Compiler for D Programming Language

This is the D compiler for Win32.

Global compiler settings
\dmd\lib\phobos.lib

Sample D programs

Requirements

Installation

Unzip the files in the root directory. It will create a \dmd directory with all the files in it. All the tools are command line tools, which means they are run from a console window. Create a console window in Windows XP by clicking on [Start][Command Prompt].

Example

Run:
	\dmd\bin\shell all.sh
	
in the \dmd\samples\d directory for several small examples.

Compiler Arguments and Switches

dmd files... -switch...

files...
Extension File Type
none D source files
.d D source files
.obj Object files to link in
.exe Name output executable file
.def module definition file
.res resource file
-c
compile only, do not link
-d
allow deprecated features
-debug
compile in debug code
-debug=level
compile in debug code <= level
-debug=ident
compile in debug code identified by ident
-g
add symbolic debug info
-gt
add trace profiling hooks
-inline
inline expand functions
-Ipath
where to look for imports. path is a ; separated list of paths. Multiple -I's can be used, and the paths are searched in the same order.
-Llinkerflag
pass linkerflag to the linker, for example, /ma/li
-O
optimize
-oobjdir
write object files to directory objdir instead of to the current directory
-release
compile release version
-unittest
compile in unittest code
-v
verbose
-version=level
compile in version code >= level
-version=ident
compile in version code identified by ident

Linking

Linking is done directly by the dmd compiler after a successful compile. To prevent dmd from running the linker, use the -c switch.

The programs must be linked with the D runtime library phobos.lib, followed by the C runtime library snn.lib. This is done automatically as long as the directories for the libraries are on the LIB environment variable path. A typical way to set LIB would be:

	set LIB=\dmd\lib;\dm\lib
	

Environment Variables

The D compiler dmd uses the following environment variables:
DFLAGS
The value of DFLAGS is treated as if it were appended to the command line to dmd.exe.
LIB
The linker uses LIB to search for library files. For D, it will normally be set to:
	set LIB=\dmd\lib;\dm\lib
LINKCMD
dmd normally runs the linker by looking for link.exe along the PATH. To use a specific linker instead, set the LINKCMD environment variable to it. For example:
	set LINKCMD=\dm\bin\link
PATH
If the linker is not found in the same directory as dmd.exe is in, the PATH is searched for it. Note: other linkers named link.exe will likely not work. Make sure the Digital Mars link.exe is found first in the PATH before other link.exe's, or use LINKCMD to specifically identify which linker to use.

SC.INI Initialization File

dmd will look for the initialization file sc.ini in the same directory dmd.exe resides in. If found, environment variable settings in the file will override any existing settings. This is handy to make dmd independent of programs with conflicting use of environment variables.

Environment variables follow the [Environment] section heading, in name=value pairs. Comments are lines that start with ;. For example:

	; sc.ini file for dmd
	; Names enclosed by %% are searched for in the existing environemnt
	; and inserted. The special name %@P% is replaced with the path
	; to this file.
	[Environment]
	LIB="%@P%\..\lib";\dm\lib
	DFLAGS="-I%@P%\..\src\phobos"
	LINKCMD="%@P%\..\..\dm\bin"
