NAME ^

Alien::FLTK2 - Build and use the experimental 2.0.x branch Fast Light Toolkit

Description ^

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

Synopsis ^

    use Alien::FLTK2;
    use ExtUtils::CBuilder;
    my $AF     = Alien::FLTK2->new();
    my $CC     = ExtUtils::CBuilder->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('C++'                => 1,
                           source               => $source,
                           include_dirs         => [$AF->include_dirs()],
                           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::FLTK2 should create objects with the new constructor.

    my $AF = Alien::FLTK2->new( );

Methods ^

After creating a new Alien::FLTK2 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:

static

Returns flags to link against a static FLTK library.

FLTK's license allows static linking, but Alien::FLTK2 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).

branch

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

Returns the SVN branch of the source Alien::FLTK2 was built with. For the 1.3.x branch of fltk, see Alien::FLTK.

revision

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

Returns the SVN revision number of the source Alien::FLTK2 was built with.

capabilities

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

Returns a list of capabilities supported by your Alien::FLTK2 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::FLTK2 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 XCurser 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
