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 2013.

GMP:

The multi-field persistent homology algorithm requires GMP which is a free library for arbitrary-precision arithmetic, operating on signed integers, rational numbers, and floating point numbers.

The following example requires the GNU Multiple Precision Arithmetic Library (GMP) and will not be built if GMP is not installed:

Persistent_cohomology/rips_multifield_persistence Having GMP version 4.2 or higher installed is recommended.

CGAL:

CGAL is a C++ library which provides easy access to efficient and reliable geometric algorithms.

The following examples require the Computational Geometry Algorithms Library (CGAL) and will not be built if CGAL is not installed:

GudhUI
Persistent_cohomology/alpha_shapes_persistence
Simplex_tree/simplex_tree_from_alpha_shapes_3

Having CGAL version 4.4 or higher installed is recommended. The procedure to install this library according to your operating system is detailed here http://doc.cgal.org/latest/Manual/installation.html
