The Rust Programming Language

This is a compiler for Rust, including standard libraries, tools and documentation.

Installation

The Rust compiler currently must be built from a tarball, unless you are on Windows, in which case using the installer is recommended.

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.

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.

To build from source you will also need the following prerequisite packages:

  • 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

Assuming you're on a relatively modern *nix system and have met the prerequisites, something along these lines should work.

$ wget http://static.rust-lang.org/dist/rust-0.5.tar.gz
$ tar -xzf rust-0.5.tar.gz
$ cd rust-0.5
$ ./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 to configure. 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, and cargo, the Rust package manager.

The tutorial is a good starting point.

========================== Steps for Android Target addtion =======================

  1. setup android ndk standalone tool chain with platform=14 option

    Android NDK can be downloaded from http://developer.android.com/tools/sdk/ndk/index.html

    example command to setup standalone tool chain:

    ~/work/toolchains/android-ndk-r8c/build/tools$ ./make-standalone-toolchain.sh --platform=android-14 --install-dir=/home/ubuntu/work/toolchains/ndk_standalone --ndk-dir=/home/ubuntu/work/toolchains/android-ndk-r8c

  2. Download rustc from git repository

    a. git clone http://github.com/webconv/rust.git

    b. cd rust

    c. mkdir build

    d. cd build

  3. Create Makefile using CMake

    cmake ../ -DTargetOsType=android -DTargetCpuType=arm -DToolchain=path_of_standalone_toolchain_dir

  4. Build libuv and llvm

    make libuv

    make llvm

  5. Create Makefile again (the Makefile made in step 3 does not contain information of llvm)

    cmake ../

  6. Build Rustc ( make and make install have been separated)

    a.make

    b.make install [ it will copy ARM libraries into /usr/local/lib/rustc/arm-unknown-android/lib

  7. How to cross compiler

    rustc --target arm-unknown-android hello.rs

  8. How to run on Android

    use adb -e push command to push all arm libs as specified in 6 b

    push your binary

    set LD_LIBRARY_PATH

    run using adb shell
