将Scala库转换为DLL（.NET） [英] Converting a Scala library to a DLL (.NET)

问题描述

我正在尝试从scala类中创建一个Dll。我正在使用IntelliJ和SBT。我已经找到了一种使用ikvm转换器将.jar文件转换为Dll的方法。现在的问题：当我使用SBT下的软件包从.scala文件创建一个.jar文件，并尝试将其转换为ikvmc到Dll中，当集成到C＃中时，生成的库为空...

例如，转换Jama-Library（以Java编写）可以正常工作，转换Scama（以Scala编写）不起作用。

有没有办法将scala代码转换成d​​ll？有没有Scala to Java转换工具？

最好的问候，
Christoph

解决方案

我不了解.NET，但从SK-logic和您的意见来判断问题： sbt package does 不包括Scala运行时库，因为它假定您要将项目导出为要在其他Scala项目中使用的库。

因此，您将需要创建一个包含运行时的胖jar。例如，在此博客您可以通过转换项目jar和运行时jar来了解作者如何创建完全独立的可执行文件。

有不同的工具可以做到这一点SBT。最简单的是 sbt-assembly ，但是最终会出现一个非常大的文件，因为它只是添加了整个运行时。如果这是一个问题，您可能需要使用 proguard插件。有关此主题的更多信息，请参阅另一个StackOverflow条目。

I'm trying to create a Dll out of a scala-class. I'm using IntelliJ together with SBT. I've already found a way to convert .jar files into a Dll, using the ikvm-converter. Now the problem: When I use "package" under SBT to create a .jar file out of my .scala file and try to convert it afterwards with ikvmc into a Dll the resulting library is empty when integrated in C#...

For example converting the Jama-Library (which is written in Java) works fine, where converting Scama (written in Scala) does not work.

Is there a way to do this conversion of scala code into a dll? Is there a "Scala to Java"-conversion tool?

Best Regards, Christoph

I have no knowledge of .NET, but judging from SK-logic's and your comments to the questions: sbt package does not include the Scala runtime library, because it assumes you are going to export your project as a library to be used within other Scala projects.

Therefore, you will need to create a "fat" jar that contains the runtime. For example, in this blog you can see how the author creates a fully self-contained executable, by converting both the project jar and the runtime jar.

There are different tools to do that with sbt. The easiest would be sbt-assembly, but you will end up with a very large file, because it just adds the whole runtime. If that is a problem, you may want to filter the runtime instead, using the proguard plugin. More on this topic in another StackOverflow entry.
