Quick Install Guide

TOP uses the standard autotools (autoconf, automake) install procedure, you should be able to install it using:

# get the code:
git clone

# enter the source code directory:
cd top

# download the optional dependencies:
git submodule init
git submodule update

# prepare the configure script:

# configure and install TOP:
./configure && make install

You can get more details and options reading the following sections: getting the code, configure and compile and install.

Getting the code

From the git repository

The best way to get the latest version of the code is to download it from the repository:

# with ssh:
git clone

# with https:
git clone

This will download the latest version of the code in a directory named top. Enter this directory:

cd top

You can optionally download the parser to write oscillation equations with the new equation format:

git submodule init
git submodule update

Run the bootstrap script that will create the configure script:



In order to run the bootstrap script you will need to have autoconf (>=2.59), automake (>=1.9) and libtool installed.

You can then proceed to the configure steps.

From a source archive

Download a source archive from the download page.

If you don’t need the latest version of TOP, you can use a source archive. Extract your source archive and enter to source directory:

tar xvjz top-x.y.tar.bz2
cd top-x.y

And proceed to the configure steps.



The configure script allows you to configure the build environment of TOP. In order to install TOP, you will need:

  • a Fortran compiler supporting procedure interface (gfortran (>=4.9))
  • a recent version of Python (python (>=2.7))
  • the program f2py, usually shipped with numpy
  • the following python modules: numpy and h5py

Configure will try to detect the libraries installed in your system, if it fails to find both a BLAS and a LAPACK library it will return an error. You can try to re-run configure with some of the following option to help it find you libraries:

Configure options:

  • FC: allows you to choose your Fortran compiler (e.g. FC=gfortran)
  • LDFLAGS: sets linker flags. This can be used to specify libraries search directory (e.g. LDFLAGS=-L$HOME/local/lib)
  • LIBS: what libraries should be linked with TOP. (e.g. LIBS=-ltatlas)
  • CPPFLAGS: preprocessor flags, this can be used to tell the compiler where to find header files (e.g. CPPFLAGS=-I$HOME/local/include)
  • PYTHON: the python interpreter to use (e.g. PYTHON=python3)
  • --prefix=: this option allows you to set TOP’s install directory (by default the prefix is set to $HOME/local)


If you want to use Intel compiler (ifort) and the ATLAS library (installed in $HOME/local/lib), you want to configure with the following command line:

./configure FC=ifort LDFLAGS=-L$HOME/local/lib LIBS=-ltatlas

Compile & Install

After running successfully the configure script, you can compile and install TOP by running:

make install

TOP is composed of a compiler wrapper top-build installed in $prefix/bin, a few libraries installed in $prefix/lib and a python module installed in $prefix/lib/python-version/site-packages/top.

As few examples are also availiable in $prefix/share/top/models


You can source the shell script created in the directory where you compiled TOP to set up the environment variables PATH, LD_LIBRARY_PATH and PYTHONPATH with the path where TOP was installed.

Check you Install

See usage.

Using libester

In order to use ESTER stellar models, TOP needs to find where ESTER was installed on your system. In order to tell TOP’s configure script where to find libester, you need to provide it with the options: LDFLAGS=-L$PATH_TO_ESTER/lib and CPPFLAGS=-I$PATH_TO_ESTER/include.

For instance if ESTER was installed in $HOME/local, TOP should be able to find it if you configure with:

./configure LDFLAGS=-L$HOME/local/lib CPPFLAGS=-I$HOME/local/include
