# The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and
documentation.
## Quick Start
### Windows
1. Download and use the [installer][win-exe].
2. Read the [tutorial].
2. Enjoy!
> ***Note:*** Windows users should read the detailed
> [getting started][wiki-start] notes on the wiki. Even when using
> the binary installer the Windows build requires a MinGW installation,
> the precise details of which are not discussed here.

[win-exe]: http://static.rust-lang.org/dist/rust-0.8-install.exe
### Linux / OS X
1. Install the prerequisites (if not already installed)
* g++ 4.4 or clang++ 3.x
* python 2.6 or later (but not 3.x)
* perl 5.0 or later
* gnu make 3.81 or later
* curl
2. Download and build Rust
You can either download a [tarball] or build directly from the [repo].
To build from the [tarball] do:
2013-09-22 01:25:08 +02:00
$ curl -O http://static.rust-lang.org/dist/rust-0.8.tar.gz
$ tar -xzf rust-0.8.tar.gz
$ cd rust-0.8
Or to build from the [repo] do:
$ git clone https://github.com/mozilla/rust.git
$ cd rust
Now that you have Rust's source code, you can configure and build it:
$ ./configure
$ make && make install
You may need to use `sudo make install` if you do not normally have
permission to modify the destination directory. The install locations can
be adjusted by passing a `--prefix` argument to `configure`. Various other
options are also supported, pass `--help` for more information on them.
When complete, `make install` will place several programs into
`/usr/local/bin`: `rustc`, the Rust compiler; `rustdoc`, the
API-documentation tool, and `rustpkg`, the Rust package manager and build
system.
3. Read the [tutorial].

## Notes
Since the Rust compiler is written in Rust, it must be built by a
precompiled "snapshot" version of itself (made in an earlier state of
development). As such, source builds require a connection to the Internet, to
fetch snapshots, and an OS that can execute the available snapshot binaries.
Snapshot binaries are currently built and tested on several platforms:
2012-07-10 07:20:32 +02:00
* Windows (7, Server 2008 R2), x86 only
* Linux (various distributions), x86 and x86-64
* OSX 10.6 ("Snow Leopard") or greater, x86 and x86-64
You may find that other platforms work, but these are our "tier 1"
supported build environments that are most likely to work.
Rust currently needs about 1.8G of RAM to build without swapping; if it hits
swap, it will take a very long time to build.
There is lots more documentation in the [wiki].
