如何使用由D C库？ [英] How to use a C library from D?

问题描述

今天，我听到了D编程，它是为C code兼容。不过我还没有发现它是否可以使用C库像由D GTK或PortAudio的信息吗？
如果可能的话，你能解释一下如何做到这一点？

Today I heard about the D programming and that it is compatible to C code. Nevertheless I haven't found any information on whether it is possible to use C libraries like GTK or PortAudio from D? If it is possible, could you explain how to do this?

推荐答案

这是可以调用从D C库，你需要做的是C头文件转换为D.在大多数情况下，这是pretty简单，有一个很难使用的命令行工具帮助自动化过程。它从来没有真正为我工作的任何东西，但玩具的例子，但它可能是一个好的开始看到那种需要进行转换。只要把你遇到麻烦翻译片段成本身就是一个头，看看htod做它。

It is possible to call C libraries from D. What you need to do is to convert the C header files to D. For the most part this is pretty straightforward, and there is a hard-to-use command-line tool to help automate the process. It's never really worked for me on anything but toy examples, but it could be a good start to see the kind of transformations that need to be done. Just put a snippet you're having trouble translating into a header by itself and see what htod does with it.

您通常会遇到的最大问题是创造性的使用了C preprocessor的。有些东西可以变成版本（）语句D​​，但不是全部。

The biggest problem you'll usually encounter is creative use of the C preprocessor. Some things can be turned into version() statements in D, but not all.

至于实际编制，并与code连接，在类Unix平台我认为你可以编译和使用GCC的C code链接。在Windows上，你要么编译使用DMC和链路与DMD的C文件。或者你可以编译C code使用任意编译器，可这一点，然后用DMD链接，你需要做一个DMD兼容导入库出来的DLL的DLL。这可以使用在免费基本工具包中的IMPLIB工具从DigitalMars来完成。

As for actually compiling and linking with the code, on unix-like platforms I think you can compile and link in the C code using GCC. On Windows you either have to compile the C files using DMC and link with DMD. Or you can compile the C code into a DLL using any compiler capable of that, and then to link with DMD you need to make a DMD-compatible import lib out of the DLL. This can be done using the implib tool found in the free Basic Utilities Package available from DigitalMars.

还有很多这些头翻译已经完成。它先浏览绑定项目d源的，或要求在digitalmarsð新闻组首先着手的东西大如翻译GTK头前是非常有用的。很多流行的库，例如GTK已经被包裹（例如在这里： GTKD ）

There are also a lot of these header translations have already been done. It's useful to browse the Bindings project of Dsource first, or ask on the digitalmars D newsgroups first before embarking on something big like translating GTK headers. A lot of popular libraries like GTK have already been wrapped (e.g. here: GTKD)
