# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [0.3.31] - 2024-09-23
### Fixed
- Remove double `cargo:` prefix from linker line (#168).
## [0.3.30] - 2024-02-14
### Changed
- Update documentation for cross-compilation (#161).
- Update GitHub Action CI (#160).
## [0.3.29] - 2024-01-17
### Fixed
- Detection and usage of Windows static libraries (#154).
- Passing `-Wl,-u` to the linker if specified in the pkg-config file (#154).
## [0.3.28] - 2023-12-20
### Fixed
- Pass -l:libfoo.a to linker directly (#149).
### Changed
- Improve error message when library not found (#158).
## [0.3.27] - 2023-05-03
### Added
- Support falling back to `pkgconf` if `pkg-config` is not available (#145).
### Changed
- Simplify running `pkg-config` (#144).
- Document MSRV in `Cargo.toml` via `rust-version`.
- Fix a couple of minor clippy warnings (#147).
## [0.3.26] - 2022-10-26
### Added
- Support for handling full paths to libraries in addition to normal `-l`
linker flags (#134).
## [0.3.25] - 2022-03-31
### Added
- Support for parsing `-Wl` linker arguments from the `Libs` lines and
passing them to the linker as well as making them available via
`Library::ld_args` (#131).
### Changed
- Use SPDX license format and remove obsolete badge info (#129).
## [0.3.24] - 2021-12-11
### Fixed
- Re-add `target_supported()`, which was accidentally removed in 0.3.15 (#128).
## [0.3.23] - 2021-12-06
### Changed
- Improve error messages when a `pkg-config` package can't be found (#127).
## [0.3.22] - 2021-10-24
### Fixed
- `pkg-config` compiles again with Rust 1.30 or newer. 0.3.21 accidentally
made use of API only available since 1.40 (#124, #125).
### Changed
- Switched from Travis to GitHub Actions for the CI. Travis is dysfunctional
since quite some time (#126).
## [0.3.21] - 2021-10-22
### Fixed
- Tests succeed again on macOS (#122).
### Changed
- Improve error message in case of missing pkg-config and provide instructions
how it can be installed (#121).
## [0.3.20] - 2021-09-25
### Fixed
- Use target-specific pkg-config consistently everywhere (#121, #118).
## [0.3.19] - 2020-10-13
### Added
- Add `README.md` to be displayed on crates.io (#111).
- Support for `-isystem`, `-iquote` and `-idirafter` include flags (#115).
### Changed
- Improve documentation for cross-compilation (#113).
- Allow overriding system root via the `PKG_CONFIG_SYSROOT_DIR` or `SYSROOT`
environment variable (#82).
## [0.3.18] - 2020-07-11
### Fixed
- Use `env::var_os()` almost everywhere to handle non-UTF8 paths in
environment variables, and also improve error handling around environment
variable handling (#106).
### Changed
- Default the `env_metadata` build parameter to `true` instead of `false`.
Whenever a pkg-config related environment variable changes it would make
sense to rebuild crates that use pkg-config, or otherwise changes might not
be picked up. As such the previous default didn't make much sense (#105).
## [0.3.17] - 2019-11-02
### Fixed
- Fix support for multiple version number constraints (#95)
## [0.3.16] - 2019-09-09

- Derive `Clone` for `Library` and `Debug` for `Config (#91)

# pkg-config-rs
[![Build Status](https://github.com/rust-lang/pkg-config-rs/actions/workflows/ci.yml/badge.svg)](https://github.com/rust-lang/pkg-config-rs/actions)
[![Rust](https://img.shields.io/badge/rust-1.31%2B-blue.svg?maxAge=3600)](https://github.com/rust-lang/pkg-config-rs/)
[Documentation](https://docs.rs/pkg-config)
A simple library meant to be used as a build dependency with Cargo packages in
order to use the system `pkg-config` tool (if available) to determine where a
library is located.
You can use this crate directly to probe for specific libraries, or use
[system-deps](https://github.com/gdesmott/system-deps) to declare all your
`pkg-config` dependencies in `Cargo.toml`.
This library requires Rust 1.31+.
# 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. `<var>_<target>` - for example, `PKG_CONFIG_PATH_x86_64-unknown-linux-gnu`
2. `<var>_<target_with_underscores>` - for example, `PKG_CONFIG_PATH_x86_64_unknown_linux_gnu`
3. `<build-kind>_<var>` - for example, `HOST_PKG_CONFIG_PATH` or `TARGET_PKG_CONFIG_PATH`
4. `<var>` - a plain `PKG_CONFIG_PATH`
This crate will allow `pkg-config` to be used in cross-compilation
if `PKG_CONFIG_SYSROOT_DIR` or `PKG_CONFIG` is set. You can set `PKG_CONFIG_ALLOW_CROSS=1`
to bypass the compatibility check, but please note that enabling use of `pkg-config` in
cross-compilation without appropriate sysroot and search paths set is likely to break builds.
Some Rust sys crates support building vendored libraries from source, which may be a work
around for lack of cross-compilation support in `pkg-config`.
