NAME¶
Alien::SDL - building, finding and using SDL binaries
VERSION¶
Version 1.444
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'.
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.
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.
