If you're looking for a stable version of D, you probably want to download the official releases. This page is for those who want to try out D on platforms that aren't yet officially supported, those who are adventurous and wish to try out the latest development (unstable!) version of D, and developers who wish to contribute to D development.
Contents
Getting the sources
Official releases
The official release of DMD is available from the official download page.
Latest git
This is for those who want to test or contribute to the development version of D. The latest source code for the D compiler, runtime library, and standard library are available on GitHub. To build a working D compiler toolchain, you will need to checkout at least dmd, druntime, and phobos.
Source code structure
The D source code assumes a particular directory structure, which you probably would want to adopt so that you don't have to fiddle with the Makefiles all the time.
Posix
For Posix, it is assumed that you will have a common root directory where the compiler and library sources will sit under. For example, you can choose the common root directory to be /usr/src/d, then you can checkout the sources under this directory:
mkdir /usr/src/d
cd /usr/src/d
git clone git://github.com/D-Programming-Language/dmd.git
git clone git://github.com/D-Programming-Language/druntime.git
git clone git://github.com/D-Programming-Language/phobos.git
Optionally, if you want some related tools, you can also checkout tools.git:
git clone git://github.com/D-Programming-Language/tools.git
Note: if you're planning to submit pull requests, you should replace the above URLs with the URLs for your fork of the official sources, not the official sources themselves.
You should end up with this directory structure:
/usr/src/d/ /usr/src/d/dmd /usr/src/d/druntime /usr/src/d/phobos (/usr/src/d/tools)
Windows
For windows, you can follow the first posix steps regarding checking out files from github.
You can checkout the sources wherever you like. If we call %DM_HOME% the root path, the it is recommended to have this structure:
%DM_HOME%\dmd2\src %DM_HOME%\dmd2\src\dmd %DM_HOME%\dmd2\src\druntime %DM_HOME%\dmd2\src\phobos
Additionally, you should extract the digital mars compiler inside %DM_HOME%, alongside dmd2. You should finally create a {{code|windows directory with a bin and lib directory inside it. Your final structure should look like this:
%DM_HOME%\dm %DM_HOME%\dmd2\src %DM_HOME%\dmd2\src\dmd %DM_HOME%\dmd2\src\druntime %DM_HOME%\dmd2\src\phobos %DM_HOME%\dmd2\windows %DM_HOME%\dmd2\windows\bin %DM_HOME%\dmd2\windows\lib
Building the sources
Posix
See also Alex Rønne Petersen's blog post on building DMD
Assuming your sources are checked out in /usr/src/d, you can do the following to build them:
cd /usr/src/d/dmd/src
make -f posix.mak
cd ../../druntime
make -f posix.mak DMD=../dmd/src/dmd
cd ../phobos
make -f posix.mak DMD=../dmd/src/dmd
Note that the compiler, runtime library, and standard library have to be built in that order, as each depends on the previous one. The addition of the build option DMD=../dmd/src/dmd ensures that your newly-built dmd is being used to build druntime and phobos.
If you're using a 64-bit platform, you may want to append MODEL=64 to your make commands, as the default makefiles will build for 32-bit:
cd /usr/src/d/dmd/src
make -f posix.mak MODEL=64
cd ../../druntime
make -f posix.mak MODEL=64 DMD=../dmd/src/dmd
cd ../phobos
make -f posix.mak MODEL=64 DMD=../dmd/src/dmd
Parallel make can drastically speed up compilation times. The -j<integer> option allows you to specify the number of job slots. Number_of_cores + 1 is a often a good choice E.g.:
make -f posix.mak -j5
for a machine with 4 cores.
After building, you should have a working D compiler in /usr/src/d/dmd/src/dmd. You may need to edit dmd.conf so that the compiler can find druntime and phobos. You dmd.conf should contain:
[Environment] DFLAGS=-I/path/to/src/phobos -I/path/to/src/druntime/import -L-L/path/to/libs -L--no-warn-search-mismatch -L--export-dynamic
Where the first two flags (-I) must be followed by the path to src/phobos et src/druntime/import. The -L-L flag must be followed by the path to libphobos.a (for example: -L-L/usr/local/lib/lib64).
You should probably also run the unittests to make sure your build is working correctly:
cd ../druntime
make -f posix.mak -j5 unittest
cd ../phobos
make -f posix.mak -j5 unittest
(Running the unittests with -j is recommended if you have a multicore CPU, as some of them may take a while to run.)
Installation
posix.mak does not come with an install option (user supplied sample install script here: Attachment:posix-make-install-dmd.sh), but you can copy files manually to an appropriate location such as /usr/local or /opt/dmd. For example:
cd /usr/src/d/dmd/src
mkdir /opt/dmd
mkdir /opt/dmd/bin
cp dmd /opt/dmd/bin
cd ../../druntime
mkdir /opt/dmd/include
mkdir /opt/dmd/include/d2
cp -r import/* /opt/dmd/include/d2
cd ../phobos
mkdir /opt/dmd/lib
cp generated/linux/release/64/libphobos2.a /opt/dmd/lib # for 64-bit version
cp generated/linux/release/32/libphobos2.a /opt/dmd/lib # for 32-bit version
cp -r std /opt/dmd/include/d2
cp -r etc /opt/dmd/include/d2
Then, create the following dmd.conf in the /opt/dmd/bin directory:
[Environment]
DFLAGS=-I/opt/dmd/include/d2 -L-L/opt/dmd/lib -L--no-warn-search-mismatch -L--export-dynamic
Note that you will have to add /opt/dmd/bin to your PATH to make use of your newly installed DMD.
Uninstallation is then as simple as removing the /opt/dmd directory.
Windows
The following instructions work for win32. May or may not work with win64. This scheme is a suggestion.
Assuming your sources are checked out C:\D, and that make from digital mars is in your path, you can do the following to build them:
set DM_HOME=C:\D
cd %DM_HOME%\dmd2\src\dmd\src
make -fwin32.mak -release
From there, it is suggested to move the built binaries into your %DM_HOME%\windows\bin directory, and add that to your path:
copy *.exe %DM_HOME%\dmd2\windows\bin
set path=%path%;%DM_HOME%\dmd2\windows\bin
From there, you have to create a sc.ini in your DMD.exe directory. It is suggested to just copy paste the one provided in the packaged D2·110·0, instead of writing your own.
Now build druntime:
cd %DM_HOME%\dmd2\src\druntime
make -fwin32.mak
And phobos:
cd %DM_HOME%\dmd2\src\phobos
make -fwin32.mak
You should copy the phobos lib into your windows\lib folder:
copy phobos.lib %DM_HOME%\dmd2\windows\lib
Optionally, you can build rdmd from source if you have checked out tools in your sources:
cd %DM_HOME%\dmd2\src\tools
make -fwin32.mak rdmd.exe
copy *.exe %DM_HOME%\dmd2\windows\bin
The last step is getting the additional libs. curl for D2 can be found at the bottom of the download section of dlang.org: [download].
Additional libs that are necessary can simply be copy pasted from the D2·110·0 package (without overwriting your phobos.lib)
The very last step is to verify that everything works by unittesting phobos:
cd %DM_HOME%\dmd2\src\phobos
make -fwin32.mak unittest
Common Windows issues
If when building druntime you get errors about missing MASM386, it's due to a required assembling of a file called minit.asm. However the druntime repository includes a prebuilt minit.obj file so you shouldn't need to assemble it again. As a workaround for the make error create an empty masm386.bat file and put it in a directory that's in your PATH.
Additional Tools
If you cloned D-Programming-Language/tools.git, you also have a tools folder where small helping programs live. There is no need to build them, you can just compile them using DMD:
dmd rdmd.d;
dmd ddemangle.d;
dmd dtab;
dmd tolf;
rdmd builds your D modules automatically, from the one containing main. It'll deduce dependencies and compile/link them for you. ddemangle will demangle its input, replacing all mangled D symbols with their unmangled form. dtab transforms tabs into spaces in source code. tolf replaces line endings with LF.
Using dtab and tolf is a good idea if you want to contribute to the D-Programming-Language repos.
