NAME

Alien::FLTK - Build and use the stable 1.3.x branch of the Fast Light Toolkit

Description

This distribution builds and installs libraries for the (stable) 1.3.x branch of the FLTK GUI toolkit.

Synopsis

use Alien::FLTK;
use ExtUtils::CBuilder;
my $AF  = Alien::FLTK->new();
my $CC  = ExtUtils::CBuilder->new();
my $SRC = 'hello_world.cxx';
open(my $FH, '>', $SRC) || die '...';
syswrite($FH, <<'') || die '...'; close $FH;
  #include <FL/Fl.H>
  #include <FL/Fl_Window.H>
  #include <FL/Fl_Box.H>
  int main(int argc, char **argv) {
    Fl_Window *window = new Fl_Window(300,180);
    Fl_Box *box = new Fl_Box(FL_UP_BOX, 20, 40, 260, 100, "Hello, World!");
    box->labelfont(FL_BOLD + FL_ITALIC);
    box->labelsize(36);
    box->labeltype(FL_SHADOW_LABEL);
    window->end();
    window->show(argc, argv);
    return Fl::run();
}

my $OBJ = $CC->compile('C++'                => 1,
                       source               => $SRC,
                       include_dirs         => [$AF->include_dirs()],
                       extra_compiler_flags => $AF->cxxflags()
);
my $EXE =
    $CC->link_executable(
     objects            => $OBJ,
     extra_linker_flags => '-L' . $AF->library_path . ' ' . $AF->ldflags()
    );
print system('./' . $EXE) ? 'Aww...' : 'Yay!';
END { unlink grep defined, $SRC, $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_dirs

my @include_dirs = $AF->include_dirs( );

Returns a list of the locations of the headers installed during the build process and those required for compilation.

library_path

my $lib_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:

• 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).

Notes

Requirements

Prerequisites differ by system...

• Win32

  The fltk 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
  

  Additionally, the optional XCursor lib may be installed with:

    > 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
