Man1 - pkgconf.1

is a program which helps to configure compiler and linker flags for development libraries. This allows build systems to detect other dependencies and use them with the system toolchain.

Display the supported pkg-config version and exit.

Exit with error if we do not support the requested pkg-config version.

Print all errors on the main output stream instead of the error output stream.

Do not display any errors at all.

Walk all directories listed in the

environmental variable and display information on packages which have registered information there.

Simulates resolving a dependency graph based on the requested modules on the command line. Dumps a series of trees denoting pkgconf’s resolver state.

Skip caching packages when they are loaded into the internal resolver. This may result in an alternate dependency graph being computed.

Ignore

rules in modules.

Learn about pkgconf’s configuration strictly from environmental variables.

Validate specific

files for correctness.

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.

Compute a deeper dependency graph and use compiler/linker flags intended for static linking.

Compute a simple dependency graph that is only suitable for shared linking.

Treats the computed dependency graph as if it were pure. This is mainly intended for use with the

flag.

Ignore

rules in modules when resolving dependencies.

Adds a new module search path to pkgconf’s dependency resolver. Paths added in this way are given preference before other paths.

Attempts to determine the prefix variable to use for CFLAGS and LIBS entry relocations. This is mainly useful for platforms where framework SDKs are relocatable, such as Windows.

Disables the

feature.

Sets the

variable used by the

feature.

Relocates a path using the pkgconf_path_relocate API. This is mainly used by the testsuite to provide a guaranteed interface to the system’s path relocation backend.

Disables the path relocation feature.

Exit with error if a module’s version is less than the specified version.

Exit with error if a module’s version is not exactly the specified version.

Exit with error if a module’s version is greater than the specified version.

Exit with a non-zero result if the dependency resolver was unable to find all of the requested modules.

Exit with a non-zero result if the dependency resolver uses an

module as part of its solution.

Forbids the dependency resolver from considering ’uninstalled’ modules as part of a solution.

Variables are used in query output, and some modules’ results may change based on the presence of a variable definition.

Print all seen variables for a module to the output channel.

Print all relevant

entries for a module to the output channel.

Print the modules included in either the

Dump the dependency resolver’s solution as a graphviz

file. This can be used with graphviz to visualize module interdependencies.

Display the filenames of the

files used by the dependency resolver for a given dependency set.

Print the requested values as variable declarations in a similar format as the

command.

Filter the fragment lists for the specified types.

Print the version of the queried module.

Provides an alternative setting for the

If set, enables the same behaviour as the

which is used for dumping audit information concerning installed module versions.

If set, enables additional debug logging. The format of the debug log messages is implementation-specific.

If set, disables the path relocation feature.

If set, uses MSVC syntax for fragments.

If set, follow the sysroot prefixing rules that freedesktop.org pkg-config uses.

If set to PKG_CONFIG_SYSROOT_DIR, assume that PKG_CONFIG_FDO_SYSROOT_RULES is set.
