LifeV on MacOS 10.12 - Sierra

This is meant as a small how-to for installing LifeV on MacOSx 10.12.4.

Remark On March 5th 2018, I (Simone) was not able to use the build_openmpi from the lifev-env. Therefore I suggest to use the installation instructions for openmpi below.

First you have to make sure that C[]{.underline} is natively installed. After installing xcode, run

 xcode-select --install

This is usually the case if you installed XCode. You can verify the installation with the following commands:

g++ --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.38)
Target: x86_64-apple-darwin16.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Make sure that you have a recent version of cmake installed. I had trouble with cmake 3.7.0_0 and then updated to 3.8.2_0:

sudo port upgrade cmake

gfortran

install gfortran with the MacOSX package dowloaded from\ http://gcc.gnu.org/wiki/GFortranBinaries#MacOS\ and verify that it is well installed:

gfortran --version
  GNU Fortran (GCC) 6.3.0
  Copyright (C) 2016 Free Software Foundation, Inc.
  This is free software; see the source for copying conditions.  There is NO
  warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Remark the package also installs other compilers:

ls /usr/local/gfortran/bin/
cpp*        gcc*        gcc-nm*     gcov*       gfortran*
g++*        gcc-ar*     gcc-ranlib* gcov-tool*

In my case, the PATH is set such that the system gcc is called.

openmpi

Download openmpi (version 2.1.1 in my case)

 tar -xzf openmpi-2.1.1.tar.bz2
 cd openmpi-2.1.1
 ./configure --prefix=/opt/openmpi
 make -j 4
 sudo make install

/opt/openmpi/bin/mpicc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

/opt/openmpi/bin/mpicc -show    
gcc -I/opt/openmpi/include -L/opt/openmpi/lib -lmpi

Now you are ready to follow the instructions on lifev-env.

Note that you already have installed openmpi in /opt/openmpi, remember to tell config.sh

export MPI_C_COMPILER=/opt/openmpi/bin/mpicc
export MPI_CXX_COMPILER=/opt/openmpi/bin/mpic++
export MPI_FORTRAN_COMPILER=/opt/openmpi/bin/mpif90
export MPI_EXEC=/opt/openmpi/bin/mpiexec

and comment the line

OPENMPI_INSTALL_DIR=${INSTALLS_DIR}/openmpi-${OPENMPI_VERSION}_install${BUILD_TYPE}
