You can use this crate directly to probe for specific libraries, or use [metadeps](https://github.com/joshtriplett/metadeps) to declare all your `pkg-config` dependencies in `Cargo.toml`. This library requires Rust 1.30+. # Example Find the system library named `foo`, with minimum version 1.2.3: ```rust extern crate pkg_config; fn main() { pkg_config::Config::new().atleast_version("1.2.3").probe("foo").unwrap(); } ``` Find the system library named `foo`, with no version requirement (not recommended): ```rust extern crate pkg_config; fn main() { pkg_config::probe_library("foo").unwrap(); } ``` # External configuration via target-scoped environment variables In cross-compilation context, it is useful to manage separately PKG_CONFIG_PATH and a few other variables for the `host` and the `target` platform. The supported variables are: `PKG_CONFIG_PATH`, `PKG_CONFIG_LIBDIR`, and `PKG_CONFIG_SYSROOT_DIR`. Each of these variables can also be supplied with certain prefixes and suffixes, in the following prioritized order: 1. `_` - for example, `PKG_CONFIG_PATH_x86_64-unknown-linux-gnu` 2. `_` - for example, `PKG_CONFIG_PATH_x86_64_unknown_linux_gnu` 3. `_` - for example, `HOST_PKG_CONFIG_PATH` or `TARGET_PKG_CONFIG_PATH` 4. `` - a plain `PKG_CONFIG_PATH` Also note that `PKG_CONFIG_ALLOW_CROSS` must always be set in cross-compilation context. # License This project is licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in pkg-config-rs by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions. pkg-config-0.3.17/src/lib.rs010064400017500001750000000550221355724654200137730ustar0000000000000000//! A build dependency for Cargo libraries to find system artifacts through the //! `pkg-config` utility. //! //! This library will shell out to `pkg-config` as part of build scripts and //! probe the system to determine how to link to a specified library. The //! `Config` structure serves as a method of configuring how `pkg-config` is //! invoked in a builder style. //! //! A number of environment variables are available to globally configure how //! this crate will invoke `pkg-config`: //! //! * `PKG_CONFIG_ALLOW_CROSS` - if this variable is not set, then `pkg-config` //! will automatically be disabled for all cross compiles. //! * `FOO_NO_PKG_CONFIG` - if set, this will disable running `pkg-config` when //! probing for the library named `foo`. //! //! There are also a number of environment variables which can configure how a //! library is linked to (dynamically vs statically). These variables control //! whether the `--static` flag is passed. Note that this behavior can be //! overridden by configuring explicitly on `Config`. The variables are checked //! in the following order: //! //! * `FOO_STATIC` - pass `--static` for the library `foo` //! * `FOO_DYNAMIC` - do not pass `--static` for the library `foo` //! * `PKG_CONFIG_ALL_STATIC` - pass `--static` for all libraries //! * `PKG_CONFIG_ALL_DYNAMIC` - do not pass `--static` for all libraries //! //! After running `pkg-config` all appropriate Cargo metadata will be printed on //! stdout if the search was successful. //! //! # Example //! //! Find the system library named `foo`, with minimum version 1.2.3: //! //! ```no_run //! extern crate pkg_config; //! //! fn main() { //! pkg_config::Config::new().atleast_version("1.2.3").probe("foo").unwrap(); //! } //! ``` //! //! Find the system library named `foo`, with no version requirement (not //! recommended): //! //! ```no_run //! extern crate pkg_config; //! //! fn main() { //! pkg_config::probe_library("foo").unwrap(); //! } //! ``` //! //! Configure how library `foo` is linked to. //! //! ```no_run //! extern crate pkg_config; //! //! fn main() { //! pkg_config::Config::new().atleast_version("1.2.3").statik(true).probe("foo").unwrap(); //! } //! ``` #![doc(html_root_url = "https://docs.rs/pkg-config/0.3")] use std::collections::HashMap; use std::env; use std::error; use std::ffi::{OsStr, OsString}; use std::fmt; use std::io; use std::ops::{Bound, RangeBounds}; use std::path::{Path, PathBuf}; use std::process::{Command, Output}; use std::str; #[derive(Clone, Debug)] pub struct Config { statik: Option, min_version: Bound, max_version: Bound, extra_args: Vec, cargo_metadata: bool, env_metadata: bool, print_system_libs: bool, print_system_cflags: bool, } #[derive(Clone, Debug)] pub struct Library { pub libs: Vec, pub link_paths: Vec, pub frameworks: Vec, pub framework_paths: Vec, pub include_paths: Vec, pub defines: HashMap>, pub version: String, _priv: (), } /// Represents all reasons `pkg-config` might not succeed or be run at all. #[derive(Debug)] pub enum Error { /// Aborted because of `*_NO_PKG_CONFIG` environment variable. /// /// Contains the name of the responsible environment variable.
