According to apple's documentation of rpath semantics, `@executable_path` means that the path is relative the the *process executable*, not necessarily the library in question. On the other hand, `@loader_path` is the path that points to the library which contains the `@loader_path` reference. All of our rpath usage is based off the library or executable, not just the executable. This means that on OSX we should be using `@loader_path` instead of `@executable_path` to achieve the same semantics as linux's $ORIGIN. The purpose of this is to unblock the current snapshot from landing. It appears that because we were propagating linker arguments we never saw this before. Now that we're no longer printing linker arguments, we're depending on the libraries to resolve their own references. In using `@executable_path` on OSX, libraries in different locations than the executable were not able to resolve their references (because their rpaths listed were all relative to the location of the library, not the executable). I'm still a little unclear on how this ever passed locally on my own machine, but it's clear why this is failing on the bots at least.
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-0.8Or to build from the repo do:
$ git clone https://github.com/mozilla/rust.git $ cd rustNow that you have Rust's source code, you can configure and build it:
$ ./configure $ make && make installYou may need to use
sudo make installif you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a--prefixargument toconfigure. Various other options are also supported, pass--helpfor more information on them.When complete,
make installwill place several programs into/usr/local/bin:rustc, the Rust compiler;rustdoc, the API-documentation tool, andrustpkg, the Rust package manager and build system. -

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.
