I'm trying to compile my project as a Win64 application but this is happening:

Building C:\Users\me\test\test.exe...
OPTLINK (R) for Win32  Release 8.00.17
Copyright (C) Digital Mars 1989-2013  All rights reserved.

^
Building C:\Users\me\test\test.exe failed!


I'm on a Win64 machine and compiling Win32 works fine. I'm using Visual Studio 17 Community with Visual D. DMD is up to date as is Visual D.

I added a x64 "solution platform" to the configuration manager which added a -m64 flag to my linker options. I'm not sure what else I'm meant to do to get it to compile as x64?

I'm not sure why its trying to use opt link for 64-bit, the linker banner gives a hint:
OPTLINK (R) for _Win32_.

64 bit should use MS's linker, is -m64 only passed to the linker but not the compiler?

this should be ok, can you post error when using with m64

That usually happens if the DMD bin folder is searched first in the PATH variable (unfortunately the linker and other tools have the same name as the Microsoft programs).

You should verify that the VC folder is listed first in Tools->Options->Projects and Solutions->Visual D Settings->DMD Directories->x64->Executable Paths, i.e.

$(VCTOOLSINSTALLDIR)bin\HostX86\x86

should be listed before

$(DMDInstallDir)windows\bin
