NAME

Alien::GMP - Alien package for the GNU Multiple Precision library.

SYNOPSIS

In your Build.PL:

use Module::Build;
use Alien::GMP;
my $builder = Module::Build->new(
  ...
  configure_requires => {
    'Alien::GMP' => '0',
    ...
  },
  extra_compiler_flags => Alien::GMP->cflags,
  extra_linker_flags   => Alien::GMP->libs,
  ...
);

$build->create_build_script;

In your Makefile.PL:

use ExtUtils::MakeMaker;
use Config;
use Alien::GMP;

WriteMakefile(
  ...
  CONFIGURE_REQUIRES => {
    'Alien::GMP' => '0',
  },
  CCFLAGS => Alien::GMP->cflags . " $Config{ccflags}",
  LIBS    => [ Alien::GMP->libs ],
  ...
);

DESCRIPTION

This distribution installs GMP so that it can be used by other Perl distributions. If already installed for your operating system, and it can be found, this distribution will use the GMP that comes with your operating system, otherwise it will download it from the Internet, build and install it for you.

C++ support

This Alien will provide the C++ bindings for GMP (libgmpxx) if possible. If you do not have a C++ compiler, or if your operating system vendor provides a GMP package without the needed C++ files then it will not be available. To use the C++ bindings, you can use the alt method to create a C++ instance of this GMP Alien. For example:

use ExtUtils::MakeMaker;
use Config;
use Alien::GMP;

WriteMakefile(
  ...
  CONFIGURE_REQUIRES => {
    'Alien::GMP' => '1.06', # require version that provides C++ bindings
  },
  CCFLAGS => Alien::GMP->alt('gmpxx')->cflags . " $Config{ccflags}",
  LIBS    => [ Alien::GMP->alt('gmpxx')->libs ],
  ...
);

Inline support

This module supports Inline's with functionality.
