There are large number of options accepted by this script to alter the
configuration used later in the build process. Some options to note:
- `--enable-debug` - Build a debug version of the compiler (disables optimizations)
- `--enable-debug` - Build a debug version of the compiler (disables optimizations,
which speeds up compilation of stage1 rustc)
- `--enable-optimize` - Enable optimizations (can be used with `--enable-debug`
to make a debug build with optimizations)
- `--disable-valgrind-rpass` - Don't run tests with valgrind
@ -122,10 +123,18 @@ To see a full list of options, run `./configure --help`.
Some common make targets are:
- `make tips` - show useful targets, variables and other tips for working with
the build system.
- `make rustc-stage1` - build up to (and including) the first stage. For most
cases we don't need to build the stage2 compiler, so we can save time by not
building it. The stage1 compiler is a fully functioning compiler and
(probably) will be enough to determine if your change works as expected.
- `make $host/stage1/bin/rustc` - Where $host is a target triple like x86_64-unknown-linux-gnu.
This will build just rustc, without libstd. This is the fastest way to recompile after
you changed only rustc source code. Note however that the resulting rustc binary
won't have a stdlib to link against by default. You can build libstd once with
`make rustc-stage1`, rustc will pick it up afterwards. libstd is only guaranteed to
work if recompiled, so if there are any issues recompile it.
- `make check` - build the full compiler & run all tests (takes a while). This
is what gets run by the continuous integration system against your pull
request. You should run this before submitting to make sure your tests pass

[MSYS2](http://msys2.github.io/) can be used to easily build Rust on Windows:
[MSYS2][msys2] can be used to easily build Rust on Windows:
1. Grab the latest MSYS2 installer and go through the installer.
msys2: https://msys2.github.io/
2. From the MSYS2 terminal, install the `mingw64` toolchain and other required
tools.
1. Grab the latest [MSYS2 installer][msys2] and go through the installer.
2. Run `mingw32_shell.bat` or `mingw64_shell.bat` from wherever you installed
MSYS2 (i.e. `C:\msys64`), depending on whether you want 32-bit or 64-bit
Rust. (As of the latest version of MSYS2 you have to run `msys2_shell.cmd
-mingw32` or `msys2_shell.cmd -mingw64` from the command line instead)
3. From this terminal, install the required tools:
```sh
# Update package mirrors (may be needed if you have a fresh install of MSYS2)
$ pacman -Sy pacman-mirrors
# Install build tools needed for Rust. If you're building a 32-bit compiler,
# then replace "x86_64" below with "i686". If you've already got git, python,
# or CMake installed and in PATH you can remove them from this list. Note
# that it is important that the `python2` and `cmake` packages **not** used.
# The build has historically been known to fail with these packages.

Download [MinGW from
here](http://mingw-w64.org/doku.php/download/mingw-builds), and choose the
`version=4.9.x,threads=win32,exceptions=dwarf/seh` flavor when installing. Also, make sure to install to a path without spaces in it. After installing,
add its `bin` directory to your `PATH`. This is due to [#28260](https://github.com/rust-lang/rust/issues/28260), in the future,
installing from pacman should be just fine.
```
# Make git available in MSYS2 (if not already available on path)
$ pacman -S git
$ pacman -S base-devel
```
3. Run `mingw32_shell.bat` or `mingw64_shell.bat` from wherever you installed

#### MSVC with rustbuild
For those who don't want the hassle of MSYS or MinGW, you can invoke rustbuild
directly. All you need are Python 2, CMake, and Git in your PATH (make sure you
do __not__ use the ones from MSYS!). You'll also need Visual Studio 2013 or
newer with the C++ tools. Then all you need to do is invoke the appropriate
vcvars bat file and kick off rustbuild.
```bat
CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat"
python .\src\bootstrap\bootstrap.py
```
## Building Documentation

```sh
./configure
$ ./configure
$ make docs

1. The entry point script, `src/bootstrap/bootstrap.py` is run. This script is
responsible for downloading the stage0 compiler/Cargo binaries, and it then
compiles the build system itself (this folder). Finally, it then invokes the

2. In Rust, `bootstrap` will slurp up all configuration, perform a number of
sanity checks (compilers exist for example), and then start building the

# --- Workaround ---
# The REF_OS variable was introduced to workaround linking problems when
# compiler-rt is build for the iOS simulator.
#
# Without this workaround, trying to link compiler-rt into an executable for
# the iOS simulator would produce an error like
#
# ld: warning: URGENT: building for iOS simulator, but linking in object
# file built for OSX. Note: This will be an error in the future.
#
# The underlying reason is that the iOS simulator specific configuration is
# stored in variables named like DARWIN_iossim_SYSROOT and not
# DARWIN_macho_embedded_SYSROOT. Thus, with the current setup, compiler-rt
# would be compiled against the OS X SDK and not the iPhone Simulator SDK.
#
# As a workaround we manually override macho_embedded with iossim when
# accessing the DARWIN_*_SYSROOT and DARWIN_*_BUILTIN_MIN_VER_FLAG variables.
#
# This workaround probably break builds of compiler-rt for the watchOS and
# tvOS simulators (if they weren't broken already).
