Beyond Linux® From Scratch (systemd Edition) - Version r12.0-816

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.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

Gsl Dependencies

Optional

sphinx_rtd_theme-1.3.0

Installation of Gsl

Install Gsl by running the following commands: 

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

If you have sphinx_rtd_theme-1.3.0 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.
