=head1 NAME
Alien::Build::Plugin::Build::Autoconf - Autoconf plugin for Alien::Build
=head1 VERSION
version 2.29
=head1 SYNOPSIS
use alienfile;
plugin 'Build::Autoconf';
=head1 DESCRIPTION
This plugin provides some tools for building projects that use autoconf. The main thing
this provides is a C<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 L<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 C<DESTDIR> install.
The author has found this improves the overall reliability of L<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 C<out_of_source>.
=head1 PROPERTIES
=head2 with_pic
Adds C<--with-pic> option when running C<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 C<--with-pic> that they do
not recognize. Such packages are the rationale for this property.
=head2 msys_version
The version of L<Alien::MSYS> required if it is deemed necessary. If L<Alien::MSYS>
isn't needed (if running under Unix, or MSYS2, for example) this will do nothing.
=head2 config_site
The content for the generated C<config.site>.
=head1 HELPERS
=head2 configure
%{configure}
The correct incantation to start an autoconf style C<configure> script on your platform.
Some reasonable default flags will be provided.
=head1 ENVIRONMENT
=over 4
=item C<ALIEN_BUILD_SITE_CONFIG>
This plugin needs to alter the behavior of autotools via the C<site.config> file and so sets
and possibly overrides any existing C<SITE_CONFIG>. Normally that is what you want but you
can also insert your own C<site.config> in addition by using this environment variable.
