bors 44808fcee6 auto merge of #7820 : pnkfelix/rust/fill-in-some-missing-rustc-lib-dependences, r=graydon r? anyone Fix #8057 This commit fixes some oversights in the Makefile where rustc could be invoked without some of its dependencies yet in place. (I encountered the problem in practice; its not just theoretical.) As written in Makefile.in, $(STAGE$(1)_T_$(2)_H_$(3)) is the way one writes an invocation of rustc where $(1) is the stage number $(2) is the target triple $(3) is the host triple. (Other uses of the macro may plug in actual values or different parameters in for those three formal parameters.) When you have invocations of $(STAGE...), you need to make sure that its dependences are satisfied; otherwise, if someone is using `make -jN` for certain (large-ish) `N`, one can encounter situations where GNU make attempts to invoke `rustc` before it has actually copied some of its libraries into place, such as libmorestack.a, which causes a link failure when the rustc invocation attempts to link in those libraries. In this case, the main prerequisite to add is TSREQ$(1)_T_$(2)_H_$(3), which is described in Makefile.in as "Prerequisites for using the stageN compiler to build target artifacts" ---- In addition to adding the extra dependences on TSREQ..., I also replaced occurrences of the pattern: TSREQ$(1)_T_$(2)_H_$(3) $$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_STDLIB_$(2)) $$(TLIB$(1)_T_$(2)_H_$(3))/$(CFG_EXTRALIB_$(2)) with: SREQ$(1)_T_$(2)_H_$(3) which is equivalent to the above, as defined in Makefile.in ---- Finally, for the cases where TSREQ was missing in tests.mk, I went ahead and put in a dependence on SREQ rather than just TSREQ, since it was not clear to me how one could expect to compile those cases without stdlib and extralib. (It could well be that I should have gone ahead and done the same in other cases where I saw TSREQ was missing, and put SREQ in those cases as well. But this seemed like a good measure for now, without needing to tax my understanding of the overall makefile infrastructure much further.)		2013-07-26 11:34:46 -07:00

The Rust Programming Language

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

Quick Start

Windows

Download and use the installer.
Read the tutorial.
Enjoy!

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-0.7.tar.gz
 $ tar -xzf rust-0.7.tar.gz
 $ cd rust-0.7
```
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 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 rustpkg, 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.
