The root issue is that dlerror isn't reentrant or even thread safe. The solution implemented here is to make a yielding spin lock over an AtomicFlag. This is pretty hacky, but the best we can do at this point. As far as I can tell, it isn't possible to create a global mutex without having to initialize it in a single threaded context. The Windows code isn't affected since errno is thread-local on Windows and it's running in an atomically block to ensure there isn't a green thread context switch. Closes #8156 |

The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Quick Start
Windows
Note: Windows users should read the detailed getting started notes on the wiki. Even when using the binary installer the Windows build requires a MinGW installation, the precise details of which are not discussed here.
Linux / OS X
-
Install the prerequisites (if not already installed)
- g++ 4.4 or clang++ 3.x
- python 2.6 or later (but not 3.x)
- perl 5.0 or later
- gnu make 3.81 or later
- curl
-
Download and build Rust You can either download a tarball or build directly from the repo.
To build from the tarball do:
$ curl -O http://static.rust-lang.org/dist/rust-0.8.tar.gz $ tar -xzf rust-0.8.tar.gz $ cd rust-0.8
Or to build from the repo do:
$ git clone https://github.com/mozilla/rust.git $ cd rust
Now that you have Rust's source code, you can configure and build it:
$ ./configure $ make && make install
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;rustdoc
, the API-documentation tool, andrustpkg
, the Rust package manager and build system. -
Read the tutorial.

Enjoy!
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:
- Windows (7, Server 2008 R2), x86 only
- Linux (various distributions), x86 and x86-64
- OSX 10.6 ("Snow Leopard") or greater, x86 and x86-64
You may find that other platforms work, but these are our "tier 1" supported build environments that are most likely to work.
Rust currently needs about 1.8G of RAM to build without swapping; if it hits swap, it will take a very long time to build.
There is lots more documentation in the wiki.
