NAME
ExtUtils::F77 - Simple interface to F77 libs
DESCRIPTION
This module tries to figure out how to link C programs
with Fortran subroutines on your system. Basically one
must add a list of Fortran runtime libraries. The problem
is their location and name varies with each OS/compiler
combination!
This module tries to implement a simple 'rule-of-thumb'
database for various flavours of UNIX systems. A simple
self-documenting Perl database of knowledge/code for fig
uring out how to link for various combinations of OS and
compiler is embedded in the modules Perl code. Please help
save the world by sending database entries for your system
to kgb@aaoepp.aao.gov.au
- The library list which the module returns can be explic
itly overridden by setting the environment variable
F77LIBS, e.g. - % setenv F77LIBS "-lfoo -lbar"
% perl Makefile.PL

SYNOPSIS
use ExtUtils::F77; # Automatic guess use ExtUtils::F77 qw(sunos); # Specify system use ExtUtils::F77 qw(linux g77); # Specify system and compiler $fortranlibs = ExtUtils::F77->runtime;
METHODS
The following methods are provided:
- · runtime
- Returns a list of F77 runtime libraries.
$fortranlibs = ExtUtils::F77->runtime; - · runtimeok
Returns TRUE only if runtime libraries have been found
successfully. - · trail_
Returns true if F77 names have trailing underscores.
- · compiler
Returns command to execute the compiler (e.g. 'f77').
- · cflags
Returns compiler flags.
- · testcompiler
Test to see if compiler actually works.
- More methods will probably be added in the future.
