Beyond Linux® From Scratch (systemd Edition) - Version 11.2

Chapter 9. General Libraries

Gsl-2.7.1

Introduction to Gsl

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting.

This package is known to build and work properly using an LFS-11.2 platform.

Package Information

Gsl Dependencies

Optional

Sphinx with sphinx_rtd_theme

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/gsl

Installation of Gsl

Install Gsl by running the following commands: 

./configure --prefix=/usr --disable-static &&
make

If you have the optional Sphinx package installed, build the documentation with: 

make html

To test the results, issue: make check.

Now, as the root user: 

make install

If you built the documentation, install it (as root) with: 

mkdir                   /usr/share/doc/gsl-2.7.1 &&
cp -R doc/_build/html/* /usr/share/doc/gsl-2.7.1

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.
