pkgconf — a system for configuring build dependency information
pkgconf [options] [list of modules]
pkgconf is a program which helps to configure compiler and linker flags for development frameworks. This allows build systems to detect other dependencies and use them with the system toolchain.
--version Display the supported pkg-config version and exit. --atleast-pkgconfig-version=VERSION Exit with error if we do not support the requested pkg-config version. --errors-to-stdout Print all errors on the main output stream instead of the error output stream. --silence-errors Do not display any errors at all. --list-all Walk all directories listed in the PKG_CONFIG_PATH environmental variable and display information on packages which have registered information there. --simulate Simulates resolving a dependency graph based on the requested modules on the command line. Dumps a series of trees denoting pkgconf's resolver state. --no-cache Skip caching packages when they are loaded into the internal resolver. This may result in an alternate dependency graph being computed. --ignore-conflicts Ignore ‘Conflicts’ rules in modules. --env-only Learn about pkgconf's configuration strictly from environmental variables. --maximum-traverse-depth=DEPTH Impose a limit on the allowed depth in the dependency graph. For example, a depth of 2 will restrict the resolver from acting on child dependencies of modules added to the resolver's solution. --static Compute a deeper dependency graph and use compiler/linker flags intended for static linking.
--atleast-version=VERSION Exit with error if a module's version is less than the specified version. --exact-version=VERSION Exit with error if a module's version is not exactly the specified version. --max-version=VERSION Exit with error if a module's version is greater than the specified version. --exists Exit with a non-zero result if the dependency resolver was able to find all of the requested modules. --uninstalled Exit with a non-zero result if the dependency resolver uses an ‘uninstalled’ module as part of it's solution. --no-uninstalled Forbids the dependency resolver from considering 'uninstalled' modules as part of a solution.
--cflags, --cflags-only-I, --cflags-only-other Display either all CFLAGS, only -I CFLAGS or only CFLAGS that are not -I. --libs, --libs-only-L, --libs-only-l, --libs-only-other Display either all linker flags, only -L linker flags, only -l linker flags or only linker flags that are not -L or -l. --keep-system-cflags, --keep-system-libs Keep CFLAGS or linker flag fragments that would be filtered due to being included by default in the compiler. --define-variable=VARNAME=VALUE Define VARNAME as VALUE. Variables are used in query output, and some modules' results may change based on the presence of a variable definition. --print-variables Print all seen variables for a module to the output channel. --variable=VARNAME Print the value of VARNAME. --print-requires, --print-requires-private Print the modules included in either the Requires field or the Requires.private field. --digraph Dump the dependency resolver's solution as a graphviz ‘dot’ file. This can be used with graphviz to visualize module interdependencies.
PKG_CONFIG_PATH List of directories where ‘.pc’ files are looked up. PKG_CONFIG_SYSROOT_DIR ‘sysroot’ directory, will be prepended to every path defined in PKG_CONFIG_PATH. Useful for cross compilation.
Displaying the CFLAGS of a package: $ pkgconf --cflags foo -fPIC -I/usr/include/foo
