience with it.
The MacPorts project provides very good
installation instructions. They will not be repeated here. It is
assumed here that MacPorts was installed in
/opt/local, which is the
default. Most systems support
rsync, but if yours doesn't because of firewall issues, additional information and some workarounds can be found here.
After MacPorts installation,
/opt/local/bin needs to be in shell
search path. The easiest way to do this is to add
the top of
/etc/paths (superuser privileges required). Afterward, a reboot or
starting a new shell should make the
port command available on the
Packages from MacPorts
Install the CLang 6.0 compiler set, mpich MPI implementation, and Boost with Boost.MPI using the following:
sudo port install boost +clang60+mpich
Make the installed compilers and MPI wrappers the default.
sudo port select --set clang mp-clang-6.0 sudo port select --set mpi mpich-clang60-fortran
At this point, the compiler commands,
clang++, and MPI compiler
mpicc, will be available at the command line.
Install CMake and the GNU linear programming kit:
sudo port install cmake sudo port install glpk
Build Packages from Source
PETSc and Global Arrays need to be built from source. You need to
choose a path in which packages will be installed. Here the author
decided to use a single installation directory,
$HOME/gridpack. Directories or architecture variables that should be set to reflect local user environments are colored red.
PETSc, version 3.8.4
Download the PETSc source. It is recommended to unpack this in the
installation directory (
$HOME/gridpack). PETSc configuration requires that the
PETSC_DIR environment variable be set before configuration. Set the
PETSC_DIR to the directory it which the PETSc source was unpacked. If using a Bourne-based shell, like the Mac OS X default
/bin/bash, do something like
PETSC_DIR=$HOME/gridpack/petsc-3.8.4 export PETSC_DIR
Or, if using a C-shell,
setenv PETSC_DIR $HOME/gridpack/petsc-3.8.4
Some users encountered significant problems building PETSc, which seems to be related to using a newer version of Xcode. If you have problems configuring or compiling PETSc, you may be able to fix them by making the modifications described on our troubleshooting page.
Change into the PETSc source directory and configure and build PETSc using
cd $PETSC_DIR ./configure \ PETSC_ARCH=arch-macosx-clang-real-opt \ COPTFLAGS="-g -O2" \ CXXOPTFLAGS="-g -O2" \ FOPTFLAGS="-g -O2" \ --with-prefix="$HOME/gridpack" \ --with-mpi=1 \ --with-gnu-compilers=0 \ --with-cc=/opt/local/bin/mpicc \ --with-fc=/opt/local/bin/mpif90 \ --with-cxx=/opt/local/bin/mpicxx \ --with-clanguage=c++ \ --with-fortran-bindings=0 \ --with-scalar-type=real \ --with-precision=double \ --download-suitesparse=1 \ --download-superlu_dist=1 \ --download-parmetis=1 \ --download-metis=1 \ --download-f2cblaslapack=1 \ --download-mumps=0 \ --download-scalapack=1 \ --with-shared-libraries=0 \ --with-x=0 \ --with-valgrind=0 \ --with-mpiexec=mpiexec \ --with-debugging=0 make PETSC_DIR=$HOME/gridpack/petsc-3.8.4 PETSC_ARCH=arch-macosx-clang-real-opt all make PETSC_DIR=$HOME/gridpack/petsc-3.8.4 PETSC_ARCH=arch-macosx-clang-real-opt test
Global Arrays, version 5.7
mkdir build cd build ../configure \ --enable-cxx \ --disable-f77 \ --enable-i4 \ --with-mpi \ --with-mpi-ts \ --enable-autodetect=yes \ --prefix="$HOME/gridpack" \ --without-blas \ --without-lapack \ --without-scalapack \ --enable-shared=no \ --enable-static=yes \ MPICC=mpicc MPICXX=mpicxx MPIF77=mpif90 \ MPIEXEC=mpiexec MPIRUN=mpirun \ LDFLAGS="-L/opt/local/lib" make make install
CMake will work very hard to choose the wrong compiler. Make sure it uses the correct compiler by setting environment variables as follows. In a Bourne-like shell,
CC=/opt/local/bin/clang CXX=/opt/local/bin/clang++ export CC CXX
Or in a C-shell,
setenv CC /opt/local/bin/clang setenv CXX /opt/local/bin/clang++
Obtain the GridPACK release or development code and put it in a convenient directory, like
In the build directory (src/build here), configure, build, and test GridPACK with
rm -rf CMake* cmake \ -D GA_DIR:STRING="$HOME/gridpack" \ -D BOOST_ROOT:STRING="/opt/local" \ -D PETSC_DIR:PATH="$HOME/gridpack/petsc-3.8.4" \ -D PETSC_ARCH:STRING="arch-macosx-clang-real-opt" \ -D MPI_CXX_COMPILER:STRING='/opt/local/bin/mpicxx' \ -D MPI_C_COMPILER:STRING='/opt/local/bin/mpicc' \ -D MPIEXEC:STRING='/opt/local/bin/mpiexec' \ -D MPIEXEC_MAX_NUMPROCS:STRING="2" \ -D GRIDPACK_TEST_TIMEOUT:STRING=30 \ -D USE_GLPK:BOOL=ON \ -D GLPK_ROOT_DIR:PATH="/opt/local" \ -D CMAKE_INSTALL_PREFIX:PATH="$HOME/gridpack" \ .. make
It appears that at the time of writing the OpenMPI ports are not Boost or PETSc compatible. Stick with mpich.
Boost.MPI compiled with the stock XCode C++ compiler seems to have trouble with serialization needed in the GridPACK code. This may or may not be a real issue. Little effort was expended to track it down, since Boost.MPI appears to work fine on Mac OS X if compiled with another CLang-based compiler.
PETSc must be later than 3.8. Versions 3.7.x do not configure properly with up to date XCode. This is a known issue that was fixed in 3.8.x.
