## Building from Source
|
2013-07-18 23:27:43 +00:00
|
|
|
|
|
2014-01-11 14:19:38 +00:00
|
|
|
|
1. Make sure you have installed the dependencies:
|
2015-02-21 22:46:06 +00:00
|
|
|
|
|
2016-04-30 21:21:18 +00:00
|
|
|
|
* `g++` 4.7 or later or `clang++` 3.x
|
2016-02-13 20:19:44 +00:00
|
|
|
|
* `python` 2.7 (but not 3.x)
|
2015-02-21 22:46:06 +00:00
|
|
|
|
* GNU `make` 3.81 or later
|
2016-08-17 04:30:17 +00:00
|
|
|
|
* `cmake` 3.4.3 or later
|
2015-02-21 22:46:06 +00:00
|
|
|
|
* `curl`
|
|
|
|
|
* `git`
|
2015-02-13 17:26:44 +00:00
|
|
|
|
|
2015-02-18 21:46:20 +00:00
|
|
|
|
2. Clone the [source] with `git`:
|
2013-07-18 23:27:43 +00:00
|
|
|
|
|
2015-02-21 22:46:06 +00:00
|
|
|
|
```sh
|
|
|
|
|
$ git clone https://github.com/rust-lang/rust.git
|
|
|
|
|
$ cd rust
|
|
|
|
|
```
|
2013-07-18 23:27:43 +00:00
|
|
|
|
|
2015-02-16 04:20:25 +00:00
|
|
|
|
[source]: https://github.com/rust-lang/rust
|
|
|
|
|
|
|
|
|
|
3. Build and install:
|
2014-01-11 14:19:38 +00:00
|
|
|
|
|
2015-02-21 22:46:06 +00:00
|
|
|
|
```sh
|
|
|
|
|
$ ./configure
|
|
|
|
|
$ make && make install
|
|
|
|
|
```
|
2014-01-11 14:19:38 +00:00
|
|
|
|
|
2015-02-21 22:46:06 +00:00
|
|
|
|
> ***Note:*** 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.
|
2013-07-18 23:27:43 +00:00
|
|
|
|
|
|
|
|
|
When complete, `make install` will place several programs into
|
2014-02-02 07:56:55 +00:00
|
|
|
|
`/usr/local/bin`: `rustc`, the Rust compiler, and `rustdoc`, the
|
2015-02-16 04:41:16 +00:00
|
|
|
|
API-documentation tool. This install does not include [Cargo],
|
|
|
|
|
Rust's package manager, which you may also want to build.

### Building on Windows
|
|
|
|
|
|
2016-01-04 17:33:43 +00:00
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
#### MinGW
|
|
|
|
|
|
2016-06-27 23:02:06 +00:00
|
|
|
|
[MSYS2][msys2] can be used to easily build Rust on Windows:
|
2014-06-27 00:07:44 +00:00
|
|
|
|
|
2016-07-06 18:35:33 +00:00
|
|
|
|
[msys2]: https://msys2.github.io/
|
2014-06-27 00:07:44 +00:00
|
|
|
|
|
2016-06-27 23:02:06 +00:00
|
|
|
|
1. Grab the latest [MSYS2 installer][msys2] and go through the installer.
|
2015-02-21 22:46:06 +00:00
|
|
|
|
|
2016-06-27 23:02:06 +00:00
|
|
|
|
2. Run `mingw32_shell.bat` or `mingw64_shell.bat` from 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
|
|
|
|
|
-mingw32` or `msys2_shell.cmd -mingw64` from the command line instead)
|
2015-10-06 15:14:11 +00:00
|
|
|
|
|
2016-06-27 23:02:06 +00:00
|
|
|
|
3. From this terminal, install the required tools:
|
2015-03-14 23:09:26 +00:00
|
|
|
|
|
2016-06-09 19:05:46 +00:00
|
|
|
|
```sh
|
2016-06-27 23:02:06 +00:00
|
|
|
|
# Update package mirrors (may be needed if you have a fresh install of MSYS2)
|
|
|
|
|
$ pacman -Sy pacman-mirrors
|
2015-10-20 08:02:19 +00:00
|
|
|
|
|
2016-06-27 23:02:06 +00:00
|
|
|
|
# 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 the `python2` and `cmake` packages **not** used.
|
|
|
|
|
# The build has historically been known to fail with these packages.
|
|
|
|
|
$ pacman -S git \
|
|
|
|
|
make \
|
|
|
|
|
diffutils \
|
|
|
|
|
mingw-w64-x86_64-python2 \
|
|
|
|
|
mingw-w64-x86_64-cmake \
|
|
|
|
|
mingw-w64-x86_64-gcc
|
2015-02-21 22:46:06 +00:00
|
|
|
|
```
|
2014-06-27 00:07:44 +00:00
|
|
|
|
|
2016-06-27 23:02:06 +00:00
|
|
|
|
4. Navigate to Rust's source code (or clone it), then configure and build it:
|
2014-06-27 00:07:44 +00:00
|
|
|
|
|
2015-02-21 22:46:06 +00:00
|
|
|
|
```sh
|
|
|
|
|
$ ./configure
|
|
|
|
|
$ make && make install
|
|
|
|
|
```
|
2016-01-04 17:33:43 +00:00
|
|
|
|
|
|
|
|
|
#### MSVC
|
|
|
|
|
|
|
|
|
|
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”
|
2016-07-06 18:35:33 +00:00
|
|
|
|
option.
|
2016-01-04 17:33:43 +00:00
|
|
|
|
|
|
|
|
|
With these dependencies installed, the build takes two steps:
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
$ ./configure
|
|
|
|
|
$ make && make install
|
|
|
|
|
```
|
2014-06-27 00:07:44 +00:00
|
|
|
|
|
2016-06-27 17:51:27 +00:00
|
|
|
|
#### MSVC with rustbuild
|
|
|
|
|
|
2016-07-06 18:35:33 +00:00
|
|
|
|
The old build system, based on makefiles, is currently being rewritten into a
|
|
|
|
|
Rust-based build system called rustbuild. This can be used to bootstrap the
|
|
|
|
|
compiler on MSVC without needing to install MSYS or MinGW. All you need are
|
|
|
|
|
[Python 2](https://www.python.org/downloads/),
|
|
|
|
|
[CMake](https://cmake.org/download/), and
|
|
|
|
|
[Git](https://git-scm.com/downloads) in your PATH (make sure you do not use the
|
|
|
|
|
ones from MSYS if you have it installed). You'll also need Visual Studio 2013 or
|
|
|
|
|
newer with the C++ tools. Then all you need to do is to kick off rustbuild.
|
2016-06-27 17:51:27 +00:00
|
|
|
|
|
2016-07-06 18:35:33 +00:00
|
|
|
|
```
|
|
|
|
|
python .\src\bootstrap\bootstrap.py
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Currently rustbuild only works with some known versions of Visual Studio. If you
|
|
|
|
|
have a more recent version installed that a part of rustbuild 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.
|
|
|
|
|
|
|
|
|
|
```
|
2016-06-27 17:51:27 +00:00
|
|
|
|
CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat"
|
|
|
|
|
python .\src\bootstrap\bootstrap.py
|
|
|
|
|
```
|
|
|
|
|
|
2015-08-18 17:49:20 +00:00
|
|
|
|
## Building Documentation
|
|
|
|
|
|
|
|
|
|
If you’d like to build the documentation, it’s almost the same:
|
|
|
|
|
|
|
|
|
|
```sh
|
2016-06-30 13:15:17 +00:00
|
|
|
|
$ ./configure
|
2015-08-18 17:49:20 +00:00
|
|
|
|
$ make docs
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Building the documentation requires building the compiler, so the above
|
|
|
|
|
details will apply. Once you have the compiler built, you can
|
|
|
|
|
|
|
|
|
|
```sh
|
2015-10-20 08:02:19 +00:00
|
|
|
|
$ make docs NO_REBUILD=1
|
2015-08-18 17:49:20 +00:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
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 `doc` directory,
|
|
|
|
|
created by the `make` rule.
|
|
|
|
|
|
2013-07-18 23:27:43 +00:00
|
|
|
|
## 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.
|
2012-01-23 21:53:12 +00:00
|
|
|
|
|
2012-10-11 00:56:38 +00:00
|
|
|
|
Snapshot binaries are currently built and tested on several platforms:
|
2012-07-10 05:20:32 +00:00
|
|
|
|
|
2016-09-01 21:42:51 +00:00
|
|
|
|
| Platform / Architecture | x86 | x86_64 |

supported build environments that are most likely to work.

|
|
2016-06-27 17:51:27 +00:00
|
|
|
|
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.

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
|
2016-03-31 02:07:53 +00:00
|
|
|
|
Rust. And a good place to ask for help would be [#rust-beginners].
