The Rust Programming Language
This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Building from Source
Make sure you have installed the dependencies:
g++4.7 or later or
python2.7 (but not 3.x)
make3.81 or later
cmake3.4.3 or later
Clone the source with
$ git clone https://github.com/rust-lang/rust.git $ cd rust
Build and install:
$ ./configure $ make && sudo make install
Note: Install locations can be adjusted by passing a
configure. Various other options are also supported – pass
--helpfor more information on them.
sudo 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
There are two prominent ABIs in use on Windows: the native (MSVC) ABI used by Visual Studio, and the GNU ABI used by the GCC toolchain. Which version of Rust you need depends largely on what C/C++ libraries you want to interoperate with: for interop with software produced by Visual Studio use the MSVC build of Rust; for interop with GNU software built using the MinGW/MSYS2 toolchain use the GNU build.
MSYS2 can be used to easily build Rust on Windows:
Grab the latest MSYS2 installer and go through the installer.
mingw64_shell.batfrom wherever you installed MSYS2 (i.e.
C:\msys64), depending on whether you want 32-bit or 64-bit Rust. (As of the latest version of MSYS2 you have to run
msys2_shell.cmd -mingw64from the command line instead)
From this terminal, install the required tools:
# Update package mirrors (may be needed if you have a fresh install of MSYS2) $ pacman -Sy pacman-mirrors # Install build tools needed for Rust. If you're building a 32-bit compiler, # then replace "x86_64" below with "i686". If you've already got git, python, # or CMake installed and in PATH you can remove them from this list. Note # that it is important that you do **not** use the 'python2' and 'cmake' # packages from the 'msys2' subsystem. The build has historically been known # to fail with these packages. $ pacman -S git \ make \ diffutils \ tar \ mingw-w64-x86_64-python2 \ mingw-w64-x86_64-cmake \ mingw-w64-x86_64-gcc
Navigate to Rust's source code (or clone it), then configure and build it:
$ ./configure $ make && make install
MSVC builds of Rust additionally require an installation of Visual Studio 2013
(or later) so
rustc can use its linker. Make sure to check the “C++ tools”
With these dependencies installed, you can build the compiler in a
> python x.py build
If you're running inside of an msys shell, however, you can run:
$ ./configure --build=x86_64-pc-windows-msvc $ make && make install
Currently building Rust only works with some known versions of Visual Studio. If you have a more recent version installed the build system doesn't understand then you may need to force rustbuild to use an older version. This can be done by manually calling the appropriate vcvars file before running the bootstrap.
CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat" python x.py build
If you’d like to build the documentation, it’s almost the same:
$ ./configure $ make docs
The generated documentation will appear in a top-level
created by the
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 between 600MiB and 1.5GiB to build, depending on platform. If it hits swap, it will take a very long time to build.
There is more advice about hacking on Rust in CONTRIBUTING.md.
The Rust community congregates in a few places:
- Stack Overflow - Direct questions about using the language.
- users.rust-lang.org - General discussion and broader questions.
- /r/rust - News and general discussion.

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 would be #rust-beginners.
