Accessing VECLIB

 

When you use the –aarchive_sharedflag on your compiler command line for

 

HP-UX, it ensures that the compiler links the archive library. If the archive

 

library is not available, then it links the shared library. If you omit

 

–aarchive_sharedand –ashared_archive, the linker defaults to linking the

 

shared library. Link with –Bstaticon Linux systems.

 

If your program uses subprograms from VECLIB, LAPACK, ScaLAPACK,

 

Distributed SuperLU, SOLVERS and VMATH, specify −llapack, −lveclib,

 

−lscalapack, −lsuperlu_dist, −lsolvers, and −lvmath or −llapack8, −lveclib8,

 

−lscalapack8, −lsuperlu_dist8, −lsolvers8 and −lvmath8 on the compiler

 

command line.

 

 

 

NOTE

 

Do not mix subprograms from the two types of 64-bit address libraries

 

 

(those with 32-bit integers and those with 64-bit integers) in the same

 

 

program.

 

 

 

 

Each of the VECLIB and LAPACK library files is complete in itself, meaning

 

that you do not need to link one library because you have called subprograms

 

from another. This is because various subprograms are included in both

 

libraries. For example, VECLIB subroutine SGEMV is called by several

 

LAPACK subprograms, and therefore, is included in the LAPACK library. Thus,

 

in general, you have to link only the library or libraries you need.

For PA-Based Systems

1.To link a program that uses VECLIB for use on the same machine, use one of the following commands:

f90 [options] file ... –Wl,–aarchive_shared −lveclib

cc [options] file ... –Wl,–aarchive_shared −lveclib −lcl −lm

aCC [options] file ... –Wl,–aarchive_shared −lveclib −lcl −lm

2.Specify the entire path of the library file on the compiler command line that links your program. For example, to link your program with VECLIB for use with 32- or 64-bit addressing on a PA-based system, use one of the following:

f90 [options] file ... /opt/mlib/lib/[pa2.0pa20_64]/libveclib.a

cc [options] file ... /opt/mlib/lib/[pa2.0pa20_64]/libveclib.a −lcl −lm

aCC [options] file ... /opt/mlib/lib/[pa2.0pa20_64]/libveclib.a −lcl −lm

Replace libveclib.a with libveclib.sl on your compiler command line if you want to link the shared library on a PA-based system.

3.Use the −lveclib option on the compiler command line that links your program, preceded by:

−Wl,–aarchive_shared,−L/opt/mlib/lib/[pa2.0pa20_64]
