- In that case, it's necessary to prepend the search path so that pkg-config can locate the.pc files. The pkg-config program is used to retrieve information about installed libraries in the system. The primary use of pkg-config is to provide the necessary details for compiling and linking a program to a library. This metadata is stored in pkg.
- Pkg-config is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler options on the command line so an application can use gcc -o test test.c `pkg-config -libs -cflags glib-2.0` for instance, rather than hard-coding values on where to find glib (or other libraries). It is language-agnostic, so it can be used for defining the.
Pkg-config is a computer program that defines and supports a unified interface for querying installed libraries for the purpose of compiling software that depends on them. It allows programmers and installation scripts to work without explicit knowledge of detailed library path information. Pkg-config was originally designed for Linux, but it is now also available for the various BSDs. 下载mac最新版pkg-config解压,终端cd到解压文件夹下运行配置文件进行系统配置:./configure -with-internal-glib编译pkgconfig:make安装包自检测: make check安装: make install.

Command pkg-config
cmd/pkg-config is a Go-centric and GOPATH-aware pkg-config replacementfor use with the cgo tool.
** Using cmd/pkg-config with the cgo command **
To use cmd/pkg-config go install it and ensure it's in the PATH. A NOTE forLinux users: the cmd/pkg-config must be present before original/usr/bin/pkg-config in the PATH list; it is not advised to replace it,as cmd/pkg-config is not a full replacement for the pkg-config tool, e.g.it does not implement conflict and dependency resolving.
The cgo tool uses pkg-config for obtaining CFLAGS and LDFLAGS of C libraries.Example:
The '#cgo pkg-config: png' directive makes a cgo tool query a pkg-config forCFLAGS during generation of a C wrapper (--cflags flag) and for LDFLAGS duringlinking (--libs flag). The original pkg-config looks up a libpng.pc file ina directory list specified by the PKG_CONFIG_PATH environment variable plusa few other default ones. The libpng.pc file can have the following content:
A .pc file is composed of two parts - variables and keywords. Keywords mayreference pre-declared variables.
The cmd/pkg-config tool looks up for a PC file in two other places in additiondo the original pkg-config: $GOPATH and github.com.
** The cmd/pkg-config tool and $GOPATH **
The cmd/pkg-config defines standard directory layout for C libraries:

The $GOPATH tree for the example may look like the following:

The cmd/pkg-config reads the libpng.pc file from $GOPATH/lib/libpng/$GOOS_$GOARCH/libpng.pc.The .pc file written for cmd/pkg-config can use $GOPATH, $GOOS and $GOARCHbuiltin variables, which are expanded by the cmd/pkg-config during runtime.The rewritten .pc file for libpng may look like the following:
** The cmd/pkg-config tool and github.com **
Although it's advised to always use an official or self-compiled libraries fora production use, cmd/pkg-config can download a zip archive from project'sgithub.com releases for a pkg-config tag and unpack it into $GOPATH.For example in order to make the above github.com/joe/png-wrapper packagepkg-config-gettable, it's enough to zip include/ and lib/ directories:
Create release, name a tag after pkg-config and attach libpng.zip do thefile list. This would make the libpng.zip archive be accessible from the followinglink:
