## Prerequisites

The D language track requires that you have the following software
installed on your system:

* a D version 2 compiler

### Prerequisite: D version 2 Compiler

On the D language's website [dlang.org](https://dlang.org) the most recent compiler
version of the reference compiler DMD (Digital Mars D) can be downloaded and installed:

#### Windows

* [Installer](http://downloads.dlang.org/releases/2.x/2.071.1/dmd-2.071.1.exe)
* or: [Archive](http://downloads.dlang.org/releases/2.x/2.071.1/dmd.2.071.1.windows.7z)
* using [chocolatey](https://chocolatey.org/packages/dmd): choco install dmd

#### Mac OS X

* .dmg [package](http://downloads.dlang.org/releases/2.x/2.071.0/dmd.2.071.0.dmg)
* or: [Archive](http://downloads.dlang.org/releases/2.x/2.071.0/dmd.2.071.0.osx.tar.xz)
* using [Homebrew](http://brew.sh/): brew install dmd

#### Linux / FreeBSD
To quickly install dmd within your user directory, run: *curl -fsS https://dlang.org/install.sh | bash -s dmd*

Packages for various distributions are provided:

* [ArchLinux](https://wiki.archlinux.org/index.php/D_(programming_language)
* [Debian/Ubuntu](http://d-apt.sourceforge.net/)
* [Fedora/CentOS](http://dlang.org/download.html#dmd)
* [Gentoo](https://wiki.gentoo.org/wiki/Dlang)
* [OpenSuse](http://dlang.org/download.html#dmd)

#### Other compilers
Besides the DMD reference compiler which uses its own backend, there are two other compilers that can
be fetched through the dlang.org download section:

* [GDC](http://gdcproject.org/downloads) which uses the GCC backend
* [LDC](https://github.com/ldc-developers/ldc#installation) based on the LLVM backend

GDC and LDC aren't always at the most recent DMD frontend's versions, but provide better optimization levels as well as
support for other platforms like e.g. ARM.

See the wiki for [more information](https://wiki.dlang.org/Compilers).

#### IDE support

There are also support for the D language in various IDEs e.g.
[VisualD](http://rainers.github.io/visuald/visuald/StartPage.html) for Visual Studio and
[D plugin](https://plugins.jetbrains.com/plugin/7727?pr=clion) for IntelliJ's CLion. See the wiki
for [more information](https://wiki.dlang.org/IDEs).
