NAME

Alien::FLTK - Build and use the Fast Light Toolkit binaries

Description

This distribution builds and installs libraries for the (experimental) 2.0.x branch of the FLTK GUI toolkit.

Synopsis

use Alien::FLTK;
use ExtUtils::CBuilder;
my $CC     = ExtUtils::CBuilder->new();
my $AF     = Alien::FLTK->new();
my $source = 'hello_world.cxx';
open(my $FH, '>', $source) || die '...';
syswrite($FH, <<'') || die '...'; close $FH;
  #include <fltk/Window.h>
  #include <fltk/Widget.h>
  #include <fltk/run.h>
  using namespace fltk;
  int main(int argc, char **argv) {
    Window *window = new Window(300, 180);
    window->begin();
    Widget *box = new Widget(20, 40, 260, 100, "Hello, World!");
    box->box(UP_BOX);
    box->labelfont(HELVETICA_BOLD_ITALIC);
    box->labelsize(36);
    box->labeltype(SHADOW_LABEL);
    window->end();
    window->show(argc, argv);
    return run();
  }

my $obj = $CC->compile(source               => $source,
                       extra_compiler_flags => $AF->cxxflags());
my $exe = $CC->link_executable(
                              objects            => $obj,
                              extra_linker_flags => $AF->ldflags()
);
print system('./' . $exe) ? 'Aww...' : 'Yay!';
END { unlink grep defined, $source, $obj, $exe; }

Constructor

There are no per-object configuration options as of this version, but there may be in the future, so any new code using Alien::FLTK should create objects with the new constructor.

my $AF = Alien::FLTK->new( );

Methods

After creating a new Alien::FLTK object, use the following methods to gather information:

include_path

my $include_path = $AF->include_path( );

Returns the location of the headers installed during the build process.

library_path

my $include_path = $AF->library_path( );

Returns the location of the private libraries we made and installed during the build process.

cflags

my $cflags = $AF->cflags( );

Returns additional C compiler flags to be used.

cxxflags

my $cxxflags = $AF->cxxflags( );

Returns additional flags to be used to when compiling C++ using FLTK.

ldflags

my $ldflags = $AF->ldflags( qw[gl images] );

Returns additional linker flags to be used. This method can automatically add appropriate flags based on how you plan on linking to fltk. Acceptable arguments are:

static

Returns flags to link against a static FLTK library.

FLTK's license allows static linking, but Alien::FLTK does not build static libs. ...yet.

gl

Include flags to use GL.

This is an experimental option. Depending on your system, this may also include OpenGL or MesaGL.

images

Include flags to use extra image formats (PNG, JPEG).

revision

my $revision = $AF->revision( );

Returns the SVN revision number of the source Alien::FLTK was built with.

capabilities

my $caps = $AF->capabilities( );

Returns a list of capabilities supported by your Alien::FLTK installation. This list can be handed directly to ldflags( ).

config

my $configuration = $AF->config( );

Returns a hashref containing the raw configuration data collected during build. This would be helpful when reporting bugs, etc.

Notes

Requirements

Prerequisites differ by system...

Win32

The fltk2 libs and Alien::FLTK both build right out of the box with MinGW. Further testing is needed for other setups.

X11/*nix

X11-based systems require several development packages. On Debian, these may be installed with...

> sudo apt-get install libx11-dev
> sudo apt-get install libxi-dev
> sudo apt-get install libxcursor-dev
Darwin/OSX

Uh, yeah, I have no idea.

Installation

The distribution is based on Module::Build, so use the following procedure:

> perl Build.PL
> ./Build
> ./Build test
> ./Build install
