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 figuring 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 karl_pgplot@mac.com
The library list which the module returns can be explicitly 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:
o runtime
Returns a list of F77 runtime libraries.
$fortranlibs = ExtUtils::F77->runtime;
o runtimeok
Returns TRUE only if runtime libraries have been found successfully.
o trail_
Returns true if F77 names have trailing underscores.
o compiler
Returns command to execute the compiler (e.g. 'f77').
o cflags
Returns compiler flags.
o testcompiler
Test to see if compiler actually works.
More methods will probably be added in the future.
