Manish Goregaokar 8c639d3c6e Rollup merge of #22420 - posixphreak:fix-rustup-locale, r=brson Since `tr` converts lowercase to uppercase according to system locale using `LC_CTYPE` environment variable; on some locales, rustup.sh fails to use correct variables names, thus deletes temporarily downloaded files and gives a meaningless error as shown below. This a simple fix which explictly sets `LC_CTYPE` as `C`. Here is what happens without the fix: ``` ➜ projects curl -s https://static.rust-lang.org/rustup.sh \| sudo sh rustup: CFG_CURL := /usr/bin/curl (7.22.0) rustup: CFG_TAR := /bin/tar (1.26) rustup: CFG_FILE := /usr/bin/file (5.09) rustup: CFG_SHA256SUM := /usr/bin/sha256sum (256sum) rustup: CFG_SHASUM := /usr/bin/shasum (5.61) rustup: rustup: processing sh args rustup: rustup: CFG_PREFiX := rustup: CFG_DATE := rustup: rustup: validating sh args rustup: rustup: host triple: i686-unknown-linux-gnu rustup: Downloading https://static.rust-lang.org/dist/rust-nightly-i686-unknown-linux-gnu.tar.gz to /tmp/tmp.Wz6F1ToG5z/rust-nightly-i686-unknown-linux-gnu.tar.gz % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 132M 100 132M 0 0 59947 0 0:38:31 0:38:31 --:--:-- 71204 rustup: Downloading https://static.rust-lang.org/dist/rust-nightly-i686-unknown-linux-gnu.tar.gz.sha256 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 109 100 109 0 0 107 0 0:00:01 0:00:01 --:--:-- 169 rustup: Verifying hash rustup: Extracting /tmp/tmp.Wz6F1ToG5z/rust-nightly-i686-unknown-linux-gnu.tar.gz install: looking for install programs install: install: found mkdir install: found printf install: found cut install: found grep install: found uname install: found tr install: found sed install: found chmod install: install: processing /tmp/tmp.Wz6F1ToG5z/rust-nightly-i686-unknown-linux-gnu/install.sh args install: install: CFG_DESTDiR := install: CFG_PREFiX := /usr/local install: CFG_LiBDiR := /lib install: CFG_MANDiR := /share/man install: install: validating /tmp/tmp.Wz6F1ToG5z/rust-nightly-i686-unknown-linux-gnu/install.sh args install: install: verifying platform can run binaries install: verifying destination is writable mkdir: cannot create directory `': No such file or directory install: error: can't write to destination. consider `sudo`. rustup: error: failed to install Rust ``` Notice how `i` wasn't replaced with `I`. Rust is installed as usual after the fix. Tested on Ubuntu x86 12.04 LTS. I'm not exactly sure if setting LC_CTYPE is the best solution, but there's that.		2015-02-17 06:25:21 +05:30

The Rust Programming Language

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

Quick Start

Read "Installing Rust" from The Book.

Building from Source

Make sure you have installed the dependencies:
- g++ 4.7 or clang++ 3.x
- python 2.6 or later (but not 3.x)
- GNU make 3.81 or later
- curl
- git
Download and build Rust:

You can either download a tarball or build directly from the repo.

To build from the tarball do:
```
 $ curl -O https://static.rust-lang.org/dist/rustc-nightly-src.tar.gz
 $ tar -xzf rustc-nightly-src.tar.gz
 $ cd rustc-nightly
```
Or to build from the repo do:
```
 $ git clone https://github.com/rust-lang/rust.git
 $ cd rust
```
Now that you have Rust's source code, you can configure and build it:
```
 $ ./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 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, and rustdoc, the API-documentation tool.

Building on Windows

To easily build on windows we can use MSYS2:

Grab the latest MSYS2 installer and go through the installer.
Now from the MSYS2 terminal we want to install the mingw64 toolchain and the other tools we need.

# choose one based on platform
$ pacman -S mingw-w64-i686-toolchain
$ pacman -S mingw-w64-x86_64-toolchain

$ pacman -S base-devel

With that now start mingw32_shell.bat or mingw64_shell.bat from where you installed MSYS2 (i.e. C:\msys). Which one you choose depends on if you want 32 or 64 bit Rust.
From there just navigate to where you have 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:

Windows (7, 8, Server 2008 R2), x86 and x86-64 (64-bit support added in Rust 0.12.0)
Linux (2.6.18 or later, various distributions), x86 and x86-64
OSX 10.7 (Lion) or greater, x86 and x86-64

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 a lot more documentation in the wiki.

Getting help and getting involved

The Rust community congregates in a few places:

StackOverflow - Direct questions about using the language here.
users.rust-lang.org - General discussion, broader questions.
internals.rust-lang.org - For development of the Rust language itself.
/r/rust - News and general discussion.
