A library for [Cargo build scripts](https://doc.rust-lang.org/cargo/reference/build-scripts.html) -//! to compile a set of C/C++/assembly/CUDA files into a static archive for Cargo -//! to link into the crate being built. This crate does not compile code itself; -//! it calls out to the default compiler for the platform. This crate will -//! automatically detect situations such as cross compilation and -//! [various environment variables](#external-configuration-via-environment-variables) and will build code appropriately. -//! -//! # Example -//! -//! 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 -//! [build-dependencies] -//! cc = "1.0" -//! ``` -//! -//! Next up, you'll want to write a build script like so: -//! -//! ```rust,no_run -//! // build.rs -//! cc::Build::new() -//! .file("foo.c") -//! .file("bar.c") -//! .compile("foo"); -//! ``` -//! -//! 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 a file -//! named `libfoo.a`. If the C files contain -//! -//! ```c -//! void foo_function(void) { ... } -//! ``` -//! -//! and -//! -//! ```c -//! int32_t bar_function(int32_t x) { ... } -//! ``` -//! -//! you can call them from Rust by declaring them in -//! your Rust code like so: -//! -//! ```rust,no_run -//! extern "C" { -//! fn foo_function(); -//! fn bar_function(x: i32) -> i32; -//! } -//! -//! pub fn call() { -//! unsafe { -//! foo_function(); -//! bar_function(42); -//! } -//! } -//! -//! fn main() { -//! call(); -//! } -//! ``` -//! -//! See [the Rustonomicon](https://doc.rust-lang.org/nomicon/ffi.html) for more details. -//! -//! # 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 compilers. 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. -//! * `CRATE_CC_NO_DEFAULTS` - the default compiler flags may cause conflicts in -//! some cross compiling scenarios. Setting this variable -//! will disable the generation of default compiler -//! flags. -//! * `CC_ENABLE_DEBUG_OUTPUT` - if set, compiler command invocations and exit codes will -//! be logged to stdout. This is useful for debugging build script issues, but can be -//! overly verbose for normal use. -//! * `CC_SHELL_ESCAPED_FLAGS` - if set, `*FLAGS` will be parsed as if they were shell -//! arguments (similar to `make` and `cmake`) rather than splitting them on each space. -//! For example, with `CFLAGS='a "b c"'`, the compiler will be invoked with 2 arguments - -//! `a` and `b c` - rather than 3: `a`, `"b` and `c"`. -//! * `CXX...` - see [C++ Support](#c-support). -//! * `CC_FORCE_DISABLE` - If set, `cc` will never run any [`Command`]s, and methods that -//! would return an [`Error`]. This is intended for use by third-party build systems -//! which want to be absolutely sure that they are in control of building all -//! dependencies. Note that operations that return [`Tool`]s such as -//! [`Build::get_compiler`] may produce less accurate results as in some cases `cc` runs -//! commands in order to locate compilers. Additionally, this does nothing to prevent -//! users from running [`Tool::to_command`] and executing the [`Command`] themselves.//! -//! -//! Furthermore, projects using this crate may specify custom environment variables -//! to be inspected, for example via the `Build::try_flags_from_environment` -//! function. Consult the project’s own documentation or its use of the `cc` crate -//! for any additional variables it may use. -//! -//! 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, cc-rs uses built-in defaults. -//! -//! In addition to the above optional environment variables, `cc-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]: https://doc.rust-lang.org/cargo/reference/build-scripts.html#inputs-to-the-build-script -//! -//! # Optional features -//! -//! ## Parallel -//! -//! Currently cc-rs supports parallel compilation (think `make -jN`) but this -//! feature is turned off by default. To enable cc-rs to compile C/C++ in parallel, -//! you can change your dependency to: -//! -//! ```toml -//! [build-dependencies] -//! cc = { version = "1.0", features = ["parallel"] } -//! ``` -//! -//! By default cc-rs will limit parallelism to `$NUM_JOBS`, or if not present it -//! will limit it to the number of cpus on the machine. If you are using cargo, -//! use `-jN` option of `build`, `test` and `run` commands as `$NUM_JOBS` -//! is supplied by cargo. -//! -//! # 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 cc/clang on Linux distributions and Xcode on macOS, for example. -//! * Windows platforms targeting MSVC (e.g. your target name ends in `-msvc`) -//! require Visual Studio to be installed. `cc-rs` attempts to locate it, and -//! if it fails, `cl.exe` is expected to be available in `PATH`. This can be -//! set up by running the appropriate developer tools shell. -//! * Windows platforms targeting MinGW (e.g. your target name ends in `-gnu`) -//! require `cc` to be available in `PATH`. We recommend the -//! [MinGW-w64](https://www.mingw-w64.org/) distribution. -//! You may also acquire it via -//! [MSYS2](https://www.msys2.org/), 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]: https://github.com/rust-lang/rust/blob/master/INSTALL.md#building-on-windows -//! -//! # C++ support -//! -//! `cc-rs` supports C++ libraries compilation by using the `cpp` method on -//! `Build`: -//! -//! ```rust,no_run -//! cc::Build::new() -//! .cpp(true) // Switch to C++ library compilation. -//! .file("foo.cpp") -//! .compile("foo"); -//! ``` -//! -//! For C++ libraries, the `CXX` and `CXXFLAGS` environment variables are used instead of `CC` and `CFLAGS`. -//! -//! The C++ standard library may be linked to the crate target. By default it's `libc++` for macOS, FreeBSD, and OpenBSD, `libc++_shared` for Android, nothing for MSVC, and `libstdc++` for anything else. It can be changed in one of two ways: -//! -//! 1. by using the `cpp_link_stdlib` method on `Build`: -//! ```rust,no_run -//! cc::Build::new() -//! .cpp(true) -//! .file("foo.cpp") -//! .cpp_link_stdlib("stdc++") // use libstdc++ -//! .compile("foo"); -//! ``` -//! 2. by setting the `CXXSTDLIB` environment variable. -//! -//! In particular, for Android you may want to [use `c++_static` if you have at most one shared library](https://developer.android.com/ndk/guides/cpp-support). -//! -//! Remember that C++ does name mangling so `extern "C"` might be required to enable Rust linker to find your functions. -//! -//! # CUDA C++ support -//! -//! `cc-rs` also supports compiling CUDA C++ libraries by using the `cuda` method -//! on `Build`: -//! -//! ```rust,no_run -//! cc::Build::new() -//! // Switch to CUDA C++ library compilation using NVCC. -//! .cuda(true) -//! .cudart("static") -//! // Generate code for Maxwell (GTX 970, 980, 980 Ti, Titan X). -//! .flag("-gencode").flag("arch=compute_52,code=sm_52") -//! // Generate code for Maxwell (Jetson TX1). -//! .flag("-gencode").flag("arch=compute_53,code=sm_53") -//! // Generate code for Pascal (GTX 1070, 1080, 1080 Ti, Titan Xp). -//! .flag("-gencode").flag("arch=compute_61,code=sm_61") -//! // Generate code for Pascal (Tesla P100). -//! .flag("-gencode").flag("arch=compute_60,code=sm_60") -//! // Generate code for Pascal (Jetson TX2). -//! .flag("-gencode").flag("arch=compute_62,code=sm_62") -//! // Generate code in parallel -//! .flag("-t0") -//! .file("bar.cu") -//! .compile("bar"); -//! ``` - -#![doc(html_root_url = "https://docs.rs/cc/1.0")] -#![deny(warnings)] -#![deny(missing_docs)] -#![deny(clippy::disallowed_methods)] -#![warn(clippy::doc_markdown)] - -use std::borrow::Cow; -use std::collections::HashMap; -use std::env; -use std::ffi::{OsStr, OsString}; -use std::fmt::{self, Display}; -use std::fs; -use std::io::{self, Write}; -use std::path::{Component, Path, PathBuf}; -#[cfg(feature = "parallel")] -use std::process::Child; -use std::process::{Command, Stdio}; -use std::sync::{ - atomic::{AtomicU8, Ordering::Relaxed}, - Arc, RwLock, -}; - -use shlex::Shlex; - -#[cfg(feature = "parallel")] -mod parallel; -mod target; -mod windows; -use self::target::TargetInfo; -// Regardless of whether this should be in this crate's public API, -// it has been since 2015, so don't break it. -pub use windows::find_tools as windows_registry; - -mod command_helpers; -use command_helpers::*; - -mod tool; -pub use tool::Tool; -use tool::{CompilerFamilyLookupCache, ToolFamily}; - -mod tempfile; - -mod utilities; -use utilities::*; - -mod flags; -use flags::*; - -#[derive(Debug, Eq, PartialEq, Hash)] -struct CompilerFlag { - compiler: Box<Path>, - flag: Box<OsStr>, -} - -type Env = Option<Arc<OsStr>>; - -#[derive(Debug, Default)] -struct BuildCache { - env_cache: RwLock<HashMap<Box<str>, Env>>, - apple_sdk_root_cache: RwLock<HashMap<Box<str>, Arc<OsStr>>>, - apple_versions_cache: RwLock<HashMap<Box<str>, Arc<str>>>, - cached_compiler_family: RwLock<CompilerFamilyLookupCache>, - known_flag_support_status_cache: RwLock<HashMap<CompilerFlag, bool>>, - target_info_parser: target::TargetInfoParser, -} - -/// A builder for compilation of a native library. -/// -/// A `Build` is the main type of the `cc` crate and is used to control all the -/// various configuration options and such of a compile.
