Re: Had not Dllimport in D?
Okay, since you clearly have not worked in a native language before, lets start from scratch. You want to make some bindings to a shared library called "msvcrt-ruby18". From this I know that it is using the Microsoft Visual C runtime. That means you must build D using this as well. This is done via the -ms32coff switch for 32bit and -m64 for 64bit (which is easier all up). You will need Visual studio with all of the c/c++ stuff installed. Keep in mind you must match the version of Visual C runtime up with the shared libraries one (if you fail enjoy the segfaults!). Lastly you want some bindings. I won't cover that here. But this should help ya out http://dlang.org/spec/interfaceToC.html After this you should be able to pass the shared library directly to dmd when in -ms32coff or -m64 mode and it'll all work.

Had not Dllimport in D?
First, I really sorry my bad english.
I just want to using Ruby dll file(msvcrt-ruby220.dll).
In the case of C#,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using INT = System.Int32;
namespace RubyTest01
{
static class Ruby
{
public const string RubyDll = "msvcrt-ruby18";
[DllImport(RubyDll)]
public static extern void ruby_init();
[DllImport(RubyDll)]
public static extern INT rb_eval_string_protect(byte[]
script, ref INT state);
public static INT rb_eval_string_protect(string script, ref
INT state)
{
return
rb_eval_string_protect(Encoding.UTF8.GetBytes(script + '\0'), ref
state);
}
}
class Program
{
static void Main(string[] args)
{
INT state = 0;
Ruby.ruby_init();
Ruby.rb_eval_string_protect("open('test.txt', 'w') {| fp|
fp.write(\"Hello World!\\n\")}", ref state);
}
}
I guess D had something like it, but i don't know how to do it.
Thx!
