DUB:创建两个具有共同代码库的可执行文件

Question

我需要生成两个具有一些通用源代码的 exe 文件。使用配音的最佳方法是什么？

我试过做 , 但收到有关仅允许使用一个主要功能的错误消息。

这是我的 dub.json:

{
    "name": "code1",
    "authors": [ "Suliman" ],
    "description": "A minimal D application.",
    "copyright": "Copyright © 2016, Suliman",
    "license": "proprietary",
    "subPackages": [
    {
        "name": "App1",
        "targetName": "App1",
        "description": "App1",
        "targetType": "executable",
        "excludedSourceFiles" : ["source/App2/*"],
        "excludedSourceFiles" : ["source/app2.d"]
    },

    {
        "name": "App2",
        "targetName": "App2",
        "description": "App2",
        "targetType": "executable",
        "excludedSourceFiles" : ["source/App1/*"],
        "excludedSourceFiles" : ["source/app1.d"]
    }]
}

你的 dub.json 可以工作，但你需要明确地告诉它构建一个 带有 dub build :App1 或 dub build :App2 的子包(其中 :App1 是一个 code1:App1 的快捷方式。

单独的配置在这里可能更合适:

"configurations": [
    {
        "name": "App1",
        "targetType": "executable",
        "mainSourceFile": "source/app1.d",
        "excludedSourceFiles": [ "source/app2.d", "source/App2/*" ],
        "targetName": "app1"
    },
    {
        "name": "App2",
        "targetType": "executable",
        "mainSourceFile": "source/app2.d",
        "excludedSourceFiles": [ "source/app1.d", "source/App1/*" ],
        "targetName": "app2"
    }
]

dub build --config=App1 将生成 app1， dub build --config=App2 将生成 app2

普通 dub build 将默认为 App1。

请注意，您需要 excludedSourceFiles，这样 dub 就不会看到重复的 main。

The docs反对 为此目的使用子包:

It is also possible to define the sub packages within the root package file, but note that it is generally discouraged to put the source code of multiple sub packages into the same source folder. Doing so can lead to hidden dependencies to sub packages that haven't been explicitly stated in the "dependencies" section. These hidden dependencies can then result in build errors in conjunction with certain build modes or dependency trees that may be hard to understand.

我发现你用的是dub.json，所以我把json格式放在上面。为了 引用，这是我之前发布的dub.sdl格式。

configuration "App1" {
    targetType "executable"
    mainSourceFile "source/app1.d"
    excludedSourceFiles "source/app2.d" "source/App2/*"
    targetName "app1"
}

configuration "App2" {
    targetType "executable"
    mainSourceFile "source/app2.d"
    excludedSourceFiles "source/app1.d" "source/App1/*"
    targetName "app2"
}
