Mac OS X
Xcode is required on Mac OSX to install Feel++.
The easiest way to do so is to go through the Apple Store application and to search for Xcode. Xcode will provide the programming environment, e.g clang, for the next steps.
Introduction to HomeBrew
Homebrew is a free/open source software introduced to simplify the installation of other free/open source software on MacOS X. Homebrew is distributed under the BSD 2 Clause (NetBSD) license. For more information, visit their website.
To install the latest version of Homebrew, simply visit their website and follow the instructions. Each new package Homebrew installs is built into an intermediate place called the Cellar (usually /usr/local/Cellar) and then the packages are symlinked into /usr/local (default).
Homebrew base command is
brew. Here is a list of base available commands:
brew doctor: Check if the system has any problem with the current installation of Homebrew;
brew install mypackage: This command installs the package mypackage;
brew install [--devel|--HEAD] mypackage: These options respectively installs either the development version or the HEAD version of the package mypackage, if such versions are specified in the Formula file;
brew uninstall mypackage: This command allows to uninstall the package mypackage.
This section is aimed at users that do not have Homebrew already installed.
In order to build Feel++ from Homebrew, you have to do the following steps:
First install Homebrew
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
then check your Homebrew installation and fix warnings/errors if necessary
$ brew doctor
Install Homebrew-science tap to get the scientific software recommended or suggested for Feel++.
$ brew tap homebrew/homebrew-science
you should see something like
==> Tapping homebrew/science Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-science'... remote: Counting objects: 661, done. remote: Compressing objects: 100% (656/656), done. remote: Total 661 (delta 0), reused 65 (delta 0), pack-reused 0 Receiving objects: 100% (661/661), 591.93 KiB | 0 bytes/s, done. Tapped 644 formulae (680 files, 1.9M)
Next you install Feel++ tap with
brew tap feelpp/homebrew-feelpp
you should read something like
==> Tapping feelpp/feelpp Cloning into '/usr/local/Homebrew/Library/Taps/feelpp/homebrew-feelpp'... remote: Counting objects: 5, done. remote: Compressing objects: 100% (5/5), done. remote: Total 5 (delta 0), reused 4 (delta 0), pack-reused 0 Unpacking objects: 100% (5/5), done. Tapped 1 formula (30 files, 60.7K)
The final step is to either install Feel++
$ brew install feelpp
or just Feel++ dependencies if you plan to build Feel++ from sources yourself
$ brew install --only-dependencies feelpp
Note If you encounter problems, you can fix them using
brew doctor. A frequent issue is to force
brew link --overwrite open-mpi
If Homebrew is already installed on your system, you might want to customize your installation for the correct dependencies to be met for Feel++.
You can browse Feel++ dependencies using the following command:
$ brew deps feelpp | column
you get the list of formulas Feel++ depends on for its installation
ann fftw libtool slepc arpack gcc metis suite-sparse autoconf glpk mumps sundials automake gmp netcdf superlu boost gmsh open-mpi superlu_dist cln hdf5 parmetis szip cmake hwloc petsc tbb eigen hypre scalapack veclibfort
If you want to customize the compilation process for a dependency (Set debug mode, Remove checking steps, Remove the link with certain libraries, etc.), you can access to the building options with the
info flag. For exemple, with open-mpi:
$ brew info open-mpi
You get various information about the
open-mpi: stable 2.0.1 (bottled), HEAD High performance message passing library https://www.open-mpi.org/ Conflicts with: lcdf-typetools, mpich /usr/local/Cellar/open-mpi/2.0.1 (688 files, 8.6M) * Built from source on 2016-09-26 at 10:36:46 with: --c++11 --with-mpi-thread-multiple From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/open-mpi.rb ==> Dependencies Required: libevent ✔ ==> Requirements Recommended: fortran ✔ Optional: java ✔ ==> Options --c++11 Build using C++11 mode --with-cxx-bindings Enable C++ MPI bindings (deprecated as of MPI-3.0) --with-java Build with java support --with-mpi-thread-multiple Enable MPI_THREAD_MULTIPLE --without-fortran Build without fortran support --HEAD Install HEAD version
Then, you then just have to pass the needed flags, when installing the dependency.
boosthas to be installed with mpi and c++11 support and
mumpsneeds to be installed with the following scotch5 support.
MacPorts is an open-source community projet which aims to design an easy-to-use system for compiling, installing and upgrading open-source software on Mac OS X operating system. It is distributed under BSD License and facilitate the access to thousands of ports (software) without installing or compiling open-source software. MacPorts provides a single software tree which includes the latest stable releases of approximately 17700 ports targeting the current Mac OS X release (10.9). If you want more information, please visit their website.
To install the latest version of MacPorts, please go
MacPorts page and follow the instructions. The simplest way is to
install it with the Mac OS X Installer using the
provided on their website. It is recommended that you install X11 (X Window System) which is normally used to display X11 applications.
If you have installed with the package installer (
MacPorts-2.x.x.pkg) that means MacPorts will be installed in
/opt/local. From now on, we will suppose that macports has
been installed in
/opt/local which is the default MacPorts
location. Note that from now on, all tools installed by MacPorts will be installed in
for example (that’s here you’ll find gcc4.7 or later e.g
/opt/local/bin/g++-mp-4.7 once being installed).
In your command-line, the software MacPorts is called by the command
port. Here is a list of key commands for using MacPorts, if you want more informations please go to MacPorts Commands.
sudo port -v selfupdate: This action should be used regularly to update the local tree with the global MacPorts ports. The option
-venables verbose which generates verbose messages.
port info mypackage: This action is used to get information about a port. (description, license, maintainer, etc.)
sudo port install mypackage: This action install the port mypackage.
sudo port uninstall mypackage: This action uninstall the port mypackage.
port installed: This action displays all ports installed and their versions, variants and activation status. You can also use the
-voption to also display the platform and CPU architecture(s) for which the ports were built, and any variants which were explicitly negated.
sudo port upgrade mypackage: This action updgrades installed ports and their dependencies when a
Portfilein the repository has been updated. To avoid the upgrade of a port’s dependencies, use the option
A Portfile is a TCL script which usually contains simple
keyword values and TCL expressions. Each package/port has a
corresponding Portfile but it’s only a part of a port description.
Feel++ provides some mandatory Portfiles for its compilation which are either not available in MacPorts or are buggy but Feel++ also provides some Portfiles which are already available in MacPorts such as gmsh or petsc. They usually provide either some fixes to ensure Feel++ works properly or new version not yet available in MacPorts. These Portfiles are installed in
To be able to install Feel++, add the following line in
/opt/local/etc/macports/source.conf at the top of the file
before any other sources:
file:///<path to feel top directory>/ports/macosx/macports
Once it’s done, type in a command-line:
$ cd <your path to feel top directory>/ports/macosx/macports $ sudo portindex -f
You should have an output like this:
Reading port index in $<$your path to feel top directory$>$/ports/macosx/macports Adding port science/feel++ Adding port science/gmsh Adding port science/petsc Total number of ports parsed: 3 Ports successfully parsed: 3 Ports failed: 0 Up-to-date ports skipped: 0
Your are now able to type
$ sudo port install feel++
It might take some time (possibly an entire day) to compile all the requirements for Feel++ to compile properly. If you have several cores on your MacBook Pro, iMac or MacBook, we suggest that you configure macports to use all or some of them.
To do that uncomment the following line in the file
buildmakejobs 0 $\#$ all the cores
At the end of the
sudo port install feel++, you have all
dependencies installed. To build all the Makefile,
automatically launched but can have some libraries may not be found but they are not mandatory for build Feel++, only the features related to the missing libraries will be missing.
