I found this code from this page:
http://rosettacode.org/wiki/Category:D

import std.stdio, std.socket;

void main(){
    writefln("%s", Socket.hostName());
}

When I tried to build it (I'm on Windows, anyway), I got this:
C:\Users\CSL-NB-064\Codes\D>dmd hostname.d

ws2_32.lib
 Warning 2: File Not Found ws2_32.lib
C:\dmd\lib\phobos.lib(socket)
 Error 42: Symbol Undefined _WSAIoctl@36
--- errorlevel 1

I did some Googling, and I found this http://www.digitalmars.com/d/archives/c++/2519.html. It looked interesting because MinGW, instead of DMC was used. So I downloaded Jan Knepper's implib, and extracted it into C:\dm\bin. This is my implib.ini: http://pastebin.com/iusxakcj

The next part is to build ws2_32.lib I copied ws2_32.dll from C:\Windows\System32 into C:\dmd\lib, and ran this command:
C:\dm\lib>implib /v /system /IC:\mingw\include /suffix ws2_32.dll ws2_32.dll

The output was:

Then I tried to compile once again, and the same error still happened.
Is there an easier way to get the importants libs?

I just remembered that the official dmd build has those libs. So I grab them and put them into C:\dmd\lib.

Still, the same error still happens. Maybe because I build dmd, druntime, and phobos from git?

Works for me :P

Have you downloaded and extracted a normal dmd 2.0 installation/zip?

If so, you should have:

  <some path>\dmd2\windows\lib\ws2_32.lib

and your

  <some path>\dmd2\windows\bin\sc.ini

should have something like:

  LIB="%@P%\..\lib";\dm\lib

which will point dmd at that ws2_32.lib file.

If you have those libs, and sc.ini, then perhaps all you're missing is the correct PATH setting, I have
  <some path>\dmd2\windows\bin

in my PATH.

If that doesn't help, or you already have it, I'd start by getting a normal installation/zip and see if it works, if so then replace the files you're (re-)building and try again - it should also work.

Actually I just solved the problem, by copying all the libs from dmd.2.0.59.zip into C:\dm\lib\

And this is my sc.ini:
[Environment]
LIB="C:\dmd\lib"
DFLAGS="-IC:\dmd\import" "-IC:\dmd\phobos"
LINKCMD=link.exe

That's odd.  I don't have ws2_32.lib in my dmc\dm\lib folder at all.

So, your sc.ini isn't pointing at dm\lib.. why would copying files there make it work?

My sc.ini has:

[Environment]
LIB="%@P%\..\lib";\dm\lib
DFLAGS="-I%@P%\..\..\src\phobos" "-I%@P%\..\..\src\druntime\import"
LINKCMD=%@P%\link.exe

%@P% resolves to the \dmd2\windows\bin folder so my LIB statement points first at dmd2\windows\lib which is where ws2_32.lib is.

I wonder.. Is dm\bin in your path?  If so link.exe in your case is probably dm\bin\link.exe and the sc.ini there has:

LIB="%@P%\..\lib";"%@P%\..\mfc\lib";%LIB%

which points to dm\lib.

If I were you, and you're not using dmc directly, I would remove dm\bin from the path and put dmd2\windows\bin there instead, then you should see the same behaviour as me.
