NAME

       Alien::Build::Plugin::Build::Autoconf - Autoconf plugin for Alien::Build

VERSION

       version 2.84

SYNOPSIS

        use alienfile;
        plugin 'Build::Autoconf';

DESCRIPTION

       This plugin provides some tools for building projects that use autoconf.  The main thing this provides is
       a "configure" helper, documented below and the default build stage, which is:

        '%{configure} --disable-shared',
        '%{make}',
        '%{make} install',

       On Windows, this plugin also pulls in the Alien::Build::Plugin::Build::MSYS which is required for
       autoconf style projects on windows.

       The other thing that this plugin does is that it does a double staged "DESTDIR" install.  The author has
       found this improves the overall reliability of Alien modules that are based on autoconf packages.

       This plugin supports out-of-source builds (known in autoconf terms as "VPATH" builds) via the meta
       property "out_of_source".

       NOTE: by itself, this plugin is only intended for use on packages that include a "configure" script.  For
       packages that expect you to use Autotools to generate a configure script before building, you can use
       Alien::Autotools to generate the "configure" script and use this plugin to run it.  For more details see
       the documentation for Alien::Autotools.

PROPERTIES

   with_pic
       Adds "--with-pic" option when running "configure".  If supported by your package, it will generate
       position independent code on platforms that support it.  This is required to XS modules, and generally
       what you want.

       autoconf normally ignores options that it does not understand, so it is usually a safe and reasonable
       default to include it.  A small number of projects look like they use autoconf, but are really an
       autoconf style interface with a different implementation.  They may fail if you try to provide it with
       options such as "--with-pic" that they do not recognize.  Such packages are the rationale for this
       property.

   msys_version
       The version of Alien::MSYS required if it is deemed necessary.  If Alien::MSYS isn't needed (if running
       under Unix, or MSYS2, for example) this will do nothing.

   config_site
       The content for the generated "config.site".

HELPERS

   configure
        %{configure}

       The correct incantation to start an autoconf style "configure" script on your platform.  Some reasonable
       default flags will be provided.

ENVIRONMENT

       "SITE_CONFIG"
           For  a  share  install, this plugin needs to alter the behavior of autotools using "site.config".  It
           does this by generating a "site.config" file on the fly, and setting  the  "SITE_CONFIG"  environment
           variable.   In  the event that you already have your own "SITE_CONFIG" set, that file will be sourced
           from the generated one, so your local defaults should still be honored, unless it is one  that  needs
           to be changed for a share install.

           In  particular,  the  "lib" directory must be overridden, because on some platforms dynamic libraries
           will otherwise be placed in directories that  Alien::Build  doesn't  normally  look  in.   Since  the
           alienized  package will be installed in a share directory, and not a system directory, that should be
           fine.

       "ALIEN_BUILD_SITE_CONFIG"
           If defined, this file will be also be sourced in the generated "site.config".   This  allows  you  to
           have local defaults for alien share installs only.
