Hi,

I recently started using dub, and I've reviewed some recent posts about using subpackages, but I didn't found a solution.

I've created a really simple project following the documentation for building multiple components, in fact I replicated the sample, but I'm getting always the same error:

Error executing command run: Main package must have a binary target type, not none. Cannot build.

I've tested with stable version and with master version of dub, same error on both.

What I'm trying to do is building a library in component1 and an executable in component2 using component1 as a dependency, and build everything from mylib directory.

Am I missing something or maybe I didn't understood how subpackages should work?

main dub.json:

{
        "name": "mylib",
        "description": "A minimal D application.",
        "copyright": "Copyright © 2014, rgaitan",
        "authors": ["rgaitan"],
        "targetType": "none",
        "dependencies": {
                "mylib:component1": "*",
                "mylib:component2": "*"
        },
        "subPackages": [
                "./component1/",
                "./component2/"
        ]
}

component1 dub.json:

{
        "name": "component1",
        "description": "A minimal D application.",
        "copyright": "Copyright © 2014, rgaitan",
        "authors": ["rgaitan"],
        "targetType": "library",
        "dependencies": {
        }
}

component2 dub.json:

{
        "name": "component2",
        "description": "A minimal D application.",
        "copyright": "Copyright © 2014, rgaitan",
        "authors": ["rgaitan"],
        "targetType": "executable",
        "dependencies": {
                "mylib:component1": "*"
        }
}

Thank you,

Rafa.

There is an enhancement request for supporting direct builds of this kind of package structure (#97), but until then, the explicit sub package needs to be specified like this:

dub build mylib:component2

or shorter (current beta version of DUB 0.9.22):

dub build :component2
