NAME

       Alien::SDL - building, finding and using SDL binaries

VERSION

       Version 1.446

SYNOPSIS

       Alien::SDL tries (in given order) during its installation:

       •   When given "--with-sdl-config" option use specified sdl-config script to locate SDL
           libs.

            perl Build.PL --with-sdl-config=/opt/sdl/bin/sdl-config

           or using default script name 'sdl-config' by running:

            perl Build.PL --with-sdl-config

           IMPORTANT NOTE: Using --with-sdl-config avoids considering any other build methods; no
           prompt with other available build options.

       •   Locate an already installed SDL via 'sdl-config' script.

       •   Check for SDL libs in directory specified by SDL_INST_DIR variable.  In this case the
           module performs SDL library detection via '$SDL_INST_DIR/bin/sdl-config' script.

            SDL_INST_DIR=/opt/sdl perl ./Build.PL

       •   Download prebuilt SDL binaries (if available for your platform).

       •   Build SDL binaries from source codes (if possible on your system).

       Later you can use Alien::SDL in your module that needs to link agains SDL and/or related
       libraries like this:

           # Sample Makefile.pl
           use ExtUtils::MakeMaker;
           use Alien::SDL;

           WriteMakefile(
             NAME         => 'Any::SDL::Module',
             VERSION_FROM => 'lib/Any/SDL/Module.pm',
             LIBS         => Alien::SDL->config('libs', [-lAdd_Lib]),
             INC          => Alien::SDL->config('cflags'),
             # + additional params
           );

DESCRIPTION

       Please see Alien for the manifesto of the Alien namespace.

       In short "Alien::SDL" can be used to detect and get configuration settings from an
       installed SDL and related libraries.  Based on your platform it offers the possibility to
       download and install prebuilt binaries or to build SDL & co. from source codes.

       The important facts:

       •   The module does not modify in any way the already existing SDL installation on your
           system.

       •   If you reinstall SDL libs on your system you do not need to reinstall Alien::SDL
           (providing that you use the same directory for the new installation).

       •   The prebuild binaries and/or binaries built from sources are always installed into
           perl module's 'share' directory.

       •   If you use prebuild binaries and/or binaries built from sources it happens that some
           of the dynamic libraries (*.so, *.dll) will not be automatically loadable as they will
           be stored somewhere under perl module's 'share' directory. To handle this scenario
           Alien::SDL offers some special functionality (see below).

METHODS

   config()
       This function is the main public interface to this module. Basic functionality works in a
       very similar maner to 'sdl-config' script:

           Alien::SDL->config('prefix');   # gives the same string as 'sdl-config --prefix'
           Alien::SDL->config('version');  # gives the same string as 'sdl-config --version'
           Alien::SDL->config('libs');     # gives the same string as 'sdl-config --libs'
           Alien::SDL->config('cflags');   # gives the same string as 'sdl-config --cflags'

       On top of that this function supports special parameters:

           Alien::SDL->config('ld_shared_libs');

       Returns a list of full paths to shared libraries (*.so, *.dll) that will be required for
       running the resulting binaries you have linked with SDL libs.

           Alien::SDL->config('ld_paths');

       Returns a list of full paths to directories with shared libraries (*.so, *.dll) that will
       be required for running the resulting binaries you have linked with SDL libs.

           Alien::SDL->config('ld_shlib_map');

       Returns a reference to hash of value pairs '<libnick>' => '<full_path_to_shlib'>, where
       '<libnick>' is shortname for SDL related library like: SDL, SDL_gfx, SDL_net, SDL_sound
       ... + some non-SDL shortnames e.g. smpeg, jpeg, png.

       NOTE: config('ld_<something>') return an empty list/hash if you have decided to use SDL
       libraries already installed on your system. This concerns 'sdl-config' detection and
       detection via '$SDL_INST_DIR/bin/sdl-config'.

   check_header()
       This function checks the availability of given header(s) when using compiler options
       provided by "Alien::SDL->config('cflags')".

           Alien::SDL->check_header('SDL.h');
           Alien::SDL->check_header('SDL.h', 'SDL_net.h');

       Returns 1 if all given headers are available, 0 otherwise.

   get_header_version()
       Tries to find a header file specified as a param in SDL prefix direcotry and based on
       "#define" macros inside this header file tries to get a version triplet.

           Alien::SDL->get_header_version('SDL_mixer.h');
           Alien::SDL->get_header_version('SDL_version.h');
           Alien::SDL->get_header_version('SDL_gfxPrimitives.h');
           Alien::SDL->get_header_version('SDL_image.h');
           Alien::SDL->get_header_version('SDL_mixer.h');
           Alien::SDL->get_header_version('SDL_net.h');
           Alien::SDL->get_header_version('SDL_ttf.h');
           Alien::SDL->get_header_version('smpeg.h');

       Returns string like '1.2.3' or undef if not able to find and parse version info.
