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.
Display the supported pkg-config version and exit.
Exit with error if we do not support the requested pkg-config
Print all errors on the main output stream instead of the error
Do not display any errors at all.
Walk all directories listed in the PKG_CONFIG_PATH 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
Ignore 'Conflicts' rules in modules.
Learn about pkgconf's configuration strictly from environmental
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
Compute a deeper dependency graph and use compiler/linker flags
intended for static linking.
Exit with error if a module's version is less than the specified
Exit with error if a module's version is not exactly the
Exit with error if a module's version is greater than the
Exit with a non-zero result if the dependency resolver was able
to find all of the requested modules.
Exit with a non-zero result if the dependency resolver uses an
'uninstalled' module as part of it's solution.
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 CFLAGS or linker flag fragments that would be filtered due
to being included by default in the compiler.
Define VARNAME as VALUE. Variables are used in query output, and
some modules' results may change based on the presence of a
Print all seen variables for a module to the output channel.
Print the value of VARNAME.
Print the modules included in either the Requires field or the
Dump the dependency resolver's solution as a graphviz 'dot'
file. This can be used with graphviz to visualize module
