| NAME | ||
| Alien::SDL2 - building, finding and using SDL2 binaries | ||
| VERSION | ||
| Version 0.002 | ||
| SYNOPSIS | ||
| Alien::SDL2 tries (in given order) during its installation: | ||
| * When given "--with-sdl2-config" option use specified sdl2-config | ||
| script to locate SDL2 libs. | ||
| perl Build.PL --with-sdl2-config=/opt/sdl2/bin/sdl2-config | ||
| or using default script name 'sdl2-config' by running: | ||
| perl Build.PL --with-sdl2-config | ||
| IMPORTANT NOTE: Using --with-sdl2-config avoids considering any | ||
| other build methods; no prompt with other available build options. | ||
| * Locate an already installed SDL2 via 'sdl2-config' script. | ||
| * Download prebuilt SDL2 binaries (if available for your platform). | ||
| * Build SDL2 binaries from source codes (if possible on your system). | ||
| Later you can use Alien::SDL2 in your module that needs to link agains | ||
| SDL2 and/or related libraries like this: | ||
| # Sample Makefile.pl | ||
| use ExtUtils::MakeMaker; | ||
| use Alien::SDL2; | ||
| WriteMakefile( | ||
| NAME => 'Any::SDL2::Module', | ||
| VERSION_FROM => 'lib/Any/SDL2/Module.pm', | ||
| LIBS => Alien::SDL2->config('libs', [-lAdd_Lib]), | ||
| INC => Alien::SDL2->config('cflags'), | ||
| # + additional params | ||
| ); | ||
| DESCRIPTION | ||
| Please see Alien for the manifesto of the Alien namespace. | ||
| In short "Alien::SDL2" can be used to detect and get configuration | ||
| settings from an installed SDL2 and related libraries. Based on your | ||
| platform it offers the possibility to download and install prebuilt | ||
| binaries or to build SDL2 & co. from source codes. | ||
| The important facts: | ||
| * The module does not modify in any way the already existing SDL2 | ||
| installation on your system. | ||
| * If you reinstall SDL2 libs on your system you do not need to | ||
| reinstall Alien::SDL2 (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 | ||
| automaticly loadable as they will be stored somewhere under perl | ||
| module's 'share' directory. To handle this scenario Alien::SDL2 | ||
| 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 'sdl2-config' script: | ||
| Alien::SDL2->config('prefix'); # gives the same string as 'sdl2-config --prefix' | ||
| Alien::SDL2->config('version'); # gives the same string as 'sdl2-config --version' | ||
| Alien::SDL2->config('libs'); # gives the same string as 'sdl2-config --libs' | ||
| Alien::SDL2->config('cflags'); # gives the same string as 'sdl2-config --cflags' | ||
| On top of that this function supports special parameters: | ||
| Alien::SDL2->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 SDL2 | ||
| libs. | ||
| Alien::SDL2->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 SDL2 libs. | ||
| Alien::SDL2->config('ld_shlib_map'); | ||
| Returns a reference to hash of value pairs '<libnick>' => | ||
| '<full_path_to_shlib'>, where '<libnick>' is shortname for SDL2 related | ||
| library like: SDL2, SDL2_gfx, SDL2_net, SDL2_sound ... + some non-SDL2 | ||
| shortnames e.g. smpeg, jpeg, png. | ||
| NOTE: config('ld_<something>') return an empty list/hash if you have | ||
| decided to use SDL2 libraries already installed on your system. This | ||
| concerns 'sdl2-config' detection. | ||
| check_header() | ||
| This function checks the availability of given header(s) when using | ||
| compiler options provided by "Alien::SDL2->config('cflags')". | ||
| Alien::SDL2->check_header('SDL2.h'); | ||
| Alien::SDL2->check_header('SDL2.h', 'SDL2_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 SDL2 prefix | ||
| direcotry and based on "#define" macros inside this header file tries to | ||
| get a version triplet. | ||
| Alien::SDL2->get_header_version('SDL_mixer.h'); | ||
| Alien::SDL2->get_header_version('SDL_version.h'); | ||
| Alien::SDL2->get_header_version('SDL2_gfxPrimitives.h'); | ||
| Alien::SDL2->get_header_version('SDL_image.h'); | ||
| Alien::SDL2->get_header_version('SDL_mixer.h'); | ||
| Alien::SDL2->get_header_version('SDL_net.h'); | ||
| Alien::SDL2->get_header_version('SDL_ttf.h'); | ||
| Alien::SDL2->get_header_version('smpeg.h'); | ||
| Returns string like '1.2.3' or undef if not able to find and parse | ||
| version info. | ||
| havelib() | ||
| Checks the presence of given SDL2 related libraries. | ||
| Alien::SDL2->havelib('SDL2'); | ||
| #or | ||
| Alien::SDL2->havelib('SDL2', 'SDL2_image', 'SDL2_mixer'); | ||
| Parameter(s): One or more SDL2 related lib names - e.g. SDL2, | ||
| SDL2_mixer, SDL2_image, ... | ||
| Returns: 1 if all libs specified as a param are available; 0 otherwise. | ||
