GNU Scientific Library

GNU Scientific Library also known as GSL is installed on the department's linux computers.

Where are the GSL Libraries?

In /usr/lib/ with most other systems libs (which is in the 'standard' search path for libraries).

What do I include at the top of a file of C code to make use of the GSL Libraries?

In your c code you need to #include the relevant headers, which would to be along the lines of:

  #include <gsl/gsl_math.h>

and then when compiling tell gcc to 'link' in the gsl library, with e.g.

  gcc -o app app.c -lgsl

and of course any extra options or libraries it may need.

How do I find out more about using GSL?

The online gsl manual can be viewed by running:

  info gsl

The GSL webpage is at http://www.gnu.org/software/gsl/.

What version of GSL has damtp got installed?

To query which version of GSL is installed at any time you can use the rpm command as in:

  rpm -q --queryformat '%{NAME}-%{VERSION}-%{RELEASE}: %{SUMMARY}\n' gsl gsl-devel
