Module::Build::Pluggable::Fortran - Plugin for Module::Build to compile Fortran .f files

VERSION

version 0.27

SYNOPSIS

# Build.PL
use strict;
use warnings;
use Module::Build::Pluggable ('Fortran');

my $builder = Module::Build::Pluggable->new(
    dist_name  => 'PDL::My::Module',
    license    => 'perl',
    f_source   => [ 'src' ],
    requires   => { },
    configure_requires => {
        'Module::Build'                      => '0.4004',
        'Module::Build::Pluggable'           => '0',
        'Module::Build::Pluggable::Fortran'  => '0.20',
    },

);
$builder->create_build_script();

DESCRIPTION

This is a plugin for Module::Build (using Module::Build::Pluggable) that will assist in building distributions that require Fortran .f files to be compiled. Please see the Module::Build::Authoring documentation if you are not familiar with it.

Add Prerequisites

build_requires => {
    'ExtUtils::F77'      => '0',
    'ExtUtils::CBuilder' => '0.23',
},

You can, or course, require your own versions of these modules by adding them to requires = {}> as usual.

Compile .f files

The directories specified by the f_source array within your distribution will be searched for .f files which are, immediately prior to the build phase, compiled into .o files. This is accomplished (effectively) by running:

my $mycompiler = ExtUtils::F77->compiler();
my $mycflags   = ExtUtils::F77->cflags();
system( "$mycompiler -c -o $file.o $mycflags -O3 -fPIC $file.f" );

Add Extra Linker Flags

extra_linker_flags =>  $PDL::Config{MALLOCDBG}->{libs}
  if $PDL::Config{MALLOCDBG}->{libs};
extra_linker_flags => ExtUtils::F77->runtime, <your fortran object files>

Adds the linker flags from ExtUtils::F77 and all the .o object files created from the .f Fortran files.
