The following packages are required to build and use the library, and can probably be obtained from your favorite package manager:

• gsl (>= 1.15): http://www.gnu.org/software/gsl/
• C++ compiler with C++11 support.

This software is designed to work in POSIX environments with standard conformant C++ compilers. It should be noted that various C++11 features are used for efficient calculation, so a reasonably modern compiler is necessary. See the list below for compilers known to compile the software successfully.

• GCC: Version 4.8.1 or later is known to work.
• Clang: Version 3.3 or later is known to work.
• ICC: Version 15.0 is known to work; version 14.0 should work as well but has not been tested.

It is also necessary to have a sufficiently new standard library implementation. The libstdc++ supplied with gcc 4.8 or newer, and libc++ are known to work.

The software has been tested and found to work on the following operating systems:

• Linux
• Darwin (Mac OS X)
• FreeBSD

A configure script, configure, is provided in the root directory.

The path for the GSL libraries can be specified running:

./configure --with-gsl-incdir=DIR --with-gsl-libdir=DIR

if not specified pkg-config will be used to try to find the your GSL installation. After successful configuration run:

make

To verify that the software is functioning correctly, the unit tests can be run with the command:

make test

Finally, the software can be installed using the command:

make install

By default this will attempt to install the library within /usr/local; this can be changed by using the --prefix option when running configure:

./configure --prefix=$HOME

will select to install the software in the current user's home directory, for example.

Three examples programs can be found in the examples subdirectory.

In order to plot the example results you will need:

• gnuplot (>4.0): http://www.gnuplot.info/

Documentation can be generated by running:

make docs

and will be put in the docs subdirectory.
