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 -the Apache License (Version 2.0), with portions covered by various BSD-like -licenses. - -See LICENSE-APACHE, and LICENSE-MIT for details. diff --git a/third_party/rust/gcc/appveyor.yml b/third_party/rust/gcc/appveyor.yml deleted file mode 100644 index 39e6845c8..000000000 --- a/third_party/rust/gcc/appveyor.yml +++ /dev/null @@ -1,35 +0,0 @@ -environment: - matrix: - - TARGET: x86_64-pc-windows-msvc - ARCH: amd64 - VS: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat - - TARGET: x86_64-pc-windows-msvc - ARCH: amd64 - VS: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat - - TARGET: i686-pc-windows-msvc - ARCH: x86 - VS: C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat - - TARGET: i686-pc-windows-msvc - ARCH: x86 - VS: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat - - TARGET: x86_64-pc-windows-gnu - MSYS_BITS: 64 - - TARGET: i686-pc-windows-gnu - MSYS_BITS: 32 -install: - - ps: Start-FileDownload "https://static.rust-lang.org/dist/rust-nightly-${env:TARGET}.exe" - - rust-nightly-%TARGET%.exe /VERYSILENT /NORESTART /DIR="C:\Program Files (x86)\Rust" - - if defined VS call "%VS%" %ARCH% - - set PATH=%PATH%;C:\Program Files (x86)\Rust\bin - - if defined MSYS_BITS set PATH=%PATH%;C:\msys64\mingw%MSYS_BITS%\bin - - rustc -V - - cargo -V - -build: false - -test_script: - - cargo test - - cargo test --features parallel - - cargo test --manifest-path gcc-test/Cargo.toml - - cargo test --manifest-path gcc-test/Cargo.toml --features parallel - - cargo test --manifest-path gcc-test/Cargo.toml --release diff --git a/third_party/rust/gcc/src/bin/gcc-shim.rs b/third_party/rust/gcc/src/bin/gcc-shim.rs deleted file mode 100644 index 43fd811d3..000000000 --- a/third_party/rust/gcc/src/bin/gcc-shim.rs +++ /dev/null @@ -1,23 +0,0 @@ -#![cfg_attr(test, allow(dead_code))] - -use std::env; -use std::fs::File; -use std::io::prelude::*; -use std::path::PathBuf; - -fn main() { - let out_dir = PathBuf::from(env::var_os("GCCTEST_OUT_DIR").unwrap()); - for i in 0.. { - let candidate = out_dir.join(format!("out{}", i)); - if candidate.exists() { - continue - } - let mut f = File::create(candidate).unwrap(); - for arg in env::args().skip(1) { - writeln!(f, "{}", arg).unwrap(); - } - - File::create(out_dir.join("libfoo.a")).unwrap(); - break - } -} diff --git a/third_party/rust/gcc/src/lib.rs b/third_party/rust/gcc/src/lib.rs deleted file mode 100644 index ea2cc9b86..000000000 --- a/third_party/rust/gcc/src/lib.rs +++ /dev/null @@ -1,898 +0,0 @@ -//!
