Installing DMD on 64-bit Windows 7 (COFF-compatible)
Good day, fellow D developers. After spending much time figuring out how to make DMD work fluently under 64-bit Windows 7 I've realized that this is not a trivial task and lots of people might have trouble with this, so I've decided to post my solution, that might save people a lot of time.
As we know, there are compatibility problems with 32-bit DMD binaries, because they are compiled using DMC back-end, which can only produce OMF binaries, so in order to avoid problems with linking against externally compiled libraries, it's much easier to stick to 64-bit binaries, so that DMD will use the Visual Studio linker to produce compatible COFF binaries. Another problem is that 32-bit DMD binaries are linked against obsolete 32-bit WinAPI libraries, which lack some very important functions, while the 64-bit binaries are required to link with the 64-bit libraries, supplied by the the Windows SDK.
And here's how this could be arranged:
Prepare your development folder
- Create a folder with no spaces in its full path.
- Store its full path in the
Get the Windows SDK.
Download the Windows SDK
- Navigate to Microsoft Windows SDK for Windows 7 in a web browser.
- In the opened window click Download button.
- Make sure, that the Windows SDK installer (winsdk_web.exe) is downloaded.
Install the downloaded Windows SDK
- Navigate to the folder, where the Windows SDK installer was downloaded in a file browser.
- Double-click on the installer and agree to security warnings to launch it.
- Click next, read and agree to the license until you reach the 'Install Locations' screen.
- Store the path under Destination Folder for Tools in the
%DEV_DIR_WINSDK%(e.g. C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A) and click Next >.
- On the Installation Options uncheck everything except x64 Libraries and Visual C++ Compilers and click Next >.
- Confirm that everything is correct and click Next > to start installing.
- Make sure, that the installation is completed succesfully.
- Store the path to the installed Visual Studio C++ compiler into the
%DEV_DIR_MSVC%environment variable (e.g. C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC).
Get the DMD
- Navigate to dmd2beta in a web browser.
- Make sure, that the DMD compiler archive (dmd2beta.zip) is downloaded.
- Unzip the archive into
%DEV_DIR_ROOT%\Tools, so that the 'dmd2' folder in the archive will end up in '%DEV_DIR_ROOT%\Tools\dmd2'.
Adapt the compiler configuration to the development environment
- Open the file
%DEV_DIR_ROOT%\Tools\dmd2\windows\bin\sc.iniin a text editor.
- Replace the line
LIB=with the line
- Add -m64 to the 'DFLAGS' variable.
- Remove the lines
- Replace the line
LINKCMD64=with the line
LINKCMD64="%DEV_DIR_MSVC%\bin\amd64\link.exe"Now "%DEV_DIR_ROOT%\Tools\dmd2\windows\bin\dmd.exe" will always use the Windows SDK libraries and Visual C++ compiler to produce 64-bit COFF binaries.
I hope I was helpful, because when I started to set up a development environment under 64-bit Windows 7, I went through a lot of problems to get here and I'd love to have this HOWTO at that time.
