# Math::GSL
Math::GSL is a Perl interface to the [GNU Scientific Library](http://www.gnu.org/software/gsl/), using [SWIG](http://swig.org). The GNU
Scientific Library (GSL) is a numerical library for C and C++ programmers. It
is free software under the GNU General Public License. Math::GSL uses SWIG to
generate Perl bindings to *most* GSL functionality.
[](http://travis-ci.org/leto/math--gsl)
# Dependencies
Currently `Math::GSL` requires at least Perl 5.8.1 to compile.
## Library dependencies
- GSL version 1.15 or larger. If you have installed GSL on your system,
the location of the library files are determined by running the
`gsl-config` binary. If it cannot be found
in your `PATH`, [PkgConfig](http://metacpan.org/release/PkgConfig/) is
tried to locate GSL.
- If you have not installed GSL on your system,
[`Alien::GSL`](https://metacpan.org/pod/Alien::GSL) is used to
install the latest version on your system. `Alien::GSL` depends
on [`Net::SSLeay`](https://metacpan.org/pod/Net::SSLeay) to download
the library, which requires that you have
installed `libssl-dev` and `libz-dev` (on Debian platforms, or similar
libraries on other platforms).
# Installation
To install this module, run
```
cpanm Math::GSL
```
or download the tarball distribution
from [metacpan.org](https://metacpan.org/pod/Math::GSL) and run the following
commands:
perl Build.PL
./Build
./Build test
./Build install clean
# Support
After installing, you can find documentation for this module with the
perldoc command.
perldoc Math::GSL

# Developer information
## Git repo dependencies
SWIG >= 2.x is needed to build `Math::GSL` from the git repo, version
2.0.8 or newer is required to work with Perl 5.20 and
higher. SWIG 3.x is recommended.
On OS X with Homebrew, you can install swig with:
brew install swig
