For my (very) early stage GtkD program, my SCons script (using "all source at once") generates a 6MB executable that works. Dub appears to think that it is creating a .a archive and create 142MB of it. So how to create an executable with Dub?

You need to add a package.json file to your project.

I accidentally sent the above message too soon.

You either need to explicitly set the target type[1] to "executable" or make sure your project works with "autodetect". Add the GtkD package as a dependency[2].

I statically build GtkD application using dub and it gives me binary about 14 Mb in debug mode and stripped binary is about 8 or 6 Mb. But I built GtkD separately and link against it using the following package.json:

{
    "name": "renderer",
    "targetType": "library",
    "versions": [
        "Derelict3",
        "gl3n",
        ],
    "libs": [
        "gtkd-2",
        "gtkdgl-2",
        "dl",
        "DerelictGL3",
        "DerelictUtil",
        "DerelictFI",
        "gl3n",
        "glamour",
        "curl",
    ],
    "importPaths": [
        "~/.dub/packages/gtk-d-master/src",
        "~/.dub/packages/gtk-d-master/srcgl",
        "~/.dub/packages/derelict-gl3-master/source",
        "~/.dub/packages/derelict-fi-master/source",
        "~/.dub/packages/derelict-util-1.0.0/source",
        "~/.dub/packages/gl3n-master/",
        "~/.dub/packages/glamour/",
    ],
    "configurations": [
        {
            "name": "test",
            "targetType": "executable",
            "sourcePaths": ["test"],
        }
    ]
}

So it's a hack, but it works for me - I have fast compilation at least.
I did the following - fetched packages I need, built every package using dub and copied libs to /usr/local/lib - probably it's better to use path to libs instead of copying.

I was worried by that previous post as I think it impossible to have a Dub build without a package.json ;-)

It seems that a project with no target type but just a dependency on GtkD generates static library rather than executable. I'll use an explicit setting to avoid autodetect.

Thanks.
