-# gcc-rs
-
-A library to compile C/C++ code into a Rust library/application.
-
-[![Build Status](https://travis-ci.org/alexcrichton/gcc-rs.svg?branch=master)](https://travis-ci.org/alexcrichton/gcc-rs)
-[![Build status](https://ci.appveyor.com/api/projects/status/onu270iw98h81nwv?svg=true)](https://ci.appveyor.com/project/alexcrichton/gcc-rs)
-
-[Documentation](http://alexcrichton.com/gcc-rs)
-
-A simple library meant to be used as a build dependency with Cargo packages in
-order to build a set of C/C++ files into a static archive. Note that while this
-crate is called "gcc", it actually calls out to the most relevant compile for
-a platform, for example using `cl` on MSVC. That is, this crate does indeed work
-on MSVC!
-
-## Using gcc-rs
-
-First, you'll want to both add a build script for your crate (`build.rs`) and
-also add this crate to your `Cargo.toml` via:
-
-```toml
-[package]
-# ...
-build = "build.rs"
-
-[build-dependencies]
-gcc = "0.3"
-```
-
-Next up, you'll want to write a build script like so:
-
-```rust,no_run
-// build.rs
-
-extern crate gcc;
-
-fn main() {
- gcc::compile_library("libfoo.a", &["foo.c", "bar.c"]);
-}
-```
-
-And that's it! Running `cargo build` should take care of the rest and your Rust
-application will now have the C files `foo.c` and `bar.c` compiled into it. You
-can call the functions in Rust by declaring functions in your Rust code like so:
-
-```
-extern {
- fn foo_function();
- fn bar_function();
-}
-
-pub fn call() {
- unsafe {
- foo_function();
- bar_function();
- }
-}
-
-fn main() {
- // ...
-}
-```
-
-## External configuration via environment variables
-
-To control the programs and flags used for building, the builder can set a
-number of different environment variables.
-
-* `CFLAGS` - a series of space separated flags passed to "gcc". Note that
- individual flags cannot currently contain spaces, so doing
- something like: "-L=foo\ bar" is not possible.
-* `CC` - the actual C compiler used. Note that this is used as an exact
- executable name, so (for example) no extra flags can be passed inside
- this variable, and the builder must ensure that there aren't any
- trailing spaces. This compiler must understand the `-c` flag. For
- certain `TARGET`s, it also is assumed to know about other flags (most
- common is `-fPIC`).
-* `AR` - the `ar` (archiver) executable to use to build the static library.
-
-Each of these variables can also be supplied with certain prefixes and suffixes,
-in the following prioritized order:
-
-1. `<var>_<target>` - for example, `CC_x86_64-unknown-linux-gnu`
-2. `<var>_<target_with_underscores>` - for example, `CC_x86_64_unknown_linux_gnu`
-3. `<build-kind>_<var>` - for example, `HOST_CC` or `TARGET_CFLAGS`
-4. `<var>` - a plain `CC`, `AR` as above.
-
-If none of these variables exist, gcc-rs uses built-in defaults
-
-In addition to the the above optional environment variables, `gcc-rs` has some
-functions with hard requirements on some variables supplied by [cargo's
-build-script driver][cargo] that it has the `TARGET`, `OUT_DIR`, `OPT_LEVEL`,
-and `HOST` variables.
-
-[cargo]: http://doc.crates.io/build-script.html#inputs-to-the-build-script
-
-## Optional features
-
-Currently gcc-rs supports parallel compilation (think `make -jN`) but this
-feature is turned off by default. To enable gcc-rs to compile C/C++ in parallel,
-you can change your dependency to:
-
-```toml
-[build-dependencies]
-gcc = { version = "0.3", features = ["parallel"] }
-```
-
-By default gcc-rs will limit parallelism to `$NUM_JOBS`, or if not present it
-will limit it to the number of cpus on the machine.
-
-## Compile-time Requirements
-
-To work properly this crate needs access to a C compiler when the build script
-is being run. This crate does not ship a C compiler with it. The compiler
-required varies per platform, but there are three broad categories:
-
-* Unix platforms require `cc` to be the C compiler. This can be found by
- installing gcc/clang on Linux distributions and Xcode on OSX, for example.
-* Windows platforms targeting MSVC (e.g. your target triple ends in `-msvc`)
- require `cl.exe` to be available and in `PATH`. This is typically found in
- standard Visual Studio installations and the `PATH` can be set up by running
- the appropriate developer tools shell.
-* Windows platforms targeting MinGW (e.g. your target triple ends in `-gnu`)
- require `gcc` to be available in `PATH`. We recommend the
- [MinGW-w64](http://mingw-w64.org) distribution, which is using the
- [Win-builds](http://win-builds.org) installation system.
- You may also acquire it via
- [MSYS2](http://msys2.github.io), as explained [here][msys2-help]. Make sure
- to install the appropriate architecture corresponding to your installation of
- rustc. GCC from older [MinGW](http://www.mingw.org) project is compatible
- only with 32-bit rust compiler.
-
-[msys2-help]: http://github.com/rust-lang/rust#building-on-windows
-
-## C++ support
-
-`gcc-rs` supports C++ libraries compilation by using the `cpp` method on
-`Config`:
-
-```rust,no_run
-extern crate gcc;
-
-fn main() {
- gcc::Config::new()
- .cpp(true) // Switch to C++ library compilation.
- .file("foo.cpp")
- .compile("libfoo.a");
-}
-```
-
-When using C++ library compilation switch, the `CXX` and `CXXFLAGS` env
-variables are used instead of `CC` and `CFLAGS` and the C++ standard library is
-linked to the crate target.
-
-## License
-
-`gcc-rs` is primarily distributed under the terms of both the MIT license and

-//! A library for build scripts to compile custom C code
-//!
-//! This library is intended to be used as a `build-dependencies` entry in
-//! `Cargo.toml`:
-//!
-//! ```toml
-//! [build-dependencies]
-//! gcc = "0.3"
-//! ```
-//!
-//! The purpose of this crate is to provide the utility functions necessary to
-//! compile C code into a static archive which is then linked into a Rust crate.
-//! The top-level `compile_library` function serves as a convenience and more
-//! advanced configuration is available through the `Config` builder.
-//!
-//! This crate will automatically detect situations such as cross compilation or
-//! other environment variables set by Cargo and will build code appropriately.
-//!
-//! # Examples
-//!
-//! Use the default configuration:
-//!
-//! ```no_run
-//! extern crate gcc;
-//!
-//! fn main() {
-//! gcc::compile_library("libfoo.a", &["src/foo.c"]);
-//! }
-//! ```
-//!
-//! Use more advanced configuration:
-//!
-//! ```no_run
-//! extern crate gcc;
-//!
-//! fn main() {
-//! gcc::Config::new()
-//! .file("src/foo.c")
-//! .define("FOO", Some("bar"))
-//! .include("src")
-//! .compile("libfoo.a");
-//! }
-//! ```
