Hey everyone,

While compiling our 64-bit app under Windows, DMD is getting out

I wasn't able to find a windows version of DMD64, is there even

for us.

Thanks in advance,

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

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.

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.

I second that. Either add a dmdx64.exe to the regular release or 
create a new package for it. It would be very nice to have. If we 
have to build it ourselves then it means that who ever builds x86 
can do it too and add it to the package quite easily.

I am having trouble building phobos for x64. Mainly runtime. This 
is due to the fact that the paths for druntime are hard coded to 
old visual studio versions. They should not be hard coded by 
attempt to detect(derive from registry settings or paths).

I get

--- errorlevel -1073741701

which is uninformative.

I was able to built for x86 without issue. (although phobos 
crapped out on trying to build druntime, I was able to build 
druntime first then phobos and it worked)

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.
