The Rust Programming Language
Rust is a fast systems programming language that guarantees memory safety and offers painless concurrency (no data races). It does not employ a garbage collector and has minimal runtime overhead.
This repo contains the code for the compiler (
rustc), as well
as standard libraries, tools and documentation for Rust.
Building from Source
Make sure you have installed the dependencies:
python2.6 or later (but not 3.x)
make3.81 or later
Clone the source with
$ git clone https://github.com/rust-lang/rust.git $ cd rust
Build and install:
$ ./configure $ make && make install
Note: You may need to use
sudo make installif you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a
configure. Various other options are also supported – pass
--helpfor more information on them.
make installwill place several programs into
rustc, the Rust compiler, and
rustdoc, the API-documentation tool. This install does not include Cargo, Rust's package manager, which you may also want to build.
Building on Windows
MSYS2 can be used to easily build Rust on Windows:
Grab the latest MSYS2 installer and go through the installer.
From the MSYS2 terminal, install the
mingw64toolchain and other required tools.
# Update package mirrors (may be needed if you have a fresh install of MSYS2) $ pacman -Sy pacman-mirrors # Choose one based on platform: # *** see the note below *** $ pacman -S mingw-w64-i686-toolchain $ pacman -S mingw-w64-x86_64-toolchain # Make git available in MSYS2 (if not already available on path) $ pacman -S git $ pacman -S base-devel
mingw64_shell.batfrom wherever you installed MSYS2 (i.e.
C:\msys), depending on whether you want 32-bit or 64-bit Rust.
Navigate to Rust's source code, configure and build it:
$ ./configure $ make && make install
Note: gcc versions >= 5 currently have issues building LLVM on Windows resulting in a segmentation fault when building Rust. In order to avoid this it may be necessary to obtain an earlier version of gcc such as 4.9.x.
pacmanwill install the latest version, so for the time being it is recommended to skip gcc toolchain installation step above and use Mingw-Builds project's installer instead. Be sure to add gcc
bindirectory to the path before running
For more information on this see issue #28260.
If you’d like to build the documentation, it’s almost the same:
./configure $ make docs
Building the documentation requires building the compiler, so the above details will apply. Once you have the compiler built, you can
$ make docs NO_REBUILD=1
To make sure you don’t re-build the compiler because you made a change to some documentation.
The generated documentation will appear in a top-level

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:
|Platform \ Architecture||x86||x86_64|
|Windows (7, 8, Server 2008 R2)||✓||✓|
|Linux (2.6.18 or later)||✓||✓|
|OSX (10.7 Lion or later)||✓||✓|
You may find that other platforms work, but these are our officially supported build environments that are most likely to work.
Rust currently needs about 1.5 GiB of RAM to build without swapping; if it hits swap, it will take a very long time to build.

Rust has an IRC culture and most real-time collaboration happens in a variety of channels on Mozilla's IRC network, irc.mozilla.org. The most popular channel is #rust, a venue for general discussion about Rust, and a good place to ask for help.
