Hi,

Is there a 64-bit version of DMD for windows?

The download page offers only an x86 version. Or am I reading too much into that?

Cheers, buk

Hi!

DMD currently does not target 64-bit Windows.

You may have some luck with GDC (there is a 64-bit build from July in Downloads):

There's not much you would need a 64-bit compiler for on Windows.  What are you going to use it for?

Um, to build 64-bit programs? What else...

now what is this for a strange comment? you need 64bit for windows for the same reasons than for any other platform: accessing loads of mem. yes, for some this is really important! for me it is actually a dealbreaker - i'd love to use D for my scientific programming, but my datasets often reach several GB...

my computer has 16GB and i intend to make use of them.

Use Linux.. it's better for your health ;p

jk, I'm eagerly awaiting a Win64 DMD as well.

Scientific programming on Windoze? You can't be serious :P

lol, that's not even the only issue.

32-bit programs can't show 64-bit dialogs. So "Open this file..." actually shows the SysWOW64 folder instead of the System32 folder, and there's _no way_ to bypass this unless you build a 64-bit app.

Most people are not actually doing scientific programming.  And they
don't actually need to open an open file dialog to access files that are
in the "real" System32.  But if they do, there are several easy
solutions.[1]  Another reason for needing a 64-bit program on Windows
would be if you are creating a shell extension.  TortoiseSVN comes in
both 32-bit and 64-bit flavors for this reason.

People coming from Linux are accustomed to a running only 64-bit
programs if they have a 64-bit OS.  That's simply because Linux is
usually distributed through downloading.  To limit the download size,
they leave out the 32-bit versions of libraries.  Which means you can't
actually run 32-bit programs without downloading and installing the
packages containing those libraries first.  At least that's my
understanding.

This issue doesn't exist on Windows.  Probably not on OS X either, but
I'm not too familiar with that system.

So when people ask for 64-bit versions without stating why they need it,
I always have to ask what features they want that the 32-bit version
doesn't have.

Mac OS X has universal binaries, that is, libraries and executables containing code for multiple architectures. All system libraries bundled with the OS are compiled (at least) both for 32 and 64bit. This makes it no problem running either 32 or 64bit applications, the user don't have to know or care.
