mk: Build crates with relative source file paths The path we pass to rustc will be visible in panic messages and backtraces: they will be user visible! Avoid junk in these paths by passing relative paths to rustc. For most advanced users, `libcore` or `libstd` in the path will be a clue to the location -- inside our code, not theirs. Store both the relative path to the source as well as the absolute. Use the relative path where it matters, compiling the main crates, instead of changing all of the build process to cope with relative paths. Example output after this patch: ``` $ ./testunwrap thread '<main>' panicked at 'called `Option::unwrap()` on a `None` value', ../src/libcore/option.rs:362 $ RUST_BACKTRACE=1 ./testunwrap thread '<main>' panicked at 'called `Option::unwrap()` on a `None` value', ../src/libcore/option.rs:362 stack backtrace: 1: 0x7ff59c1e9956 - sys::backtrace::write::h67a542fd2b201576des at ../src/libstd/sys/unix/backtrace.rs:158 2: 0x7ff59c1ed5b6 - panicking::on_panic::h3d21c41cdd5c12d41Xw at ../src/libstd/panicking.rs:58 3: 0x7ff59c1e7b6e - rt::unwind::begin_unwind_inner::h9f3a5440cebb8baeLDw at ../src/libstd/rt/unwind/mod.rs:273 4: 0x7ff59c1e7f84 - rt::unwind::begin_unwind_fmt::h4fe8a903e0c296b0RCw at ../src/libstd/rt/unwind/mod.rs:212 5: 0x7ff59c1eced7 - rust_begin_unwind 6: 0x7ff59c22c11a - panicking::panic_fmt::h00b0cd49c98a9220i5B at ../src/libcore/panicking.rs:64 7: 0x7ff59c22b9e0 - panicking::panic::hf549420c0ee03339P3B at ../src/libcore/panicking.rs:45 8: 0x7ff59c1e621d - option::Option<T>::unwrap::h501963526474862829 9: 0x7ff59c1e61b1 - main::hb5c91ce92347d1e6eaa 10: 0x7ff59c1f1c18 - rust_try_inner 11: 0x7ff59c1f1c05 - rust_try 12: 0x7ff59c1ef374 - rt::lang_start::h7e51e19c6677cffe5Sw at ../src/libstd/rt/unwind/mod.rs:147 at ../src/libstd/rt/unwind/mod.rs:130 at ../src/libstd/rt/mod.rs:128 13: 0x7ff59c1e628e - main 14: 0x7ff59b3f6b44 - __libc_start_main 15: 0x7ff59c1e6078 - <unknown> 16: 0x0 - <unknown> ``` |

The Rust Programming Language
Rust is a systems programming language that is fast, memory safe and multithreaded, but does not employ a garbage collector or otherwise impose significant runtime overhead.
This repo contains the code for rustc
, the Rust compiler, as well
as standard libraries, tools and documentation for Rust.
Quick Start
Read "Installing Rust" from The Book.
Building from Source
-
Make sure you have installed the dependencies:
g++
4.7 orclang++
3.xpython
2.6 or later (but not 3.x)- GNU
make
3.81 or later curl
git
-
Clone the source with
git
:$ 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 install
if you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a--prefix
argument toconfigure
. 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, andrustdoc
, 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
mingw64
toolchain and other required tools.# Choose one based on platform: $ pacman -S mingw-w64-i686-toolchain $ pacman -S mingw-w64-x86_64-toolchain $ pacman -S base-devel
-
Run
mingw32_shell.bat
ormingw64_shell.bat
from wherever you installed MYSY2 (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
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:
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.
There is more advice about hacking on Rust in CONTRIBUTING.md.
Getting Help
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.
Contributing
To contribute to Rust, please see CONTRIBUTING.
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.
