Installation
############
Compiling
*********
The library uses c++11 and requires `Boost `_ with version
1.48.0 or more recent. It is a multi-platform library and compiles on Linux,
Mac OSX and Visual Studio 2015.
It also requires cmake to generate makefiles, and cython to compile the
library.
Demos and examples
==================
To build the demos and examples, run the following commands in a terminal:
.. code-block:: bash
cd /path-to-gudhi/
mkdir build
cd build/
cmake ..
make cython
A list of examples is available here.
Test suites
===========
To test your build, `py.test `_ is required. Run the
following command in a terminal:
.. code-block:: bash
cd /path-to-gudhi/build/src/cython
# For windows, you have to set PYTHONPATH environment variable
export PYTHONPATH='$PYTHONPATH:/path-to-gudhi/build/src/cython'
py.test
Documentation
=============
To build the documentation, `sphinx-doc `_ is
required. Please refer to *conf.py* file to see which
`sphinx-doc `_ modules are required to
generate the documentation. Run the following commands in a terminal:
.. code-block:: bash
make sphynx

CGAL
====
The :doc:`Alpha complex ` data structure and
:doc:`Tangential complex ` data structures,
:doc:`Bottleneck distance ` requires CGAL, which is a
C++ library which provides easy access to efficient and reliable geometric
algorithms.
Having CGAL version 4.7.0 or higher installed is recommended. The procedure to
install this library according to your operating system is detailed
`here `_.
The following examples require the Computational Geometry Algorithms Library:
