.Sh NAME
|
|
.Nm pkgconf
|
|
.Nd a system for configuring build dependency information
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Ar options
|
|
.Op Ar list of modules
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
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.
|
|
.Sh GENERAL OPTIONS
|
|
.Bl -tag -width indent
|
|
.It Fl -version
|
|
Display the supported pkg-config version and exit.
|
|
.It Fl -atleast-pkgconfig-version Ns = Ns Ar VERSION
|
|
Exit with error if we do not support the requested pkg-config version.
|
|
.It Fl -errors-to-stdout
|
|
Print all errors on the main output stream instead of the error output stream.
|
|
.It Fl -silence-errors
|
|
Do not display any errors at all.
|
|
.It Fl -list-all
|
|
Walk all directories listed in the
|
|
.Va PKG_CONFIG_PATH
|
|
environmental variable and display information on packages which have registered
|
|
information there.
|
|
.It Fl -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.
|
|
.It Fl -no-cache
|
|
Skip caching packages when they are loaded into the internal resolver.
|
|
This may result in an alternate dependency graph being computed.
|
|
.It Fl -ignore-conflicts
|
|
Ignore
|
|
.Sq Conflicts
|
|
rules in modules.
|
|
.It Fl -env-only
|
|
Learn about pkgconf's configuration strictly from environmental variables.
|
|
.It Fl -maximum-traverse-depth Ns = Ns Ar 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.
|
|
.It Fl -static
|
|
Compute a deeper dependency graph and use compiler/linker flags intended for
|
|
static linking.
|
|
.It Fl -pure
|
|
Treats the computed dependency graph as if it were pure.
|
|
This is mainly intended for use with the
|
|
.Fl -static
|
|
flag.
|
|
.It Fl -no-provides
|
|
Ignore
|
|
.Sq Provides
|
|
rules in modules when resolving dependencies.
|
|
.It Fl -with-path Ns = Ns Ar PATH
|
|
Adds a new module search path to pkgconf's dependency resolver.
|
|
Paths added in this way are given preference before other paths.
|
|
.It Fl -define-prefix
|
|
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.
|
|
.It Fl -dont-define-prefix
|
|
Disables the
|
|
.Sq define-prefix
|
|
feature.
|
|
.It Fl -prefix-variable Ns = Ns Ar VARIABLE
|
|
Sets the
|
|
.Sq prefix
|
|
variable used by the
|
|
.Sq define-prefix
|
|
feature.
|
|
.It Fl -relocate Ns = Ns Ar PATH
|
|
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.
|
|
.It Fl -dont-relocate-paths
|
|
Disables the path relocation feature.

|
.El
|

|
|
Exit with error if a module's version is less than the specified version.
|
|
.It Fl -exact-version Ns = Ns Ar VERSION
|
|
Exit with error if a module's version is not exactly the specified version.
|
|
.It Fl -max-version Ns = Ns Ar VERSION
|
|
Exit with error if a module's version is greater than the specified version.
|
|
.It Fl -exists
|
|
Exit with a non-zero result if the dependency resolver was unable to find all of
|
|
the requested modules.
|
|
.It Fl -uninstalled
|
|
Exit with a non-zero result if the dependency resolver uses an
|
|
.Sq uninstalled
|
|
module as part of it's solution.
|
|
.It Fl -no-uninstalled
|
|
Forbids the dependency resolver from considering 'uninstalled' modules as part
|
|
of a solution.
