This directory contains the AMUSE software. With AMUSE you can write scripts to simulate astrophysical problems in different domains.

The documentation and the software can be found at:

• http://www.amusecode.org

To build amuse you need a working build environment and install some prerequisites. This document contains the quick install instructions, if these fail please look at the detailed descriptions of the installation procedure in the documents in the 'doc/install' directory.

To build AMUSE from source you need to have a working build environment. The AMUSE build system needs a C++ and a 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"

In OS X you can install homebrew or macports package managers (both need the Apple Developer Tools). If you do not want to use any of these package managers you will need to install a fortran compiler as the Apple Developer Tools do not include a fortran compiler, you can find one at:

• http://hpc.sourceforge.net/

This document describes installation of the pre-requisite software packages to a user directory. If you have a recent Ubuntu or Fedora distribution you can follow the installation instructions in doc/install/howto-install-prerequisites.txt to install the packages as part of the system.

1. Make a prerequisite software directory (can be set to any directory)

   mkdir ~/amuse/prerequisites

2. Set the PREFIX, PATH and LD_LIBRARY_PATH environement variables

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

   2b. If you have ifort and/or icc, or if you encounter problems with NetCDF (optional dependency) you may need to set also:

    ```bash
    export LIBRARY_PATH=${PREFIX}/lib:${LIBRARY_PATH}
    export CPATH=${PREFIX}/include:${CPATH}
    ```
   

3. Download and install python

   cd doc/install
   ./install-python.sh

4. Download and install the other pre-requisites (script is also in the doc/install directory)

   ./install.py install

You can set the the PREFIX, PATH and LD_LIBRARY_PATH environment variables in you bashrc file. Please make sure the ${PREFIX}/bin directory is first in the path.

In bash, you can extend your .bashrc file with:

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

All modules can be build with a configure and make command. Start make from the main amuse directory (directory this README file lives in). The main task of the configure script is to check if the prerequisite packages have been installed.

1. Configure the source code

   ./configure

2. Build the code with make

   make

AMUSE comes with a large set of tests, most can be run automatically. To run these tests start the nosetests command from the main amuse directory (directory this README file lives in).

To run these tests do:

1. Run the automatic tests

nosetests -v
