15 ## Building from Source
17 1. Make sure you have installed the dependencies:
19 * `g++` 4.7 or `clang++` 3.x
20 * `python` 2.7 (but not 3.x)
21 * GNU `make` 3.81 or later
25 2. Clone the [source] with `git`:
28 $ git clone https://github.com/rust-lang/rust.git
32 [source]: https://github.com/rust-lang/rust
38 $ make && make install
41 > ***Note:*** You may need to use `sudo make install` if you do not
42 > normally have permission to modify the destination directory. The
43 > install locations can be adjusted by passing a `--prefix` argument
44 > to `configure`. Various other options are also supported – pass
45 > `--help` for more information on them.
47 When complete, `make install` will place several programs into
48 `/usr/local/bin`: `rustc`, the Rust compiler, and `rustdoc`, the
49 API-documentation tool. This install does not include [Cargo],
50 Rust's package manager, which you may also want to build.

54 ### Building on Windows
56 There are two prominent ABIs in use on Windows: the native (MSVC) ABI used by
57 Visual Studio, and the GNU ABI used by the GCC toolchain. Which version of Rust
58 you need depends largely on what C/C++ libraries you want to interoperate with:
59 for interop with software produced by Visual Studio use the MSVC build of Rust;
60 for interop with GNU software built using the MinGW/MSYS2 toolchain use the GNU
66 [MSYS2](http://msys2.github.io/) can be used to easily build Rust on Windows:
68 1. Grab the latest MSYS2 installer and go through the installer.
70 2. From the MSYS2 terminal, install the `mingw64` toolchain and other required
74 # Update package mirrors (may be needed if you have a fresh install of MSYS2)
75 $ pacman -Sy pacman-mirrors
79 here](http://mingw-w64.org/doku.php/download/mingw-builds), and choose the
80 `version=4.9.x,threads=win32,exceptions=dwarf/seh` flavor when installing. Also, make sure to install to a path without spaces in it. After installing,
81 add its `bin` directory to your `PATH`. This is due to [#28260](https://github.com/rust-lang/rust/issues/28260), in the future,
82 installing from pacman should be just fine.
85 # Make git available in MSYS2 (if not already available on path)
88 $ pacman -S base-devel
91 3. Run `mingw32_shell.bat` or `mingw64_shell.bat` from wherever you installed
92 MSYS2 (i.e. `C:\msys`), depending on whether you want 32-bit or 64-bit Rust.
94 4. Navigate to Rust's source code, configure and build it:
98 $ make && make install
103 MSVC builds of Rust additionally require an installation of Visual Studio 2013
104 (or later) so `rustc` can use its linker. Make sure to check the “C++ tools”
105 option. In addition, `cmake` needs to be installed to build LLVM.
107 With these dependencies installed, the build takes two steps:
111 $ make && make install
114 ## Building Documentation
116 If you’d like to build the documentation, it’s almost the same:
123 Building the documentation requires building the compiler, so the above
124 details will apply. Once you have the compiler built, you can
127 $ make docs NO_REBUILD=1
130 To make sure you don’t re-build the compiler because you made a change
131 to some documentation.
133 The generated documentation will appear in a top-level `doc` directory,
134 created by the `make` rule.
138 Since the Rust compiler is written in Rust, it must be built by a
139 precompiled "snapshot" version of itself (made in an earlier state of
140 development). As such, source builds require a connection to the Internet, to
141 fetch snapshots, and an OS that can execute the available snapshot binaries.
143 Snapshot binaries are currently built and tested on several platforms:
145 | Platform \ Architecture | x86 | x86_64 |
146 |--------------------------------|-----|--------|
147 | Windows (7, 8, Server 2008 R2) | ✓ | ✓ |
148 | Linux (2.6.18 or later) | ✓ | ✓ |
149 | OSX (10.7 Lion or later) | ✓ | ✓ |
151 You may find that other platforms work, but these are our officially
152 supported build environments that are most likely to work.
154 Rust currently needs between 600MiB and 1.5GiB to build, depending on platform. If it hits
155 swap, it will take a very long time to build.
