How to Use the GNU Scientific Library (GSL) on ATS-Hosted Clusters

Installed location:

• GSL is installed in: /u/local/apps/gsl/current.

How to run GSL from a C program

In your program include the appropriate GSL header files as follows:

#include <gsl/gsl_include.h>

Replace gsl_include.h with the name of a GSL header file. Call the GSL functions.

To compile and link enter:

CC pgm.c -I$GSL_HOME/include -L$GSL_HOME/lib -lgsl -lgslcblas -lm [-static] -o pgm

Replace CC with either gcc or icc depending on which compiler you want to use. Replace pgm.c with the name of the file containing your source code and pgm with the name of the executable to be created. If you omit -static, you will have to set the LD_LIBRARY_PATH environment variable at run time to include $GSL_HOME/lib.

Either set environment variable GSL_HOME to /u/local/apps/gsl/current or replace $GSL_HOME with /u/local/apps/gsl/current in the command shown above.

How to run GSL from a Fortran program

GSL is not available from Fortran.
