Hey everyone,

While compiling our 64-bit app under Windows, DMD is getting out of memory.
I wasn't able to find a windows version of DMD64, is there even one? If not, are there any plans? This is quite a show stopper for us.

Thanks in advance,
Mario

What do you mean by 64bit app? How much memory do you have? How big is your codebase?

yes support for 64bit is there for a few years.
just download latest dmd https://dlang.org/download.html#dmd
and use -m64 flag when compiling

Yep, that make sense :)

Yes, that's the case.

Have you tried ldc2 (ldmd2)?

I haven't tried it yet, but I would want to avoid changing the compiler at this point, since we already have all our tooling build around DMD.

That is why I'm asking specifically about the state of the 64-bit windows version of DMD.

There is no official 64 bit build of DMD, but it's quite easy to make one yourself using Digger:

https://github.com/CyberShadow/Digger

Since the 64 bit build is not automatically tested master will sometimes fail to compile, but sticking to releases always works for me so far.

If you have VisualD installed just check out the dlang/dmd repository on github using the last release branch and open the visual studio solution inside the "vcbuild" directory. Then build the x64 version of ddmd and use that. It is safe to rename the resulting binary from "ddmd.exe" to "dmd.exe". You can replace dmd.exe in your install with this newly build executable and everything will work.

Thanks all for the info, I build it locally as suggested.

Still not sure why there is not an official release it since it is already being supported. I would suggest doing it so if possible.
