Installation of the prerequisite software

• Installing on Ubuntu
• Installing on macOS
• Installing on Arch Linux
• Installing on Fedora 18
• Installing on Fedora 11
• Installing on RedHat (CentOS)
• Installing on Suse Linux

Before installing AMUSE several software packages must be installed. These software packages can be installed manually or with two prepared installation scripts. The installation scripts will install python and the other prerequisites in a user directory. No “root” access is required.

These are the packages AMUSE needs:

• Python (version >= 2.6)
• Numpy (version >= 1.3.0)
• HDF (version 1.6.5 - 1.8.x)
• h5py (version >= 1.2.0)
• MPI (OpenMPI or MPICH)
• mpi4py (version >= 1.0)
• nose (version >= 0.11)
• docutils (version >= 0.6)
• FFTW (version >= 3.0)
• GSL
• CMake (version >= 2.4)
• GMP (version >= 4.2.1)
• MPFR (version >= 2.3.1)

In the first two sections (compilers and installation_scripts) we explain how to use the two installation scripts to install AMUSE. In the last section (manual) we have specified the required packages with the needed version for each.

Compilers

To build AMUSE from source you need to have a working build environment. The AMUSE build system needs a C++ and fortan 90 compiler. Please check first if you have a working build environment on your system.

In Ubuntu you can setup the environment with (as root):

apt-get install build-essential curl g++ gfortran gettext zlib1g-dev

In Fedora you can setup the environment with (as root):

yum groupinstall "Development Tools" "Development Libraries"

Installation scripts

We have created two installation scripts to automate the installation of the required packages on a LINUX and OS.X system. These scripts will install these packages in a user directory. One script downloads and installs python while the other script downloads and installs the libraries and python packages. As everything is installed in a user directory these packages can be installed even if a version of the software is already installed on your system.

The scripts will download and install the software in a user directory. This user directory must be specified with the PREFIX environment variable. Before running the installation scripts you must set the PREFIX environment variable and update the path and library path. For shell (bash) you need to do:

export PREFIX=~/amuse/prerequisites
export PATH=${PREFIX}/bin:${PATH}
export LD_LIBRARY_PATH=${PREFIX}/lib:${LD_LIBRARY_PATH}

One script will download, build and install python on your system. The other script is written in Python and will download and install the other packages. Both scripts can be found in the doc/install directory.

To start the installation do:

# 1. Open a shell and go to the <doc/install> directory
>

# 2. Set the PREFIX, PATH and LD_LIBRARY_PATH environment variables:
> export PREFIX=~/amuse/prerequisites
> export PATH=${PREFIX}/bin:${PATH}
> export LD_LIBRARY_PATH=${PREFIX}/lib:${LD_LIBRARY_PATH}

# 3. Start the installation script for python
> ./install-python.sh

# 4. Start the installation script for the prerequisite packages
> ./install.py download
> ./install.py install

# 5. Update your PATH variable in your profile.
# Make sure the `${PREFIX}/bin` directory is the first entry in the PATH!

You should now be able to install AMUSE.

Using the installation scripts on macOS

For macOS you need to install XCode and a gfortran compiler first. The XCode development package is available at https://developer.apple.com/xcode/ or in the App Store.

The standard XCode release does not come with a gfortran compiler. Go to the HPC Mac OS X site for a recent gfortran compiler, compatible with the XCode tools.

After installing XCode and gfortan, follow the steps described in the previous paragraph.

Manually installing the prerequisites

Python

Python is probably already installed on your system. To check the version of python do:

> python --version
Python 2.6.2

You can download python from https://www.python.org.

Numpy

To check if numpy is installed on your system do:

> python -c 'import numpy; print numpy.version.version'
1.3.0

If this fails with an error or a version before 1.3 you need to install numpy. You can download numpy from http://www.numpy.org.

HDF5 library

HDF5 is a data format specification. The HDF group provides a C library to write and access HDF files.

To check if the HDF library is installed on your system do:

> h5ls -V
h5ls: Version 1.8.3

If this fails with an error or a version before 1.6.5 you need to install the HDF library. You can download HDF from https://www.hdfgroup.org/.

h5py

To access HDF5 files from python we use the h5py library.

To check if the h5py library is installed on your system do:

> python -c 'import h5py; print h5py.version.version'
1.2.0

If this fails with an error or a version before 1.2.0 you need to install h5py. You can download h5py from https://www.h5py.org.

docutils

To check if the python docutils are installed on your system do:

> python -c 'import docutils; print docutils.__version__'
0.6

If this fails with an error or a version before 0.6 you need to install docutils. You can download docutils from http://docutils.sourceforge.net/

MPI

The installed MPI framework must be MPI 2 compatible. AMUSE will work with MPICH or OpenMPI

MPICH

MPICH is a portable implementation of the MPI 2 standard.

To check if MPICH is installed on your system do:

> mpdhelp

The following mpd commands are available.  For usage of any specific one,
invoke it with the single argument --help .

mpd           start an mpd daemon
mpdtrace      show all mpds in ring
mpdboot       start a ring of daemons all at once
mpdringtest   test how long it takes
...

If this fails with an error you need to install MPICH or check for OpenMPI support. You can download MPICH from http://www.mpich.org.

OpenMPI

OpenMPI is another portable implementation of the MPI 2 standard

To check if OpenMPI is installed on your system do:

> mpicxx -v

If this fails with an error you need to install MPICH or OpenMPI support. Most examples in the dopcumentation assume OpenMPI. You can download OpenMPI from https://www.open-mpi.org/.

MPI4PY

To access MPI from python we use the mpi4py software. To check if the mpi4py library is installed on your system do:

> python -c 'import mpi4py; print mpi4py.__version__'
1.0.0

If this fails with an error or a version before 1.0 you need to install mpi4py. You can find mpi4py at https://mpi4py.readthedocs.io/.

Nose

Nose is an extension of the python testing framework. It is used for all unit testing in AMUSE.

To check if Nose is installed on your system do:

> nosetests --version
nosetests version 0.11.1
...

If this fails with an error or a version before 0.11 you need to install nose. You can download nose from http://somethingaboutorange.com/mrl/projects/nose/.

FFTW

FFTW is a C subroutine library for computing discrete Fourier transforms. To check for the availability of fftw on your system, you can use fftw-wisdom:

> fftw-wisdom --version
fftw-wisdom tool for FFTW version 3.2.1.

You can download the FFTW library from http://www.fftw.org.

GSL

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. To check for the availability of GSL on your system, you can use gsl-config:

> gsl-config --version
1.14

You can download GSL from http://www.gnu.org/software/gsl/.

CMake

CMake is a cross-platform, open-source build system. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice. CMake is used to build EVTwin. To check whether you have CMake installed on your system:

> cmake --version
cmake version 2.8.2

You can download CMake from https://cmake.org/download/.

GMP

GNU MP is a library for arbitrary precision arithmetic (ie, a bignum package). It can operate on signed integer, rational, and floating point numeric types. GMP is required for Adaptb (Accurate Dynamics with Arbitrary Precision by Tjarda Boekholt). The best way to check whether you have the right version of GMP installed on your system depends on the package manager you use, but this should always work (note that the library numbers do not match the release version):

> locate libgmp
/usr/lib64/libgmp.so
/usr/lib64/libgmp.so.10
/usr/lib64/libgmp.so.10.0.3

> locate gmp.h
/usr/include/gmp.h

> grep GNU_MP_VERSION /usr/include/gmp.h
#define __GNU_MP_VERSION 5
#define __GNU_MP_VERSION_MINOR 0
#define __GNU_MP_VERSION_PATCHLEVEL 3

You can download GMP from https://gmplib.org.

MPFR

The MPFR library is a C library for multiple-precision floating-point computations with correct rounding. MPFR is required for Adaptb (Accurate Dynamics with Arbitrary Precision by Tjarda Boekholt). The best way to check whether you have the right version of MPFR installed on your system depends on the package manager you use, but this should always work (note that the library numbers do not match the release version):

> locate libmpfr
/usr/lib64/libmpfr.so
/usr/lib64/libmpfr.so.4
/usr/lib64/libmpfr.so.4.1.0

> locate mpfr.h
/usr/include/mpfr.h

> grep MPFR_VERSION /usr/include/mpfr.h
#define MPFR_VERSION_MAJOR 3
#define MPFR_VERSION_MINOR 1
#define MPFR_VERSION_PATCHLEVEL 0

You can download MPFR from https://www.mpfr.org.
