ARCHIVED: Link the ARPACK numerical library to your Fortran program on Karst at IU

ARPACK is a collection of Fortran 77 subroutines for solving large eigenvalue problems. For more, see the ARPACK Users' Guide. Following are instructions for linking the ARPACK library to your Fortran program on Karst at Indiana University.

1. Add the ARPACK library to your user environment:
   1. Make sure the Intel Compiler Suite module is loaded. To check, on the command line, enter module list, and review the output. If the intel/[version] module is not listed, add it with the module load command; on the command line, enter:

      module load intel
      

   2. Load the ARPACK module; on the command line, enter:

      module load arpack
      
2. To link the ARPACK library to your Fortran program, add the -L and -l options to your compile command as shown in the following example. The -L option adds the specified directory path to the library search list and should be placed before the -l option to which it applies.

   To compile myprogram.f and link it with the ARPACK library, on the command line, enter:

   ifort myprogram.f -L/N/soft/rhel6/2.1/lib -larpack -o myprogram
