This section contains information on setting up the dependencies for Hyperion as well as Hyperion itself. If you have any issues with the installation of any of the dependencies or Hyperion, please first talk to your system administrator to see if they can help you get set up!

The easy way

The easiest way to install Hyperion and all the dependencies on MacOS X or Linux is to use the Anaconda Python Distribution or Miniconda. Once you have either of these set up, you can install Hyperion by simply doing:

conda install -c conda-forge hyperion

This will install both the Fortran binaries and the Python library for Hyperion (as well as all the dependencies including MPI and HDF5). That’s it! You can check that the installation works by making sure that the following commands do not return ‘command not found’:

$ hyperion
usage: hyperion [-h] [-f] [-m n_cores] input output
hyperion: error: the following arguments are required: input, output
$ hyperion_car
Usage: hyperion_car [-f] input_file output_file

If you see the same as the above, you are all set!

The longer way


Once you have installed the dependencies as described in one of the sections above, you are ready to install Hyperion!

Download the latest tar file from here, then expand it with:

tar xvzf Hyperion-x.x.x.tar.gz
cd Hyperion-x.x.x

Python module

Install the Python module with:

python install


python install --user

if you do not have root access. Check that the module installed correctly:

$ python
Python 2.7.2 (default, Jan 31 2012, 22:38:06)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import hyperion

and also try typing:

$ hyperion

in your shell. If you get command not found, you need to ensure that the scripts installed by Python are in your $PATH. If you do not know where these are located, check the last line of the install command above, which should contain something like this:

changing mode of /Users/tom/Library/Python/2.7/bin/hyperion to 755

The path listed (excluding hyperion at the end) should be in your $PATH. On Linux systems, this path will often be $HOME/.local/bin.


On recent versions of MacOS X, you may encounter the following error when trying to install the Python library for Hyperion:

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

If this is the case, try setting the following environment variables before installing it:

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

Fortran binaries

Compile the Fortran code with:

make install

By default, the binaries will be written to /usr/local/bin (which will require you to use sudo for the last command). If you would prefer to install to your home directory, you can change this using the --prefix option to configure, for example:

./configure --prefix=$HOME/usr

To check that the Fortran binaries are correctly installed, try typing:

$ hyperion_sph
Usage: hyperion input_file output_file

If you get:

$ hyperion_sph
hyperion_sph: command not found

then something went wrong in the installation, or the directory to which you installed the binaries is not in your $PATH. Otherwise, you are all set!

CMake build system

An experimental build system for the Fortran binaries based on CMake is now available. You can find the detailed instructions on how to use it at the page Alternative CMake build system.
